There’s a certain pride that comes with keeping an older truck on the road. My 2005 GMC Sierra has been a steadfast companion, a reliable workhorse for hauling, towing, and everything in between. But time, as it does, had taken its toll, most noticeably on the face of the vehicle: the headlights. Years of relentless sun, road debris, and countless highway miles had left the original polycarbonate lenses yellowed, hazy, and pitted. They looked tired, and more importantly, they performed poorly. Night driving had become a cautious affair, with a dim, scattered beam pattern that did little to inspire confidence on dark country roads. The truck looked a decade older than it was, and its most critical safety feature was failing. Restoration kits offered a temporary fix, but I knew a full replacement was the only real solution to restore both the truck’s crisp appearance and my nighttime visibility.

What to Consider Before Upgrading Your Truck’s Headlights
A headlight assembly is more than just a cosmetic item; it’s a key solution for safety, visibility, and vehicle aesthetics. For owners of older trucks like the venerable 1999-2007 GMC Sierra and Yukon series, replacing faded, oxidized, or damaged original headlights is one of the most impactful upgrades one can make. The primary benefit is a dramatic improvement in light output, providing a clearer, brighter, and more focused beam that illuminates the road ahead, making night driving significantly safer. Aesthetically, new assemblies instantly refresh the front end of the vehicle, making it look cleaner, newer, and better maintained. It’s a functional upgrade that carries a powerful visual punch, erasing years of wear and tear in a single afternoon.
The ideal customer for this type of product is someone facing the common issue of deteriorated original headlights on a compatible GMT800 platform truck. This owner is likely budget-conscious, seeking a cost-effective alternative to expensive OEM parts, and possesses a reasonable degree of mechanical aptitude for a DIY installation. They prioritize the visual restoration of their vehicle and see the safety improvement as a crucial co-benefit. Conversely, this product might not be suitable for those who demand premium, flawless quality and a guaranteed plug-and-play experience without any potential need for adjustments. Owners of show trucks or those who want the absolute best lighting performance might consider higher-end brands or custom retrofit solutions instead.
Before investing, consider these crucial points in detail:
- Fitment & Compatibility: This is the single most important factor. Automotive parts are not one-size-fits-all. You must verify that the assembly is designed for your truck’s exact year, make, and model. For the DNA MOTORING Chrome Amber Headlights Compatible with 99-07 Sierra Yukon, it’s critical to note the exceptions: it does not fit all Denali trims and, for the 2007 model year, it only fits the “Classic” body style. Always double-check your vehicle’s specifications against the manufacturer’s compatibility list.
- Light Output & Beam Pattern: An aftermarket housing’s internal reflector geometry dictates the beam pattern. A well-designed assembly will produce a sharp, clean cutoff on low beam to avoid blinding oncoming traffic and a focused, far-reaching high beam. Poorly designed reflectors can create a scattered, blotchy pattern with dark spots, which can be less effective than even a faded OEM light. Also, confirm the required bulb types (in this case, 9005 for high beams and 9006 for low beams) and remember that bulbs are typically not included.
- Materials & Durability: The lens is almost always made from polycarbonate for its impact resistance, but its UV protective coating is what prevents yellowing over time. The quality of this coating can vary. The housing itself is typically made of ABS plastic; its thickness and the quality of the seals and gaskets are paramount. Poor seals will inevitably lead to condensation and moisture inside the lens, causing bulb failure and a foggy appearance.
- Ease of Use & Maintenance: “Ease of use” in this context refers to installation and adjustment. Does the assembly come with clear instructions? Are the adjustment screws robust and functional for proper aiming? Long-term maintenance involves keeping the lenses clean and protected. Applying a quality sealant or wax with UV inhibitors can help prolong their clarity and lifespan.
Keeping these factors in mind, the DNA MOTORING Chrome Amber Headlights Compatible with 99-07 Sierra Yukon stands out in several areas, particularly its value proposition. You can explore its detailed specifications here.

Unboxing the DNA MOTORING Kit: A First Look at Form and Finish
The package arrived containing four distinct pieces: two main headlight housings and two lower bumper light/turn signal housings, one for each side of the truck. This complete set is a major plus, ensuring a uniform look across the entire front end. Pulling them from the box, my initial impression was a mix of excitement and reservation. The chrome-plated interior reflector surfaces were bright and mirror-like, and the amber side markers had that classic, factory-correct look I was after. Visually, they were a dead ringer for the OEM style, promising to be the perfect antidote to my truck’s faded fascia.
However, upon closer inspection, the budget-friendly nature of the product became apparent. The plastic housing felt noticeably lighter and less substantial than the factory units I was about to remove. The material felt more brittle, a point of concern that was unfortunately validated by numerous user reports of units arriving with broken mounting tabs. True to the product description, no bulbs were included, nor were there any installation instructions—a clear signal that this product is aimed at those with some prior experience working on their vehicles. Overall, the initial look was promising, but the feel of the materials suggested that careful handling during installation would be critical.

In the Garage and On the Road: A Deep Dive into Performance
A product’s true worth is only revealed through hands-on testing. For the DNA MOTORING Chrome Amber Headlights Compatible with 99-07 Sierra Yukon, this meant a detailed installation process in our workshop followed by real-world driving at night. We wanted to move beyond the shiny first impression and evaluate the three aspects that matter most: how well they fit, how well they’re built, and most importantly, how well they light up the road.
Installation and Fitment: The Good, The Bad, and The Spacers
The fundamental design for replacing headlights on this generation of GM trucks is brilliantly simple. Two retaining pins hold each headlight assembly in place. Pull the pins, slide the old unit out, disconnect the bulbs, and reverse the process. In a perfect world, this is a 15-minute job. Our experience, however, reflected the mixed bag reported by many users. The main headlight housings slid into place with a bit of forceful persuasion; the fit was snug, almost too tight, but the mounting holes did eventually line up with the radiator support, allowing us to re-insert the pins.
The lower bumper lights were a different story. As one user keenly observed, the clip design on these housings is a significant weak point. After plugging in the turn signal and running light bulbs, we attempted to snap the housing into the bumper opening. It simply wouldn’t lock in securely. The clip lacked the necessary tension, leaving the light loose and prone to vibrating or even falling out. We confirmed this is a common complaint. Following the ingenious advice of another owner, we wedged a small piece of rubber tubing inside the clip mechanism to create the needed pressure. This DIY fix worked perfectly, securing the light snugly in place. While the solution was simple, it’s a modification that shouldn’t be necessary. This experience solidifies that while installation is conceptually easy, buyers should be prepared for some on-the-fly problem-solving to achieve a secure fit.
Build Quality and Long-Term Durability Concerns
This is where the DNA MOTORING Chrome Amber Headlights Compatible with 99-07 Sierra Yukon reveals its most significant compromises. The cost savings are clearly achieved through the use of thinner, more lightweight plastics. While the polycarbonate lenses themselves seem adequate, the black ABS housing feels fragile. During our careful installation, we were acutely aware of the risk of breaking a mounting tab, a frequent complaint from users who received their sets broken in the box. One user described the lights as feeling like “if you shake it too hard the cheap plastics will break,” and we found this assessment to be quite accurate. The assemblies feel delicate, lacking the reassuring heft of their OEM counterparts.
The other major durability concern is sealing. While our specific set has not yet shown signs of leakage, a significant number of users have reported moisture and condensation forming inside the housings after just a few months or a few trips through a car wash. This indicates inconsistent application of sealant at the factory. One user even had to disassemble and re-bond a lens to its body right out of the box. For prospective buyers, it might be a prudent, albeit annoying, preventative measure to run an extra bead of clear silicone around the seam where the lens meets the housing before installation. This could save a major headache down the road, as moisture inside the unit will quickly ruin the chrome reflector and cause chronic bulb failure.
Light Performance and Beam Pattern: Seeing Is Believing?
After wrestling with the fitment and contemplating the build quality, the final test was performance. We transferred a set of standard halogen 9005 and 9006 bulbs into the new housings, parked the truck facing our garage door, and waited for dusk. The results were, frankly, disappointing. While the sheer amount of light put out was brighter than the old, hazy units, the quality of the light was poor. The beam pattern was splotchy and lacked the clean, horizontal cutoff essential for low beams. We observed what one user aptly described as a “non smooth reflectance pattern on the road that was annoying to view while driving,” with visible shadows and lines projected from the internal reflectors.
Aiming the headlights proved to be another exercise in frustration. The adjustment screws felt flimsy and provided very little tactile feedback. Turning them felt vague, and their effect on the beam’s position was minimal and imprecise. We found it impossible to achieve an optimal alignment. Echoing a common complaint, the high beam’s hotspot was aimed bizarrely low, in some positions even lower than the low beam. This renders the high beams almost useless for their intended purpose of long-distance illumination. One user’s comment perfectly encapsulates the issue: “Nobody flashes high beams if I have my high beams on.” It’s a clear sign that the light output, while bright, is not being projected effectively. For those seeking a true performance upgrade, these lights do not deliver. They are an aesthetic choice first and a functional one a distant second. If you’re considering this set, we recommend pairing them with high-quality bulbs to maximize their limited potential.
What Other Users Are Saying
Our findings align closely with the broad spectrum of customer feedback. The sentiment is sharply divided, hinging almost entirely on user expectations and luck of the draw in terms of quality control. On the positive side, many users are thrilled with the cosmetic transformation. One happy customer stated, “After years of exposure to UV rays and road grime, my car’s headlights had become cloudy and dim… It was so easy to pop out the old and put in the replacements. Took less then 1/2 hour. Very satisfied with purchase.” Another noted, “These headlight assembly look good on my 06 Sierra… No water inside them,” even after using drive-through car washes.
However, the negative feedback is substantial and consistent. The most prevalent issue is damage upon arrival. “This is the second set i order because the first one was damage and once again this set was damage also,” one frustrated buyer wrote. Another had to perform a plastic-weld repair on a broken mounting point with a heat gun. The second major theme is the poor build quality and its consequences. One user summed it up bluntly: “The headlight looks really good, but don’t buy it!!! It is cheaply, cheaply made. The plastic is light and extremely fragile.” This fragility leads to the bouncing and shaking lights another user experienced, caused by a part that broke during normal driving just one day after installation.
How Does It Stack Up? DNA MOTORING vs. The Competition
When evaluating the DNA MOTORING Chrome Amber Headlights Compatible with 99-07 Sierra Yukon, it’s important to understand its place in the wider world of automotive lighting. The alternatives available often serve entirely different purposes or vehicle types, highlighting the importance of choosing the right product for your specific needs.
1. BICYACO DOT 110W 5×7 7×6 Inch LED Headlights

The BICYACO headlights are not a direct competitor but represent a different path: a technological upgrade. These are universal sealed-beam LED units designed for older vehicles like Jeep Wranglers and Cherokees that use a standard 7×6 inch housing. A user might choose this over the DNA MOTORING set if their goal is a massive leap in light output and efficiency, moving from halogen to modern LED projection. However, this requires more complex wiring and is only an option for vehicles with this specific headlight format, not the custom-shaped housings of a 1999-2007 Sierra.
2. Auto Dynasty 2008-2012 Honda Accord Headlights Chrome
- Vehicle Compatibility - These headlights are compatible with Honda Accord Sedan 2008-2012, fits 4-door models Only.
- Best Replacement - Come with set of [2] brand new headlights with turn signal(Driver and Passenger), can replace the old or damaged one for upgrading the appearance of vehicle.
The Auto Dynasty assembly for the Honda Accord is a perfect parallel to the DNA MOTORING product. It is a direct-fit, OEM-style replacement for a different popular vehicle. Someone would choose this product for the exact same reasons: to replace faded or damaged factory lights on their Accord. This comparison underscores the most critical rule of buying headlight assemblies: you must purchase the model specifically engineered for your vehicle’s year, make, and model. It’s a market defined by precise fitment, not interchangeability.
3. Yikesai HID Xenon Headlight Ballast Control Unit

This Yikesai product highlights another layer of the automotive lighting world. This is not a headlight assembly at all, but a single, critical component—a ballast—for a factory High-Intensity Discharge (HID/Xenon) lighting system found on luxury vehicles like a Cadillac Escalade or BMW. A customer would buy this for repair, not an upgrade. It’s for someone whose factory HID system has failed, and they need to replace the ballast to get their expensive, high-performance lights working again. It serves a completely different, more specialized purpose than the full halogen housing replacement offered by DNA MOTORING.
The Final Verdict: An Aesthetic Upgrade with Serious Caveats
In conclusion, the DNA MOTORING Chrome Amber Headlights Compatible with 99-07 Sierra Yukon is a product of deep compromises. On one hand, it offers an undeniable and dramatic aesthetic improvement for an aging truck at a price that is hard to beat. For a vehicle owner whose primary goal is to erase the visual wear of faded, yellowed lights on a tight budget, this four-piece kit delivers a powerful cosmetic refresh.
However, this value comes at a significant cost. The build quality is questionable, the risk of receiving a damaged product is high, the fitment often requires tinkering and modification, and the actual on-road light performance is mediocre at best. The poor beam pattern and ineffective adjustment mechanisms are serious drawbacks from a safety and usability standpoint. We can only recommend this product to a specific type of owner: a DIY-savvy individual who is mechanically inclined, prepared to potentially modify the parts to fit, and who prioritizes the visual restoration of their truck far above optimal lighting performance. If you’re looking for a simple, reliable, high-performance lighting solution, we strongly advise investing in a more reputable, albeit more expensive, brand.
