2016-2017 GMC Terrain SL SLE SLT Halogen Headlight with Bulb Left+Right Pair

The daytime running lights glow evenly and give the vehicle a more current appearance. After aiming the projectors, the low beams provide clear coverage through dark intersections and curved roads.

The projector beam has a defined cutoff and illuminates the lane without excessive glare. Black inner housings sharpen the front-end appearance while retaining a refined factory-style finish.

Nighttime visibility improved immediately, with a broad pattern that makes roadside details easier to spot. The housings sit flush with the surrounding panels and remain steady over uneven pavement.

This was a very easy replacement for my damaged taillight on my Yukon XL. I can’t tell the difference from the factory taillight or the replacement.
Four stars because there were no included instructions to replace the tail light. Fortunately, there were adequate instructions on YouTube.

This tail light assembly was a perfect fit on my 2017 GMC Yukon XL Denali and installed without any issues. The housing lined up correctly, the mounting points matched up exactly, and it connected properly without any modifications. Once installed, it looked identical to the original factory unit and blended seamlessly with the other side.
The overall appearance and fit feel identical to OEM quality, which is exactly what I was hoping for in an aftermarket replacement. It restored the clean, original look of the rear end without paying dealership pricing. If you’re looking for a straightforward driver-side replacement that fits properly and looks factory-correct, this is an excellent option. I’m very satisfied with the purchase.
