Got a cracked or foggy headlight lens on your Mercedes GLA? This replacement headlight lens cover is made for the left-side headlight on 2017, 2018, and 2019 Mercedes-Benz GLA W156 models. It's made from clear ABS plastic and is designed to replace the original glass or plastic outer shell, giving your headlight a like-new, clear appearance. This is just the outer cover—not the whole headlight assembly. Before you buy, it's super important to confirm this fits your specific car. If you're unsure, send us a photo of your headlight or your VIN, and we can help verify. Installation requires separating the old lens from the housing (usually with heat) and resealing—best left to a pro or a confident DIYer with experience. Restore your light output and your car's looks.
