Where to Buy W176 LED Headlight Retrofits: A Complete Buyer’s Guide
Where to Buy W176 LED Headlight Retrofits
If you own a facelifted Mercedes A-Class W176 (2015-2018), upgrading to LED headlights is a popular modification that improves both visibility and the car’s appearance. The W176 facelift models came with halogen or xenon headlights from the factory, so retrofitting full LED units requires sourcing from aftermarket suppliers or genuine Mercedes parts dealers.
Genuine Mercedes LED Headlights
The most expensive but most direct option is purchasing genuine Mercedes-Benz LED headlight units. MercTeil offers the original A Class LED Headlights Set (part numbers A1769065900, A1769066000, A1769066100, A1769066200) starting around €2,400 before VAT. These are full Dynamic ILS (Intelligent Light System) units with control modules, though they come with longer lead times (10-21 weeks). You can specify your vehicle’s VIN during checkout to ensure compatibility.
Retrofit Kit and Customization Specialists
For a more affordable approach, several dedicated retrofit shops modify existing headlight housings with LED components:
- RetrofitLab – Offers complete retrofit kits designed to fit inside your existing W176 headlight housings. Their bi-LED upgrade kits for halogen headlights provide superior brightness and durability with a 2-year warranty.
- BayOptiks – Provides professional modification services. You can either ship your original headlights for LED conversion or purchase new OEM units for modification. They also offer a Pre-Built core exchange program to minimize your car’s downtime, with a 1-year service warranty.
- Xenonled.eu – Specializes in full LED headlight units specifically for the W176 Facelift LCI (2015+), offering complete replacement units rather than kits.
- KUFATEC – Offers facelift LED lighting solutions with adapters and coding modules if you have halogen headlights and want to add LED taillights alongside a headlight retrofit.
General Parts Retailers
Larger automotive parts retailers carry LED and xenon headlight options:
- AUTODOC UK – Stocks LED and xenon headlights for the W176 across a range of price points (£207.50 to £1,199.00), with options filtered by headlight type and fixture design.
Installation Considerations
Professional installation is strongly recommended. LED headlight retrofits require precise alignment and electrical work to integrate with your car’s adaptive lighting and leveling systems. If the W176 facelift you’re modifying is actually a retrofit from a pre-facelift model, note that LED performance headlights have level sensors built into the headlight unit itself, which differs from factory halogen designs. Adapters are available (part numbers A 025 545 96 26 for left and A 025 545 95 26 for right), but installation by a Mercedes specialist workshop is advisable to avoid electrical faults.
For those with mechanical experience, DIY retrofit using kit options typically takes one to three hours once the headlight is removed. The process involves opening the sealed headlight housing, installing the projector and shroud components, and resealing—though this approach requires familiarity with headlight assembly work.
Checking Compatibility
Always verify compatibility using your vehicle identification number (VIN) before ordering. Different production years, market regions, and factory headlight types (halogen vs. xenon/bi-xenon) affect which retrofit kits or replacement units will work with your W176. Most reputable suppliers allow you to enter your VIN during the ordering process to confirm fitment.
