R129 dome light / A124 Complete Dome Light Assembly

This is the complete dome light assembly kit for the Mercedes-Benz R129 SL-Class and A124 E-Class Cabriolet. The factory dome light system fails in multiple ways simultaneously — the inner bracket cracks, the lens yellows and crazes, and the lens frames warp from heat. We engineered this complete assembly as the definitive single-order solution, replacing every component of the dome light system with upgraded materials that will not fail again.

✅ COMPLETE ASSEMBLY KIT: This listing includes the full dome light assembly — inner bracket, lens frames, and outer cover. Everything needed for a complete system restoration in one order.

The Engineering Edge

• ASA Structural Components: The inner bracket and lens frames are moulded from engineering-grade ASA — UV-stable and heat-resistant, eliminating the cracking and warping that consistently destroys the factory components in the overhead cabin environment.
• Polycarbonate Lens: The dome light lens is manufactured from optical-grade polycarbonate — permanently clear, UV-stable, and rated for sustained cabin heat. It will not yellow, craze, or become brittle. Full light transmission is maintained for the life of the vehicle.
• Drop-In System Fitment: Every component in this kit is engineered to the exact OEM dimensions of the R129 / A124 dome light assembly. The entire system installs without modification and restores factory-correct function and appearance.
