Mercedes R129 Lens – Polycarbonate

This is a polycarbonate lens replacement for the interior dome light on the Mercedes-Benz R129 SL-Class. The factory lens — which covers the overhead dome light assembly — yellows, crazes, and becomes brittle from UV exposure and cabin heat over time. The result is a discoloured lens that dims your interior lighting and looks neglected. We re-engineered this lens in optical-grade polycarbonate to restore full light transmission and a clear, factory-correct appearance permanently.

✅ DIRECT R129 FIT: Designed specifically for the Mercedes-Benz R129 SL-Class (1989–2002). Replaces the factory dome light lens with no tools and no modification to the surrounding console.

The Engineering Edge

• Polycarbonate Construction: Manufactured from optical-grade polycarbonate — inherently UV-stable and heat-resistant. Unlike the factory lens material, polycarbonate will not yellow, craze, or become brittle regardless of cabin temperature or UV exposure. This lens stays clear permanently.
• Full Light Transmission: Polycarbonate offers superior optical clarity over the factory material, meaning your dome light appears brighter after this upgrade than it did even with a new factory lens.
• Lifetime Durability: The factory lens fails within a decade under normal use. Polycarbonate is rated for sustained UV and thermal exposure — this lens will outlast the car in normal ownership.
