Yes, the Rhombus S DF Dark is fully ECE-approved for rear use, ensuring compliance with European road traffic regulations. It can be safely used as a street-legal brake light, taillight, and turn signal on any motorcycle.
The 3-in-1 design combines three lighting functions in one unit: it serves as a taillight (steady red light), brake light (brighter red when braking), and turn signal (flashing amber). This simplifies wiring and creates a cleaner, more integrated look on your motorcycle.
Absolutely. The Rhombus S DF Dark is specifically designed for café racers and classic motorcycle restorations. Its compact size (35 x 11.5 x 11.5 mm) makes it perfect for minimalist builds, and its retro-modern aesthetic complements both vintage and contemporary custom designs.
'RL' stands for 'Rear Left,' indicating that this is the left-side rear light unit. If you need both sides, you'll also require the 'RR' (Rear Right) version.
Kellermann lights are engineered for longevity. The tinted glass is resistant to UV damage and weathering, and the assembly is built to withstand the vibrations and temperature fluctuations of motorcycle use. With proper installation, you can expect years of reliable operation.
The Kellermann Rhombus S DF Dark is available in both LED and traditional bulb versions depending on your specific order. LED versions offer lower power consumption and longer lifespan, while bulb versions provide a classic look. Check your order details or contact us for the exact configuration you're receiving.
If you have basic mechanical knowledge and the right tools, installation is straightforward. The light connects to your motorcycle's electrical system via a simple connector. However, we recommend consulting your motorcycle's service manual or having a professional technician handle the installation to ensure proper wiring and alignment.
