L20 D2S/D4S adapter holders

The Riglow™ L20 is listed as a retaining adapter for selected D2S/D4S headlight bulb installations. It is a mechanical mounting accessory, not a bulb, ballast, driver or complete headlight.

Confirm the exact application

The earlier listing names BMW E39, E60, E61, F10 and F11. These are unverified application references, not confirmed fitment for every year, trim or headlight assembly. Compare your original holder, mounting tabs, locking geometry, bulb base and housing clearance before ordering.

The earlier specification list also names D2R and D4R, but compatibility with these applications is not verified. Do not assume D2S, D2R, D4S and D4R bulbs or mounting arrangements are interchangeable. Confirm the exact bulb and headlight combination with the supplier.

Mechanical fit is not electrical compatibility

A retaining adapter does not establish that an LED or xenon bulb is electrically compatible with the vehicle, ballast or driver. Follow the vehicle and bulb supplier's application-specific instructions. Have a qualified installer assess suitability when compatibility is uncertain.

Direct-fit, OEM-equivalent, plug-and-play and no-modification installation are not established. The adapter alone does not guarantee correct beam alignment, reduced glare, vibration-free retention, improved visibility or maximum light output. Confirm suitable seating, retention and lighting operation after installation.

Listed construction and package

The earlier listing describes black, high-temperature ABS plastic. Color and material are listing details; resin grade and temperature limits have not been independently verified.

Listed package: two Riglow™ L20 D2S/D4S adapter holders. Bulbs, electrical conversion components and additional accessories are not established as included.

Warranty

L20 has no warranty.
