The OSRAM LEDriving SL PY21W is a modern amber LED signal lamp that replaces the traditional PY21W halogen indicator bulb with ultra-low power consumption and a crisp, vivid amber light. Drawing just 1.3 W compared to a halogen's 21 W, it delivers a fast, bright flash for improved visibility from other road users — and its solid-state design means no fragile filament to break.

Designed as an interior or off-road upgrade, this LED lamp uses the BAU15s offset-pin bayonet base, making fitment simple and tool-free. The OSRAM LEDriving SL range is trusted by enthusiasts worldwide for its consistent colour and long service life.
