The OSRAM ULTRA LIFE P21W is an extended-life halogen signal lamp that lasts significantly longer than a standard P21W replacement, making it the smart choice for drivers who want fewer workshop visits and greater peace of mind. Using the universal single-filament P21W / BA15s fitting, it serves as a direct replacement for brake lights, reversing lights, front fog lights, and rear position lamps on a wide range of cars, SUVs, and light commercials.

OSRAM's ULTRA LIFE technology reinforces the filament to withstand the thermal and vibrational stresses of daily driving — delivering the same 460 lm output as the standard ORIGINAL lamp but with a lifespan up to twice as long.
