OSRAM Ultra Life P21/5W bulb, long life (7528ULT)

OSRAM Ultra Life is the perfect choice for drivers who want to minimize the need to change bulbs. This P21/5W twin filament bulb lasts up to four times longer than a standard bulb. It is an excellent solution for cars where rear lights are difficult to maintain or where bulbs wear out frequently due to vibration.

The bulb has two filaments (21W for the brake light and 5W for the tail light) and offers reliable performance every day of the year. The 2800 Kelvin color temperature ensures bright and safe light output through the red lens. By choosing the Ultra Life series, you save time and money, while reducing environmental impact thanks to a longer replacement interval. OSRAM grants an exceptionally long warranty against manufacturing defects for its products in the series (requires registration on the manufacturer's website).
