OSRAM Original Line P21/5W bulb (7537)

OSRAM Original Line 7537 is a high-quality 24-volt twin-filament bulb, specially designed for combined lighting in trucks, buses and trailers. This bulb performs two functions at once: the 5W filament acts as a continuous tail light and the 21W filament as a bright brake light.

This is a genuine original spare part (OEM), which guarantees a precise fit and optimal light output. The BAY15d base is equipped with uneven pins (of different heights), which ensures that the bulb is always installed correctly in the socket. The Original Line series is the choice of professionals due to its consistent quality and excellent price-performance ratio.
