SBBR light

from Wikipedia, the free encyclopedia

An SBBR light is a combined parking, brake, indicator and tail light in vehicles. A special feature is that the light consists of only one housing and the four functions of the rear light are controlled by a single electronics. However, each function still has its own light source. The lamp is divided into chambers for this purpose.

SBBR lights were often used in the 1970s to keep vehicle production costs as low as possible. Compared to rear lights with multiple control electronics, the SBBR light is less safe, because if the electronics fail, all functions of the rear light are omitted. In some cases, however, there are also safety circuits that intervene in the event of failure and z. B. switch to a replacement bulb to prevent total failure of the rear lights.

It is only in modern vehicles that SBBR lights are increasingly being used again (for example in the Audi R8 ), with fail-safe light - emitting diodes being used instead of an incandescent lamp . But these lights are also used in vehicles for the mass market, such as the VW Polo V.
