How to replace tail light bulb for Audi A4 (B8)
Model years: 2008 - present
Tail lights (aka rear lamps) are integrated at the rear lamp cluster of the car, which are designed to make vehicles in sight at the hours of darkness. These lights produce red colored beam in the same way as brake lamps, though the latter develops more intensive light. In general tail lights will remain on while front low beam lights are turned on. It's relevant that any protruding objects are not restricting tail lamps, otherwise full visibility of such car will be prevented. Analogous outcome occurs in a case of an inoperative tail lamp, that's why do not delay and take care about bulb replacement.
The life-time of a bulb is limited. Sooner or later, it will burn out and will have to be replaced. Bulbs, made of high quality materials, tend to last longer. It's recommended to use well known brand replacement bulbs.
If bulb burns out right after installation, your vehicle might have a problem inside electrical system - have it checked by auto electrician.
