Ah, the joys of moisture getting into your Audi tail light. As they age, your Audi tail lights begin to corrode just like everything else. The result can be a bad ground inside our Audi tail light, and that can wreak havoc on all your lighting components. Some symptoms of a bad Audi tail light include no light at all, dimming of other lights when your Audi tail light is on, and pulsing light coming from your Audi tail light when the blinkers are on. Some of these symptoms can be caused by something as simple as a bad Audi tail light bulb. In other cases, replacement of the entire Audi tail light assembly is necessary. Either way, we can help.
