Dorman - OE Solutions Center High Mount Stop Light P/N:923-273
Designed to light up high and center each time you brake, the Dorman center high mount stop light, part number 923-230, is a direct-fit replacement for the 2009-2015 Audi A4, 2009-2015 Audi A4 Quattro and 2010-2015 Audi S4. Dorman reverse-engineered this third brake light assembly to match the stock unit on these vehicles, so you can replace a failed or damaged light without going back to the dealership.
The center high mount stop light works with the vehicle's other brake lamps. It illuminates when the brakes are applied, adding a raised, centered stop signal for traffic behind you. Signs this assembly may need replacing include a light that stays dark while the other brake lamps work, a cracked housing or lens, or moisture collecting inside. If the lamp assembly itself is the cause, this part replaces it. Check the circuit first, because wiring, a fuse or the brake light switch can cause similar symptoms. See the Buyer's Guide tab for complete fitment details.
