4th Brake Light
What's a fourth brake light? At Diode Dynamics, that's what we call an additional brake light, usually mounted lower on the vehicle in an existing lamp housing. It's not too different than the rear fog lamps found in Europe, and our kits provide a unique accent, with extra visibility on the road.
Our 4th Brake Light kits are designed to install without any modification, and add more features than a simple red light - you can upgrade your backup lights, or add a running light as well!
