Redline lists 2 used Radiator Core Support units from 1 verified sellers spanning 2 makes. The high mounted stop lamp, commonly called the third brake light, sits at the top of the rear window or on the trunk lid. Federal law has required it on all passenger vehicles since 1986. These lamps are exposed to direct sunlight all day, which degrades the lens and housing over time. The red plastic fades to pink, cracks develop, and water intrusion follows. On SUVs and hatchbacks, the third brake light is often integrated into a rear spoiler, which means replacing the spoiler assembly to fix the light. On trucks, it typically mounts at the top of the cab. LED versions are more durable than bulb-type units, but when an LED array does fail, the entire unit must be replaced since individual LEDs cannot be swapped. Our sellers note whether the unit is LED or incandescent and confirm working condition. Top makes include Mercedes Benz, Bmw.
