The third (high) brake light housing may melt, resulting in a loss of electrical contact for the light, which stops working. A complete housing (contacts and lens) is needed to repair the problem. On certain vehicles, if this happens, the anti-lock brake system will not function. The brakes will work in normal mode, but not provide the ABS control.
