What to do if your brake light is out on one side?
These must normally be replaced as an assembly and are not serviceable. A brake light out on one side only is most often a bulb or socket problem. Try the emergency-flashers and if the lamp still does not light, bulbs or sockets are the very likely cause. Inspect the bulb filament and replace any found bad.
Why is the third brake light out but the lower lights still work?
If only the third light is out and the lowers still work, see if it will flash with the emergency-flashers. If the inoperative third light flashes, with the emergency flashers, a fuse is the most likely cause.
How can I tell if my brake light bulbs are good?
Substitute a known good bulb, from the other side, to verify bulbs that cannot be confirmed otherwise. Inspect sockets closely for signs of discoloration, distortion or corrosion on the contacts. With the brakes depressed, lightly touch the terminals with a voltmeter, to check for voltage.
Is the brake light the same as the emergency light?
On vehicles where the flashers are separate from the brake lights, this will not apply. The emergency flashers often use the same wiring, bulbs and sockets as the brakes. If all lights come on, when the emergency flashers are turned on, this shows the bulbs, wires and sockets are good.
Can a bad brake light cancel a turn signal?
