Why do some third brake lights flash?
In fact, flashing brake lights are sometimes OE (original equipment) for some car companies. European manufacturers like Mercedes-Benz and Volvo have models that come with brake lights that can flash. The reason for that is that is to create a visual distinction between slowing down and an emergency full stop.
Where is the fuse for 3rd brake light?
Should be a 10amp fuse labeled VEH CHMSL (center high mounted stop light) In the interior fuse panel on the left side of the dash.
Is there a fuse for the 3rd brake light?
If all three of your brake lights stopped working, a blown brake light fuse may be the problem. In that case, you don’t need to replace the third brake light. To determine if the fuse is the issue, you need to check it.
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.
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.
When does the brake light switch show continuity?
Using the wiring diagram, we can determine which leads should have continuity and when. The brake-lamp portion of the switch will show continuity when the brake pedal is depressed. When we release the brake pedal, it returns to the up-position. In this position, the brake light switch changes to an open-circuit.
Is the brake light the same as the emergency flasher?
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. Check for a blown fuse and be careful, as many vehicles have more than one fuse box. The owner’s manual or service data will show fuse box location.
