Probably Flasher
emergency blinker
When your tail lights are out you can simply replace them. If they continue to blow, you may have an electrical problem.
It has been my experience that when the blinker comes on but the lights don't blink there is one or more bulbs burned out. If that is not the case check the flasher.
A simple first step would be to check the fuses to these lights, then go from there.
The next thing to check is the switch that activates the brake lights. It is probably on the master cylinder.
The tail lights are on a separate wiring than the blinker/brake lights. Look for a blown fuse or a broken/loose wire.
cheack the wireing
your problem could be in the switch its self. unfortunetly they are expensive to replace, i had to actually wire a switch direct to the blinker system.
Bad earth connection at light cluster?
Cycle the emergency 4-way flasher switch on and off a few times. If it doesn't clear up you may have a faulty signal switch.
Hazard lights are used on a vehicle in an emergency. The driver is supposed to turn the lights on the warn others that their car is experiencing some sort of problem.
If emergency brake is on 1 click it turns daytime running lights off. Pull out on emergency brake handle and see if this fixes the problem.
