I was recently in a car accident and I
was rear ended by another vehicle so
all my lights work except my tail lights
what do i do to fix this ?
Repair or replace the broken bits.
bulbs are probably broken along with pinched wires. If you are to do this yourself you will have to trace the wiring harness and see what is damaged. Not that hard on some vehicles but others the wires are all hidden behind metal panels that are hard to get at.
Report this as an additional claim to your insurance company. When repairs were done to fix the damage caused by the accident, the lights weren't fixed properly.
