I have a question...my tail lights are flipping out, when i turn on the headlights i have no problems with the running lights, however when i step on the brake or turn on the turn signal(which blinks fast usually telling me about a bulb) only the middle light will get bright, i just need to know if it is maybe the bulbs or the maybe the flasher unit under the dash? or if it could be something else...any help would be great, thank you!
