yeah, i have the same problem, but it's on the passenger side. all the filaments in the bulbs are fine. on my car, i think there's something wrong with the black wire connected to the middle bulf of the passenger side taillight, because when i play around with it, the lights blink like normal. then after a while, it occurs again. i haven't figured it out yet, but it definitely is a electrical problem.
