    Hello first post here, trying to see if i can get some help solving whats going on with my girlfriends car. So i noticed when the emergency lights are turned on the right taillight wasn't flashing. The bulb was lit but not flashing. The same thing happens when using a turn signal it wont flash at all but it is still lit. So i read on numerous forums that i should change the bulbs first. But now what is happening is her right taillight is working now the left isnt working plus the third taillight on the trunk had one light out then it came on. Basically i feel like im playing musical taillights at this point. i feel like its a wiring problem but i wanted to throw this out there to see if someone has had similar experiences.

    OK,
    Some more information is needed. You didn’t state which model and any non-factory accessories are installed. And are you installing LED lamps to get everything working ?
    If you are, put in all new incandescent lamps to troubleshoot and see if you can get everything to work properly. Then and only if everything comes up working properly you can start exchanging the lamps for LEDs.

    Some LEDs will induce problems and strange symptoms, so if you start with all incandescent lamps like it was designed to run, you can eliminate any possible LED induced gremlins.

    And any non-factory installed accessories could also be creating problems due to poor wiring or being not compatible & inducing feedback voltage.
