I just bought 4 red LED bulbs. I installed the rear ones first and i was very pleased. Then i installed the front ones. The first one worked. Then, when i finished installin the second one, i put on my hazard lights, and a weired noise would come up and the blinker signals on the gauge cluster would stay lit. I concluded that it was to let me know there was some error. None of the turn signals would work. I then replaced the last one i put in with the factory bulb...they all worked normally again. I think it might be the wattage difference.(LED is less) You know cuz the computer is sensitive to that kinda stuff. Any other ideas???? Thanks!!!!
