LED bulbs for exterior lighting. (Page 2/2) Rhodesia1977 NOV 29, 02:09 PM quote Originally posted by Blacktree: The stock flasher unit will get unhappy if you use LED lights in the turn signals. But you can fix that with an electronic flasher unit, made for LED bulbs. Also, the front side marker bulbs use a floating ground. If you put LEDs in there, the side marker lights will act funny. IIRC there's a work-around using a rectifier diode. Edit to add: This stuff has been covered many times, over the years. A forum search should turn up a bunch of info. Thanks for all the info! I did check the forum before but all I found was about LED bulbs in the instrument cluster. I think I will just stay with stock for now. Thanks everyone for your input.

Yes there are two of them in the fiero, one for turn signals and one for four way.
