I just installed all led running and signal bulbs. I used the sylvania zevo led bulbs. The running lights light up like they should but when i turn the signal lights on they just light up but don't blink. I didnt use any load resistors. Any ideas?? Will load resistors help?? I first tried some cheap ebay leds and they all worked fine but they just weren't very bright. The incandescent bulbs were brighter than the ebay led. So i got some sylvania zevo led and man they are alot brighter. 4 1157, 2 194 in red in rear and 2 1157 and 2 194 in amber in front. And 1156 white for reverse lights all zevo leds also i changed the flasher relay with an American autowire led flasher relay
