I recenty swaped out all the bulbs on my 05 dmax to led bulbs in the front turn signals and daytime running lights. Some ebay led tail lights. I put on load resistors, it all works fine. This week i swapped out regular bulbs on my 84 s10 blazer to leds. I bought a electronic flasher and it wouldnt make bulbs flash. Ordered load resistors and installed. When i hit the turn signals left or right. They flash like warning lights are on. No matter what i do. If i put a regular bulb in tail lights and leave leds up front it works fine. So anyone have any insight on this?
