I am in the process of switching out some of the lights to LED's in my 1996 2500 suburban. I have replaced the interior ones with no issues. I have replaced the back up lights with some monster leds and no issues.

Here is where I'm running into problems. When I install the rear turn / brake and running lights - total two bulbs on each side. I get them to light up when just the turn signal is on and when I hit the brake. When I go and turn on the running lights only... the fuse blows. I put the filiament bulbs back in and change the fuse out and I'm good to go again.

I do have the hyper blinking, but that is due to the flasher unit. I have an electronic LED compatible one ready to put in if and when I get all the turn signal lights switched out.

Here is what I'm thinking at this point.
1. Since I only have the leds in some of the running light sockets it is creating some sort of imbalance that leads to the fuse going.

OK so I've only got one theory at this point......

If I can't come up with an easy fix I have some red 57 LEDS for sale (RED)


Any help would be appreciated
