So went to put LEDS in the rear tails today and realized I have no running lights. When I press the brakes the lights come on, when I put my flashers on it seems fine, but when I put my lights on at night I have no running lamps. I thought it was the LEDS at first but turned them around and got no lights at all. Then I tried to put my stock lights back in and nothing as far as running lights either.
Any ideas of how to fix this problem?

check your fuses, Im not sure how yours is wired but on mine, the parking lamps, running lights, and instrument cluster light are all connected to a single fuse.

ya i 4got to call u back and mention the fuses cuz thats a lil 15amp fuse you may need to just swap out... awoooooo fuses r always forgotten about.

Is the problem only in the rear, or the front as well?

If it's only in the back, check the drivers side light harness to make sure the wires have not pulled out from the harness. If it's both front and rear, the problem seems like it would be somewhere from the switch to the lights, which isn't exactly easy to diagnose unfortunatly.

Luckily, the only thing effected would be the tail lights, brakes and turn are on a seperate circuit altogether. Just uh, don't drive at nite...lol.

Checked and replaced them. They keep blowing every time I turn my truck on.

stupid wanus brake shops!!

ok atleast you know the prob, check to make sure your wiring harness isn't damaged, I had the same exact problem as you and it turned out that my Liscense plate lights were grounding out, so i capped them and never had a problem since, good luck

get rid of the bulbs! if there the apc ones they dont work w/ fords. they make special leds for fords.

ya i told her a lil bit ago thats its gonna be the bulbs... go pick up sum regular red bulbs... or just get some 00 tails that look a million times better :E

yeah, she don't listen to well....

WHAT? I dont listen to well? What didnt I listen about?! hummmmmmmmm

Its not the bulbs guys as she says

check your harnesses

her running lights were fine b4 she put the LED's in

yeah hes right! They were fine this morning....sorry if I wasnt clear! I do think it is the bulbs now. Going to try a few more things tomorrow when its light out.

sorry my bad, I remember when i had those LED bulbs you could hardly tell if they were on or off unless it was dark outside.
