1200R headlight,Taillight fuse location on a 2004 model

Bulbs might all need to be replaced. Check in your fuse box under the hood of your vehicle. Take out the fuses and located what one may be blown, replace it. It is inexpensive.

Usually indicates there is a wire shorting on the lighting circuit somewhere.
check all existing wiring for chaffing or water getting into the electrics
Hope Thgis Helps

Check your fuse box....for the fuse maked TAILLIGHT....replace it.....should be back on...

Check for burned fuse. If fuse is good then you're going to need headlight switch.

check to see if there is a short in the lights by removing the bulbs if so replace bulbs and see if that works

I fixed it. The LED light needs a "load equalizer" to operate properly. Instructions said nothing of needing one. I combed the internet and found the answer. I responded to FixYa by e-mail "REPLY" and informed of the fix. Thanks for your help...I'll remember your site for future needs.

the fuses are located on the left side of the drivers foot well. these trucks have problems with rot and when they start to fall apart the beds move around and short out the taillights and youll usually lose the dash lights with the tails but the headlights are separate.

The fuse-block is located on the left end of the instrument panel under a cover. (It should have a diagram on the inside as to which fuse controls which circuit). If it isn't a fuse,it may be a defective headlight switch.

Hi rxpdooer,

There should be a diagram on the back of the fuse box lid, that tells which fuse is which, in case you didn't check it yet.

hope this helps,
Eitan.
