Today I installed a set of KC driving lights behind my grill. They look real good. After instalation I verified they worked and all was good. I decided to wait until later in the evening to try to set them. As I was working on one light the other one just fadded off. Now I only have one light that works. I wired them to a switch in the cab and it works fine. Could this be a relay issue? If not, I guess it is somewhere in the wiring to the one light that is not working. It was too dark by then to see if it was the bulb, but the way it fadded out and didn't just pop, I doubt it is the bulb. Can anyone help me out? I am not much of an electrical minded person. Thanks

 

Seperate grounds for the lights? If so, check to see if it is properly grounded.

 

Nope, only had one ground off the wiring harness that came with the lights. Of course there was a ground with the switch as well, but like I said the switch is working fine.

 

Doesn't anyone know anything about electrical stuff? I was just hoping to get pointed in the right direction. I just wanted a place to start instead of ripping the whole thing apart. Anyone else had a problem like this???

 

Generally, if a light gets "dim", it's a sign of a weak/poor ground. Either a loose wire, solderless connector or just a bad ground (read: partial) to begin with.

I'm assuming that your light is not as bright as the other light?

Take a separate wire and run it from the neg side of the battery to the light housing base and touch it, or disconnect the ground wire and clip it on. See if the light brightens...

I've seen some light kits come with 2 wires from the lights, (one pos/one neg) and some lights that have a single wire, as the light is internally grounded, and uses the light's own metal as a ground, when it's bolted to your truck. These can cause the most issues...

Make sure you're using the same wires as ground, (black) and that they have good connections, and are both going to a good ground location. Resist the temptation to bolt wires/fittings to existing body screws to get a ground. The best and longest lasting grounds are the ones that are run directly to the negative terminal of the battery....
