A while back I swapped out my stock bumper with fog lights with an after market bumper that had four 3" LED fog lights. I just cut the wires to the stock fog lights and wired in the after market lights. All was fine.

Fast forward.

I now added a LED light bar to the bumper, I also wired the light bar in with the 3" LED's and now the lights do not work.

I suspect that all of the lights together are drawing too much power and the "magic" of the truck will not let them on.

As a recap, the 3" lights work alone, the light bar works alone, but combined they do not.

Is there a way around this short of wiring in a new switch and light circuit? I'd really like to just push the head light button and have them all come on.

Thanks

You could try using the 12-volt power from one of the fog lights to operate a relay to provide 12-volts to all the lights. I don't know if the low current draw to power the relay would cause the stock light monitoring system to cry foul. This is where trial and error comes in.

+1 on what Bill said. If its drawing too much current you'll need to put a relay in the circuit.
You may be able to wire the fog lights as you did and tap off of the hot side to run the relay.
That way the truck would still "see" the two fog lights so it doesn't tell you that there is a light out and hopefully the relay won't pull to much current.

That's a very good idea - better than mine.

I used the dash switch to power the relay, It seems to work great so far.
I get to use the same switch and the dash fog light symbol works.

Thanks for the suggestion.

I replaced my stock fog lights with a bracket and 2 pods per bracket. Came with a wiring harness to plug straight into stock wiring.
Problem is driver side pods come on for a bit and go off. Then come back on and go off, etc. Then they just wont come on until I turn the truck off. Then repeat. Passenger side doesnt have a problem. Curious to what you might think is the problem with the driver side set?

Lucky,
Could you share a wiring diagram of how you made the relay install? I have pod fogs that are working fine using AlfaOBD LED settings. However, my neighbor is having the same problem you were having and I'd like to get your relay mod diagram to wire a relay in his system. AlfaOBD did not correct his problem which I'm sure is an overload of the stock ability.
You've done it, I don't want to reinvent it.
Thanks

Edit:
If no diagram, where did you tap into the dash switch wiring and the fog wiring?

Sorry, I don't have a diagram, I just used the positive wire at the original fog light plug when I gut the connector off. I used that positive to energize a typical 12 relay. The lights would run off a 12v+ wire that came from the battery to the relay.

Good enough - thanks
