Default Fog light triggers High Beams

Hi having some issues with my 06 f150. Just put in a set of led conversion headlights, suppost to be plug and play but noticed that when my low beams are on then you turn the fog lights on it switches to highbeams. Nothing happens when you turn the highbeams on unless you turn the fogs off. Tried reversing the polarity of the low beams and highs. Checking connections. But nothing. And when the fogs are on from the high beam wire it's drawing -0.02 volts. Also, I haven't done the fog light mod and works perfectly fine with halogen bulbs. It just does this with leds.

What brand are the LEDs?

Where are your fog lights hooked up at ? I have fog lights on my 06 that are connected to a toggle switch

Factory wiring that is wired to the switch with the auto/park lamps/low beam switch

I've never heard of those. A lot of us run the 4x4truckleds kits and don't have these issues.

These are the ones I have. Had talked to a few people and said they have no issues. Not sure if maybe a resistor may be needed or not.

Not that it's related, but the only problem I see with those is they don't have shields for the low beams which would cause glare for incoming traffic.

These are what a lot of us use from 4x4truckleds without issue.

You have to do the bambi mod if you want the high beam function to work properly. Several of us have had the same issue as you. Once you do the bambi mod, you will be all set. I even have LED 9005 fog bulbs on my round fogs and no issues with high/low/fog function with the bambi mod done. I dont have 4x4truckleds but I have the same light pictured by 2008_XL. They are Broview brand and have worked perfectly for 4 months now.
