Ok I’m running triple fog lights with SPV wiring harness’. I’m running the outer most on my factory fog switch and the inner 2 bd squadron pros off aux 1 upfitter. I’m running them through a mini relay from John and it’s been fine for months. The other night the road was flooded in a bad storm and I hit a huge pool of water that slowed the truck down and I’m assuming did something to my lighting. Tonight I remote start the truck and one of the pros is partially illuminated. The upfitter is off. Even if I turn the truck off now it stays partially illuminated. Almost like it is backlit. The fog does function to full bright. Does anyone know where I should start to find why it’s doing this? Is this wiring or the light itself. Any help appreciated.

You have a short and/or your relay is bad. Why are you using a relay? You don't need a relay at all. Your upfitters provide power and are already fused/relayed. That's what they are for.

Take the relay out of the equation and you'll be fine. I've seen this with bad relays because the relay isn't actually OFF but it's not quite ON either. It's broken.

Aux 1 is running 4 squadron pros. I’m over the amperage of the switch without the relay
