KC Daylighter foglights flicker on bumpy roads
I have a 01 supercrew with a Hunter grille guard and KC 100W Daylighters. They flicker while driving offroad or when I hit any bumps. Is this from my grille guard bouncing a little, or maybe from a bad ground (they are grounded to the grille guard)...Is this normal? Does anyone else experiance this?

I could be:
1.The ground on the grille guard is not the best
- Solve by wiring the lights with 2 wires to under the hood. Your +12 to the relay as it is today & the ground to the battery or one of the grounds on the inside of the engine compartment.
2. The power to & from the relay.
- Could be a loose connector there, solve by checking that the connector to the relay, that the socket is not worn out, or larger then it should be. Or if they are terminal ends, check them.
I would not suspect that it is the terminal ends in the lamps, but that is another one to look at. If both lights go on & off at the same time, I would think this is ground or power.
That would be the things I would check first
Good luck

Definitely sounds like a connection issue in your wiring's pathway. Anything from a poorly secured earth terminal/bolt to a faulty fuse and/or fuse housing is a possibilty
The fact that they both do it tells you it's most probably the above. Rather than trouble shooting in this instance, I'd rewire everything from scatch, as it really shouldn't take you long at all.
If you're using a relay - as I hope you are - consider soldering the wires directly to the pins [wrapped in some heatshrink] rather than using crimp-like terminals. This was a pet-peeve of mine back when I did custom car audio. A faulty relay, though extrememly rare, is also a probability.
The flip side is, of cource, that, as unlikely as it is, you may quite possible have two faulty lights that have a contact issue built inside the lens' housing.
A rewire will answer this immediately.
Oh, and, no, it's not "normal."
