Look left. They are hooked to my high beam (well, the relay for them is). Originally they had blue LED surrounds hooked to the low beam, but they burned out or otherwise quit working.
I did discover, while aligning them on a hot summer night, that if the car isn't moving, and the high beams (so the driving lights are on) the grill starts to melt. They're pretty bright.
They are hooked to my high beams, so when I turn on the brights, they are on too. They shoot a beam straight down the road for a long, long way. I drive a deer infested road, often early in the morning or after dark, so they help me spot the horny rodents before I hit them.
A side benefit. If someone leaves their brights on and they are dazzling me, when I give them a flash, they switch to their dims RIGHT NOW. Probably looks like a flash bulb!
Hmm, I didn't think about a billet grill. Good idea!
