On road
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!
