Yes, and yes. I put some 6K lights on my now-departed old Tacoma truck...frankly, I was shocked at how much light I got, and how far ahead. About a month after I put them on, late fall, I had business in Portland, a day's driving from me. Crossing on Lolo Pass, because it let me avoid a lot of tourist and truck traffic. I would see those deer, on the straights, a mile away. See the red of their eyes, no lie. I think those lights were actually painful to the deer, because they tended to walk away once they looked my way. Remember, deer are grazing animals, prey. Their instinct is never to run, because that triggers a running response in predators. So they tend to walk slowly away from what they view as a risk. So I think those intense, very-illegal lights helped a bit. BUT...the last time I hit a deer, was - again - the deer hitting me. Traversing Montana, in that same truck, about one in the morning. Had to get to Wisconsin, grab some crap, moving, and back to Montana in three days. So I was gonna do an all-nighter and nap a few hours somewhere. The motel could come when I got where I was going. I drove right into a stampede. Must have been fifty deer, all running across the road. Miracle of miracles, I missed hitting any - but the driver's mirror caught one on the head, took off the mirror, and the carcass slammed into the side of the truck, right between the start of the bed and the wheel cutout. Looked like the Jolly Green Giant gave it a kick. An independent body shop popped it out for $50, but the sheet metal remained wrinkled. But, what the hell...it was a work truck, and with 200,000 miles on it. Didn't trip the air bags, so it was all good. There is no way to avoid them, short of staying home. And the only way to limit your risk, is to keep travel between nine and four, during the day.
