My truck is at stock height and occasionally the glare from headlights behind me gets bothersome. If I'm not planning on passing (and don't have the cab full, hindering my ability to look over my shoulders) I just fold the mirrors in. No big deal, and definitely not worth me trying to retaliate.
The Silverstars (and Silverstar Ultras) are decent bulbs. I switched to the Ultras a few years back after driving home in South Louisiana in a heavy rain. Five-foot deep ditches were flooded and the standard bulbs just didn't illuminate enough for me to see well. I made it home, but had to drive in the middle of the road to be safe for a mile or two.
I use Xtravision bulbs now, after tiring of replacing the Silverstars every 8-12 months. I found them for around $5 each at Lowes (compared to a minimum of $15 per 2-pack at most auto stores) and picked up enough low and high beam bulbs to last for my truck's lifetime and then some. Thought they were on clearance, then saw them restocked a year later for the same price.
