I don't pay attention to mine because I hardly ever drive with my lights on when it's bright outside. I don't have my instrument lights at brightest setting either, but I admit, it doesn't get that bright. I wouldn't call it a problem though.
I used to always have mine on. I wired the dimmer to the accessory switch so my truck would run the dash lights. It was nice for when sitting in the truck at night surfing the web with the engine running, it allowed me to turn down that blaring light from the radio. I sort of took that idea from the 2007+ GM vehicles, although they executed it a bit better, but it was all the same.
I've grown up trained to use headlights anytime I'm moving in vehicles over 1 ton or when visiblity is less than perfect. Some times though my family would drive the truck but rarely used the lights unless it was dark. So I hard wired them on to the ignition wire so the would always run! Lol
It's a scientifically proven fact that peoples eyes are naturally drawn to light so when you are the only one in a group of cars with your lights on, they are more likely to focus on you.
This is also why racing drivers often flash or sometimes even sneak up on slower cars and then cut their lights on behind them to grab the other drivers attention so he will make way. Watch the LoneStar LeMans going on this week at COTA, a track down the road from my house. The track is a little small for the multi-class racing that they do so the faster cars will pass the slower ones several dozen times in a race. I think it's pretty cool to watch but maybe that's just me.
