RE: hi/lo light
 

Even if you wire your lights so that they're both on at the same time, they are still going to look wierd, like one is on and one is half on. The reflectors are different, so oncoming, it looks like you have one good eye, and one lazy eye... Asthetics shouldn't be priority when it comes to lighting IMO... you should have both on during the day and night... Except sometimes it's appropriate to have just the low beams on. Very rarely, but if I'm in stop and go traffic at night, I will sometimes give the driver in front a break and turn my high beam off... A cop could pull you over for having your high beams on all the time technically.

The way the problem was described, just sounds like the low beam bulb has burned out.

Having both lights on at the same time still looks wierd because one reflector is low beam, and one is high beam... You need a low beam so you get a wider dispersion... Unless you are going to do a retrofit with Bi-Xenon projectors... get an HID kit for the low beams, but honestly, they're not that bad compared to most...
