FWIW, those 'high priced halogens' you're referring to state right on the box that the brighter bulbs have a much shorter bulb life. Next time you're at an auto parts store, pick up the Slyvania Silverstar bulbs and look at the ratings. They clearly state the bulb life is on the order of 1/4 of the standard bulbs so people buying high priced, brighter halogen bulbs expecting long bulb life need to do their homework. They are much brighter but there's a downside. Sorry, didn't mean to derail your thread OP.
I'm running HID's on my motorcycle, 1 year strong so far and they have a harder life than those installed on a truck because of the uneven voltage at start up and pulsing voltage when the bike is idle at a stop light.
