wouldnt surprise me.. my silverstar 9003 bulbs (headlights) would go after 9 months to a year when i was using them.. which is part of why i went to HID. yes they are about as white as i have ever seen from a traditional style bulb. Wagner TruView bulbs are pretty good too, but i dont think quite as good as the silverstars, not sure about longevity

one thing to note is that i always have my headlights on, no matter what.. and im on the road about 1.5 to 2 hours a day. iirc deermagnet has a long daily commute too, so possibly they just dont react well to being left on constantly
