Well, I've been using these for nearly a year now with no problems - still on the original lamps. I use the flash (as you do) almost every day, e.g. to signal to other drivers to allow them out of side roads, etc.Originally Posted by Turbo_Steve
I reckon the reason that halogen main beams are used is because it takes around 5 seconds for the HID lamps to warm up to full brightness from cold so you don't get "instant" main beam until you've been on main beam already. Once they're warmed up, they're fine. I've never considered it a problem because the dipped beam is better than most main beams anyway
