1. Is it possible to buy the halogyn lightbulbs and use them to replace regular lightbulbs, or is there somthing else that i need to buy.

2. I also need to replace the backlight holder/red/backup/thingy because it has a crack in it and iit keeps blowing out my bulbs. How much do they cost stock. I also want to get the aftermarket things sometime in the future, and is wonering where i can get them from other than ebay.
