ahh they are not that great. all they do is pull the bulb closer into the base via a electric magnet, or something like that.i guess it kinda redirects the light up. i think its more so you dont loose the use of the high beams when you flip them like in the single kits.
I have the 5000k kit from Xenonlink.com. Installed them last summer and havent had one problem yet. My friend has the 6000k kit also and he hasnt had any problems. To me my 5000k is a little more blue than I would like but its still much better than stock.
well ddm shipped them quickly but there were some minor issues.my kit is the hi/lo 10k 35 watt with the black ddm mini ballasts. firstly i ordered a 55 watt kit but i received a 35 watt kit. also no instructions came with the kit. i know its not rocket science to install them but it wouldve been nice to have them. youtube helped alot.
I have 6k heads and fogs. They are from an ebay seller. I had some issues due to ballast placement (I think). I found a new vendor that is much more helpful. I like them alot and they are a billion times better then silverstars for a few bucks more.
