I'm a member of the ls1gto.com. I have a 2005 LS2 GTO. I became a member cause my Buddy has a 1999 Trans Am and for X-Mas I want to hook him up with some HID's. I know the store and the bulb # but I'm not sure about the "seal" or something like that. The store is ddmtuning.com and I'm going 4300k or 5000k for temp. 55w low and 35w for the fogs. Is there anything I need to know befor I pull the trigger on this. Thanks for the info
