So I have a question in regards to lighting. On are current HUMMERS, we have the GOBI racks on with PIAA 1500Xt's. (4 on the front and two in the rear). With all lights on with the truck running there is no indication that the battery is suffering from the draw.

So, the new H3 will be here in a couple of weeks and the GOBI rack s going on with some addiotnal lights. I want to run PIAA 1500XT's again (4 front, 2 rear, and one for each side). Also putting two sets of 520's on the grill guard. So, I would be adding three extra sets. They will never be on without the truck running. My questios is will there be too much draw on the battery/ alternator with 12 PIAA lights on at the same time? I honestly don't know what size alternator and battery capability the H3 is capable of handleing.

Any electrical gurus?
