I'm a total newbee on HID so bear with me. I've searched but it seems like no one's done a bellof HID conversion other than the topsecret g35.
Is it doable on the G without much trouble?

 

^ yes, it's doable, and it's probably the best brand on the market. very pricey, but well worth it. everything from Bellof (H.I.D/led) is the s.hit. i just got back from japan and have had the Catz, Piaa, and Bellof compared before me, and the Bellof was the ultimate. i wish i could afford them.
