I've changed them all at least twice now, 2nd time was with the supposedly super duper Neogauge LED's from eBay in Australia. I still
got the dark areas though!
The new bulbs are SMD CREE HID and a load of other fancy acronyms... They're meant to be the latest thing in LED lighting tech though. I won't care as long as they light up my dash without dark patches! I checked all my bulbs the other day, all working fine. I'm sure my old GTR had black clocks which was perfect with LED bulbs! I have the white Nismo 320km/h in this one, can't see why that'd matter though.
