I know you twist off the waterproof cap and then there's a metal clip that holds the D1S lamp in but I can't seem to loosen it. I started on the drivers side because it was eay to get to. Any ideas? Do I just yank the crap out of the bracket? Help a fellow Cadenza owner out. I'm sorry.... K7 owner. I no longer have Cadenza on my arse! HeeHee. Thanks!!!
