I just dont have a radio when I switch on the lights. How did you solve that problem?
Auxillary input and MP3 player

. After listening to the same songs and news stories all day long, it's time to listen to some REAL entertainment once the sun goes down. Perhaps your radio stations don't suck as much as ours though

I tried the ferrite rings, wrapping ballasts in alfoil, but couldn't detetct any difference. If listening to the radio is a huge priority for you, HID kit's are probably not the best option. Maybe not for all, but certainly with the ebay ones I've been buying.
Northernfarmer, HID kits not starting up first time in 9xx0 combines is not a big problem. Occasionaly, I might notice that one of the six hasn't started. Flick the lights off, flick them back on, and it fires straight up. No big deal. Have never tripped any breakers or fuses. There's nothing wrong with any connections - it's just a matter of voltage drop through the existing wiring when everything tries to start at once.
I recently fitted a set to a mate's 9600. Less than $100 Au to fit 6 lights, less than an hour to fit them all, and easily more then double the light. If you've been thinking about HID kits, you really should try it. You don't have a lot to lose. If you find that you can't possibly live without a radio at night, it's easy to swap back to the original bulbs - but I doubt you'd do that for long!
