Cheers, I did them for my girlfriend but she never really got into it so they've been barely used since they were done. They were originally a pair of tidy 1200's that I picked up pretty cheap with the reverse kits and blue leds already fitted. Ive done a few led conversions in the past and it's pretty simple if you've got a steady hand with a soldering iron! I don't know where stocks the reverse kits, they are made by 'vinyl touch' and soldered into the pcb so wouldn't fancy trying to fit them myself.
The nameplates are mirror finish steel which I had cut to size then laser etched by www.lasermarked.co.uk, they worked out about £50 for the pair, I glued the crystals on individually.
In total I reckon it cost around £500 for everything so it certainly isn't a money making opportunity if you mod a pair well!
They're relsited on ebay as they didnt sell, the item number is 200273770388
