Thats more or less right mikey, the speedo dial themselve have a green layer it can be removed but its a hardous task, you would be just aswell to buy different dials dependant on the model of bravo you have.
White dials where produced for the MKI 1.6 and 2.0 with the analouge mileage clock and dials where also produced for the MKII 2.0 with the digital mileage.
I had a MKII 1.8 which only showed 140mph on the clocks so couldn't use either of the above, so i used a decent scanner took the clock dials out and scanned them to my PC converted them to a Jpg image and used a photoshop software to badger n create blue\white, Orange\White, White\Orange & White\Blue faced dials i printed them on normal paper with a colour laser jet printer and then laminated they looked fine during the day but didn't give that disired neon affect at night, none the less they looked good to me.
