Going to change my side repeaters for crystal ones, where can i get a set of crystal ones, do the old ones come off easy enough ? also going to use philips silver vision bulbs, what code bulbs are in the sides, i`ve got a white 95 STi2.

Available from Scoobysport, TSL, Scoobymania, Grahame Goode etc etc.
They come off easy...just push towards the front of the car, and lift out.
AFAIK, the bulbs atre W5W.

Make sure you get a set of silver tech bulbs to replace the orange ones, looks much better and still flashes orange
