Was easy on one side, cut the bulb holder off a rewired with bits Ebay seller sent me (they assured me they would fit lol) the other side was a bodge as the wires for it were not as long so I couldn't do it so cut down the new repeaters opening to the lens ans used sealant to hold in place. Been like that a couple of years now not problems until my car was in the bodyshop ans they removed one and broke the metal clip that holds the lens in place and then they put half a tonne of black sealant on it ans jammed it in was really helpful when I needed to change the bulb!
