I bought all the parts new, chrome bezel, lens, reflector and seal. Very expensive! Ended up gluing the lens to the bezel, needed the help of clamps as they’re not a perfect fit. I didn’t use to much silicone just enough to glue them together, helps keep it cleaner. Next day it was obvious the four tabs left on the new lens won’t allow the reflector sit properly. I carfully grinded them flush, then I siliconed the internal join of the lens and bezel to make a nice smooth surface for the seal to sit against later. Note didn’t fit the seal until silicone was dry. Then fitted the seal and fitted lights to car. Had a problem with the seal protruding from the bezel on tightening the nuts. Looked terrible against the white body, so after a few refits I carefully sliced the seal around the edges so it wouldn’t squeeze out after tightening. Reckon the whole process took me 10 hours on both lights, very fiddly process, not to mention the cost of replacement if I made a mistake!
