Answer for Triathlete
I had my dealer replace the lenses. It was a warranty issue so I dont know how they cracked open the old assymblies. There is evedence of some sort of clear glue (silicon looking) around the lens/housing joints. I remember Ron posting about tring to open the headlamp assymbly but, I don't remeber seeing the outcome. The part numbers were ascertained through a parts list I bought off ebay...so far the part #'s have been accurate. Sorry I couldn't give a step by step but maybe Ron has the answer you seek...carl
