My '98 had the Show Chrome lights with the black rubber surround. I wanted the look like in the picture. My set fit great on one side, didn't fit at all on the other. I made them both fit perfect, but was uncomfortable they would come loose. Here is what I did and they work perfect/look perfect:
1. Cut the little foam part off that is stuck to the one side to (suppose to) hold the trim on once it "clicks" in place. (on one side, mine was perfect, the other it would not go on at all without fear of breaking it)
2. With the foam off both sides, you can very easily snap/click them in place as intended, but they will fall off if you ride with them this way.
3. Get small Tie Wraps/Zip ties and tie wrap them (sounds half ass I know, but do it right and it works perfect) around the mounting brackets that are already there if you have these on a Non SE bike. I did double small tie wraps on each side and my trim parts look factory, add so much to the look of my bike and I KNOW they will never fall off.
Once you make the above effort, the final result is SO worth it.
Hope this helps.
