I actually notched out the hole were the metal clip on the back of the clear lens snaps in to get them to fit, and you are right Andrew it's a tight fit. I saved the little pieces I cut out, I think with some very small pop rivet's and a thin piece of metal you could go back to the OEM light. The inverted cone red LED's reflects the red light out to the sides and kind of spreads through the lines of the clear lens, I hate it that I couldn't get a good pic of what they really looked like.
