Had a heck of a time trying to find red replacement lens for lower rear wrap around lights on my gl1500 and sidecar. They are from Drag Specialties. See red arrows in pic. Don't know how old they are. Looked on all the parts sites I could find. No luck. Then finally found them on MotoSport or so I thought. My lenses measure just under 1 3/4" by 2 3/8". Theirs were listed as 2-1/8" H x 2-3/8" W. Part no. 2040-0300. This was the only place that had what looked like an exact replacement but weren't my size. Finally bit the bullet and ordered one. Guess what? They fit. The measurements they list are wrong. So I'm including a link to the site in case anyone else needs these. I'll end up ordering 28 total and replace all mine. Some are faded, some are broken. Maybe I can save someone the frustration I had.
