looks like they are manufacturing rear clears for 749/999. I emailed them about it and should hear a reply shortly...
As far as I know, they are the ONLY ones making the clear rear turn signals. There's someone making the main brake light in clear, but not the turn signals (the back ones).
50 bucks for the rear turn signals, 65 bucks for the rear tail light LED version and 30 bucks for rear tail light (bulb version). front turn signals are same as most other places - 75 bucks
