My 2007 R1200R has the optional white turn signals, which have different lenses, bulbs, and reflectors than the amber ones. (The reflectors are different because they include the bulb socket, and the bases of the amber bulbs are different than the bases of the clear bulbs.)
I would like to trade my bike’s lenses, bulbs, and reflectors for your bike’s amber parts. My bike has 30K miles, lives inside, and the lights are in VG condition. I think the same pieces are used on some Hexhead GS, K12/K13, and F800 machines.
