you modified your stock light to have the blinkers in it is what your saying?
Yes, it was not super hard to do - but without a divider in the lens, it was less than ideal.
I first made a cardboard template them bought a small sheet of thin aluminum at the local Ace hardware store (or Hobby Lobby) and made the final product.
One end was bend over and attached, again, it did not require a ton of skill, finding the wiring diagram for the trailer converter/harness might of been the hardest accomplishment - and it all fit in the rear frame tube, btw.
Oh, and in Missouri, you do not have to have blinkers at all, as mentioned. Hand signals are AOK.
I put my 919 rear turnsignals on my now current ride, it is not fast enough to get out of anyones way nor is it cool without those turnsignals - there is a time and a place for everything, and yes, with smaller front and intergrated rear turnsignals, I had to be triple careful when riding -
Ride like no one see's you, not matter what.
You are invisible - sometimes, you are the target, never forget that.
