I have the Kisan, couldn't a simpler plug and play.
That being said, I have the same mixed reaction about using it. I find that in light residential neiborhood traffic, I get the pull over reaction; finger salute, headlight flash, what-not. In heavier city boulevard traffic, it seems to work great. Not too many adverse reactions, and people will actually stay in their damn turning lane until I'm gone. I think the adverse reaction comes from the fact that a Wee/Vee has a lot of light coming out from the front on hi beams. This is not a cruiser with a round poor reflector powered by one bulb, but rather a modern efficient design reflector with 2 bulbs. Heck, it's a car headlight system!
Despite all that, I'm using it on and off (no pun intended), and will keep it.
