I have Kisan headlamp modulators on a couple bikes - not the Norton, yet.
To your questions:
- It's my understanding that the modulator actually decreases current consumption, since some of the time the headlamp is at 100% of rated draw and others (four times per second is the modulation frequency, usually) it's at 20%.
- The Kisan unit is plug and play with an H-4 bulb. Since I installed a H-4 bulb on my Norton (wired directly to battery with a relay) on my Norton without changing anything, I assume polarity doesn't much matter to the bulb and therefore wouldn't matter to the modulator.
I like the modulators a lot, BTW. Not a panacea for braindead cell-phone toting soccer moms in SUVs, but they help.
