This officer needs some learnin'!

I have a High and Low beam on my 2010 RTS.

There is a shutter that moves when high/low beam is activated. For low beam, part of the bulb is covered up. There are not separate filaments for high or low beam. The shutter movement is what causes the click when changing from one setting to the other. :thumbup:

It continuously changes from high beam, to low beam. It makes you more visible, while completely annoying everyone around you!

Actually, it interrupts the ground signal to the headlight causing it to "flash" on and off. The legal ones are required to flash within a certain frequency range, can be disabled (on my two-wheeler it was simply changing from low to high beam and back within one second) and it cannot flash at night. So they (are supposed to) have a day/night sensor so they do not flash at night.

Mine did what it was supposed to - attract attention. In fact, it was very common for drivers to pull into the other lane when I was following them - not my intent, but thank you for the free pass. I never had anyone flash their lights at me, and I always felt like I was better seen that way than a bright colored helmet or jacket. With the headlight modulator, I was seen much sooner than with bright colors.

Just my two cents

Nope. From the code:

(d) The modulator switch must be
wired in the power lead of the beam
filament being modulated and not in
the ground side of the circuit.

The rest of your comments are correct.
