The modulation of the headlight can be toggled on and off by the user at any time. When the bike is started the default is modulation ON. To turn the modulation on or off simply switch your bikes high low beam switch to the opposite position, and then back to the original position within one second (this can be done with the switch in either the high or low beam position).

The Signal Dynamics Diamond Star Plug & Play Headlight Modulator is designed to automatically turn on and off at specific light levels in order to comply with the DOT's regulation of no night time modulation.

The Signal Dynamics Diamond Star Headlight Module is equipped with two levels of modulation to meet your visibility requirements. (Both are fully DOT compliant). The default level is "Max" when the bike is turned on, but can easily be toggled to "Min" or back to "Max" by simply pressing the horn button twice within one second.

The Signal Dynamics Diamond Star Headlight Module can be connected to your bikes horn wire in order to add a visual alert to your horn's audible alert. Pressing the horn will cause your headlight to modulate for 3 seconds, then return to steady on; or toggle between min and max mode for 3 seconds if it is already modulating.

In order to use the Signal Dynamics Diamond Star Plug & Play Headlight Module, you MUST have the appropriate adapter harness for your motorcycle. This kit includes the Single H4 adapter harness number 01083.

The H-4 Single harness is needed if your bike has an H4 connector on the headlight.

Note: fluorescent or LED lighting will not activate the module; to test, use an incandescent light source or move outdoors.
