• P115W-S unit is totally self-contained. There are no hidden boxes or switches. There are no wires to cut or splice.

• P115W-S unit is designed for 3-pin H4 or a Japanese H7 style head lamps. It's 1.25" (32mm) round, and requires only 0.4" (10mm) of additional room after it's plugged on the back of the bulb.

• P115W-S comes with a detachable daylight sensor, which simply plugs into the pathBlazer. The day light sensor functions as a switch; it stops modulation when it cannot see enough daylight.

• The Daylight Sensor has a low frequency filter to avoid false triggering. Please note that florescent lamps may NOT trigger the sensor - it needs constant incandescent light.

• Select hi-beam to modulate - as long as there's sufficient daylight. If you enter a tunnel or if it gets dark, it will stop the modulation of the hi-beam and stay steady ON. Select lo-beam to end modulation. You have the full control.
 

• P115W-S circuit modulates the hi-beam current - from 100% to about 17%. This is accomplished by using a p-channel MOSFET. If the circuit fails it is designed so that the motorcycle will have a normal high beam. For additional safety, the circuit DOES NOT utilize the lo-beam whatsoever!

• Our modulator will not affect the life of your headlight bulb because it utilizes a soft-switching technology. Soft-switching is a technique which throttles the current flow through the bulb filament, so that there's no "thermal shock" - as opposed to a sudden in-rush of current, which can damage the bulb filament or shorten it's life considerably. This is far superior than maintaining a small voltage!
