P115W-DHL is a Master/Slave configuration. There are no additional boxes to wire-in, or any wires to be cut.

P115W-DHL designed for a motorcycle with dual 3-pin H4, or a Japanese H7 2-pin style headlamps. The Dual High/Low (DHL) requires that the lo-beam bulb stays ON even when the hi-beam is switched on.

Each unit is 1.50" (38mm) round, and requires only 0.6" (15mm) of additional room after it's plugged on the back of the bulb.

Some bikes have very little room aft of the bulb socket. Use the "S" series pathBlazer for such applications.

pathBlazer circuit modulates the hi-beam current - from 100% ON to about 17% OFF. This is accomplished by using a p-channel MOSFET, which is inherently safe. The MOSFET is designed to fail in the ON state. For additional safety, the circuit DOES NOT utilize the lo-beam whatsoever!

MAX power rating is 115 watts. DO NOT EXCEED!

P115W-DHL comes with a detachable daylight sensor, which simply plugs into the pathBlazer. The daylight sensor functions as a switch; it stops modulation when it cannot see enough daylight. Since the internal circuitry is controlled by a microprocessor, it allows for customizable features.

Programmable Daylight Sensor

If you turn the high beam on and then turn the ignition on three times quickly, the sequence is interpreted as an active command to change the sensitivity.

Software version v.823A allows 8 linear steps between the high and low end.

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.

pathBlazer uses a soft-switching technique. It throttles the current flow through the bulb filament, so that there's no "thermal shock" due to a sudden inrush of current, which can damage the bulb filament or shorten it's life considerably. This is far superior than maintaining a small voltage!

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 ON steady. Select lo-beam to end modulation.

You have complete control.
