SKU P115W-A2


path-product-2P115W-A2 is a plug-in version with Heavy Duty circuitry, which can handle the newer Xenon type bulbs. This unit is EXTERNALLY mounted. 

P115W-A2 is designed for BMW, Harley Sprotster, Japanese sport bikes and other European motorcycles with a 2-pin connector with narrow spacing that plugs into the H8 or H9  Hi-beam bulb - Halogen or LED. Unit is 1.0" (25.4mm) by 1.35" (34.4mm), and externally mounted. The matching 2-pin connector makes this a plug-n-play operation.

Halogen Incandescent Headlight Bulbs:

For incandescent Halogen Headlight Bulbs MAX power rating is 115 watts. DO NOT EXCEED! 

LED Headlight Bulbs:

For this Option: Special software program controls the modulation with PWM mode for a "softer" transition.

CAN-Bus equipped bikes: 

For this option: (2) 27 Ohm resistors are used to idle current during off-cycles.

SELECT appropriate OPTION depending on the type of bulb. Options are not interchangeable!



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

P115W-A2 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

3-Click Programming: 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.

Current software version v.823A allows 8 linear steps between the high and low end. Older models have two settings only.

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 its 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.
