P115W-A4-SP is a plug-in version for NEWER Buells with an AMP 4-pin connector of the headlight harness, which is accessible under the front fairing. This is an EXTERNALLY mounted unit and does not fit inside the headlight assembly.

P115W-A4-SP is a plug-in unit for Buell Firebolt, Thunderbolt, Lightning and Ulysses models. It modulates both hi-beam and lo-beam projection lamps together. A Scothlok connector to join the Yellow and Blue wires is included and MUST be installed. This is heavy-duty version with dual MOSFETs.
The unit is 1.0"(25.4mm) by 1.35" (34.4mm), and externally mounted. The matching 4-pin AMP connector set makes this a plug-n-play operation.
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 circuits DO NOT utilize the lo-beam whatsoever!
MAX power rating is 115 watts. DO NOT EXCEED!
P115W-A4-SP 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 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.
You have complete control.
