P115W-H3-HD4 is designed with a 4-pin plug for the DayMaker LED headlamps of many new Harley models. It has matching 4-pin plug and socket for simple plug-in installation. Simply take apart the stock 4-pin connection and plug the pathBlazer in between.
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!
This unit has a software version specifically for LED drive.
DO NOT use for incandescent bulbs.
P115W-H3-HD4 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.3C-11 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 LED arrays of headlamps, so that appopriate intensities are maintained for modulation.
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.
Installation does not require any special tools. Everything needed to complete the job is in the product package.
