For most SINGLE headlamps
P75W unit is designed to modulate a single headlamp upto 75W max - for most Harleys, Honda, Suzuki, Yamaha, Kawasaki cruiser models.
P75W unit is very compact - only 0.6" (15mm) square. It can easily fit inside even a small headlight bucket or wired-in with the headlight harness.
■ Install it in-line with the hi-beam wire, as shown. No ground wire or ground connection required!
■ If it's hooked-up the wrong way, the circuit shuts down and the Status LED flashes rapidly.
■ If there's a short or if the load is more than 75W, the circuit shuts down. Just like a fuse. The Satus LED shuts off. You can reset the unit after the short is fixed.
The internal circuitry is controlled by a microprocessor, which allows precise flash patterns, overload detection and reverse polarity protection.
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 lo-beam remains untouched, so you won't be without headlights.
P75W comes with a detachable daylight sensor (SN-3M), which simply plugs into the pathBlazer. The daylight sensor functions as a switch; it stops modulation when it cannot sense 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 filament of the headlamp, so that appopriate intensities are maintained for modulation. This also prevents any "thermal shock" to the bulb filament, which can damage or shorten it's life.
Select hi-beam to modulate during daytime. If you enter a tunnel or if it gets dark, it will stop the modulation of the hi-beam and stay ON steady. Or select lo-beam to end modulation.
■ DO NOT use on headlight bulbs higher than 75W.
■ DO NOT use on bikes with bulb-check system or CAN-bus monitoring.
