P115W-D is totally self-contained. There are no hidden boxes or switches. There are no wires to cut or splice. The New Style is is more compact and uses latest generation electronics.
Designed for a motorcycle with dual 3-pin H4, or a Japanese H7 2-pin (with p43t expander to plug into H4 socket) headlamps - like GoldWing.
This dual unit has (1) Master and (1) Slave. Master supplies the modulation pulses to the Slave, so they are fully synchronized. Each modulator is 1.05 (26mm) round, and requires no additional room after it's plugged on the back of the bulb because of the pig-tail design.
Incandescent Halogen Headlight Bulbs:
For this Option: MAX power rating is 115 watts. DO NOT EXCEED!
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-D comes with a detachable daylight sensor, which plugs into the Master of the pathBlazer. A Sync wire then plugs into the Slave.
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 (3) 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.
Installation does not require any special tools. Everything needed to complete the job is in the product package. Follow the steps described here and refer to the Installation Manual enclosed in the product package.
Headlight Bulb Programming
By default all pathBlazer headlight flasher modules are programmed for a conventional bulb. To switch between conventional and LED bulb programming follow these simple instructions:
- Cover the Daylight sensor w/ BLACK electrical tape
- Start the engine in Low Beam
- Flick it to High Beam 6 times (about once a second)
- Leave it on the High Beam.
If programmed correctly, the headlight will flash 8 times as a confirmation of a successful LED program.
**Every time you turn on the bike the headlight will flash to let you know you have a headlight modulator. 4 flashes represents the conventional bulb programming and 8 flashes represents the LED program. |
