P115W-S unit is totally
self-contained. There are no hidden boxes or switches. There are no
wires to cut or splice.
P115W-S unit is designed for 3-pin H4 or a Japanese H7 2-pin
style headlamps. It's 1.25" (32mm) round, and requires NO
ADDITIONAL SPACE after it's plugged on the back of the bulb.
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-S 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.
Current 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.
