P115W-A3-DHL is a Dual Channel
configuration. This is an EXTERNALLY mounted
unit and does not fit inside the headlight
assembly.
P115W-A3-DHL designed for BMW
motorcycles with an AMP 3-pin connector,
which is accessible at the back of the
headlight housing. The Dual High/Low
(DHL) option modulates BOTH hi-beam and
lo-beam bulbs.
■ For CAN-bus
BMWs, choose "Z" version below.
Unit is 1.0" (25.4mm) by 1.35" (34.4mm), and
externally mounted. The matching AMP
connector makes this a plug-n-play
operation.
pathBlazer circuit modulates
the hi-beam and lo-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-A3-DHL 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.
