Product Information

When using our simple installation procedure for the Fat Bob H13 bulbs there's enough space in the headlight housing for the unit and wiring to the bulbs. If this installation was made fully plug and play with original plugs there wouldn't be enough room in the headlight for the modulator plus the additional four plugs and wiring. Our installation make connections only to the high beam circuits with no changes to the other wiiring so it's a simple installation taking just several minutes.
No drilling to attach a Kriss Light detector.	We provide you with these crimp connectors that can be quickly and easily installed in the wires to accept plug & play installation of our modulator. You also can connect this unit to the low beam rather than the high beam depending on your choice and riding preferences.

 

"ISD" Modulation"© (Here's something you should read)
There's an important design feature that separates a Kriss modulator from others on the market. The program code for our microprocessor sets an "Instant Step Down" (ISD) method of controlling the current flow to the bulb. Our circuit design creates a more crisp and brighter modulation because it doesn't waste current with a heat generating delay like those that slowly throttle down the current flow. It's a characteristic of a mosfet (the switching transistor) to get hot when changing state slowly so we put in the additional engineering to make it work fast. When the filament is at peak temperature our "ISD" sets the bottom level with lighting speed allowing the filament to cool naturally according to the design and material of the filament used in the bulb. An obvious benefit is that the filament is not going to be stressed by operating outside it's metallurgical limits. Our modulators last longer because they run cold and don't create life shortening heat like the others you'll find on the market.

Kriss "Easy TouchWire Programming" © gives you the flexibility to change from our shade delay to instant response to any light changes.
"Kriss Shade Delay"© is designed into the
operating code so the modulation is not interrupted
during those brief moments when you pass quickly under
an overpass or behind a shaded area like a large tree. Our delay
to light changes is an actual time delay and not an afterthought in an
effort to copy the Kriss design by adjusting the light sensor to compensate for the
changes. Adjusting the light sensor simply disrupts the effectiveness of the normal shut off and turn on times established by the d.o.t. regulations.

Meets d.o.t. regulations so it's legal in the United States and Canada.
Light detector automatically turns the modulator off at night. It's not legal to operate, even momentarily, at night and we strictly follow the d.o.t. requirements.

No drilling holes in headlight or fairing to install the light detector.
This has been an original feature of Kriss modulators since 1992.
Here's why we feel it's not good to drill a hole in your headlight housing
to install a light detector. In an effort to be fancy others out there use a sensor
that's built into a small metal bezel that's installed in a hole with a fastening nut.
This requires drilling a hole. We were the first out with modulators in the early 90's
and realized early on that drilling a hole in a chrome headlight housing or other surface
violates the integrity of the metal and plating setting it up for inter granular corrosion caused
by humidity and seen by the subsequent separation of the plating which migrates out from the hole.
This is often referred to as blistering of the chrome plating. If you look at the picture on our web page you
will see that our detector is mounted at the front of the bike and attached to a brake hose or whatever suits your fancy with a tie wrap or velcro.

Modulates the high beam. Just like all of our modulators it's easy to turn off during the day when it's operating, simply select the other beam or it can be installed so it may be completely turned off.
The Kriss Headlight Modulator will not reduce the life of you headlight bulb.
The latest in miniaturization offers a small, totally solid state, rugged unit that fits easily most motorcycles. It's only 1.5" x 1.5" x 3/4".

Heavy Duty upgrade is available for this modulator.
(select this $15.00 option when ordering )
(for bulbs exceeding 80w up to 110 watts total)
Still works with lower wattage bulbs.
