Product Information

Made expressly for the Honda 1800 - Only unit made for under seat installation. Left light interconnect is required for both high beams to modulate. This requires removal of the left storage pocket cover to access the wiring. After the 2006 model, with the comfort package and air bag, interconnect for the left high beam bulb requires removal of top cowl/radio panel and left side panel for access to the wiring connector. Without making this secondary connection high beam operation will modulate only the right light. Low beam connection doesn't require any secondary connections and modulates both low beam bulbs.

Unit size 1.5" x 3 " x .75"

"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.

Fully integrated (Dual Processors) so you can select modulation of high beam or low beam separately or both high and low together. The two units cross talk so high and low are timed in sequence together when both are operating. If wanted all modulation can be turned off.
The high and low beam circuits on the motorcycle are not combined so you still have integrity of the two circuits.

"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.

One unit operates all four bulbs. It's not necessary to buy multiple units.
The Kriss Headlight Modulatorwill not reduce the life of you headlight bulb.
Includes high and low control switches that have a nice appearance and fit well on any upper fairing panel. These switches control the functions of the modulator. You can modulate high or low separately or both together or none if desired. If you have some kind of switch that's a favorite it's simple to use them instead.


The latest in miniaturization offers a small, totally solid state, rugged unit that fits easily under the seat.
It won't fall off like other units that attach directly to the Gold Wing 1800 bulbs and ours can be installed without removing the front fairing.



Knowledge about electronics isn't required but skills at wiring are necessary.  You can have it installed at a dealer or it's more fun having a buddy who knows about these things help you.  It's will be a great learning experience for you about to how your bike is put together.

Note: Kennedy states that their system is not compatible with headlight modulators. Using their cellphone interface generates noise in the headset. The stock Honda and J&M systems don't have this problem.

Headlight modulators cannot be used on HID (High Intensity Discharge) bulbs.
