At Kriss this is what we view as real plug and play!
The wires that connect to the bikes factory plug are spaded. Our unit is used on a number of different bike models which have limited space in the headlight and won't accommodate more than two plugs. If we used a plug instead of spades it would require enough space for three (3) plugs - the original plus two more.
Below is how the Kriss modulator is connected
|Std H4 plug|
Installation is a simple matter of pulling the original plug from the back of the bulb then connecting it to the Kriss unit and inserting our plug in its place on the bulb. Our wires are 8" in length to give you ease and flexibility.
The original plug is disconnected.
The bulb itself is not replaced.
|Well, I just put your Harley Modulator on my bike. It took just 15 minutes. I don't see how anyone with common sense can't install one of these.|

|Our design of using a plug rather than the modulator attached directly to the bulb prevents high levels of heat generated by the bulb from transferring directly to the unit and shortening life expectancy.

"ISD" Cool Energy Modulation"©
There's an important design feature that separates a Kriss headlight modulator from others on the market aside from our exclusive "Shade Delay". 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. Maybe this doesn't make much of a difference in the short run but customers who buy Kriss know it means something when their modulator is still running 10, 15 or 20 years down the road.
is built into the standard Double Eagle circuit design because it modulates only one headlight beam and the circuit is independent of the other beam.
The Kriss engineering design incorporates the latest technology and should the modulated circuit fail it will usually operate like a normal bulb and simply stop modulating. If some unusually catastrophic event happens like a major short circuit or overload that damaged the circuit board then you always have the stock direct circuit to the other beam which is not connected to the modulator circuit, that's real protection.
Kriss "Easy TouchWire Programming" © gives you the flexibility to change from our four (4) second shade delay to instant light response depending on your riding needs.
(Changing the internal program code is simple being accomplished in a few seconds by touching a wire from the unit to +12 volts. It doesn't require any external hardware or computer)
Meets d.o.t. regulations so it's legal for headlight use in the United States, Canada and Australia.
Easy plug in unit. Doesn't require that you cut the wires on your motorcycle.
Infrared sensor 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.
This is what our light sensor looks like.
We designed our modulators back in 1992 with an Infrared sensor rather than a simple light detector, like most others today, because IR is much more stable in avoiding false triggering. Sunlight is in the IR spectrum. This has been an original feature of Kriss modulators since 1992 when we were the only company actively manufacturing headlight modulators.
Protect your motorcycle headlight or fairing - No drilling holes to install a large light sensor like this one.
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 only company with modern type 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 the left of the page you'll see that the design of our detector permits mounting it at the front of the bike and attached to a brake hose, or whatever suits your fancy, with a tie wrap or velcro. Our installation instructions explain how and where to place the detector.
It's easy to turn off. 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 modulation can be completely turned off.
The Kriss Headlight Modulator will not reduce the life of your headlight bulb.
Fits all Harley models using an H4 type 12 VDC bulb with a three prong plug (except as noted below).
(Vrod uses H7 type, 883 uses Slim-Jim, Fat-Bob dual bulb uses separate model)
Heavy Duty Version (130 watts) - This option is used primarily with higher wattage bulbs than stock bulbs but still works with the lower wattage bulbs. If using stock bulbs the heavy duty modulator is certainly going to be operating with reduced load requirements on the mosfets to help extend operational life.
(Heavy Duty model is an additional $15.00)
The latest in miniaturization
offers a small, totally solid state, rugged unit that will fit easily most motorcycles. It's only 1½" x 1½" x ¾"
Headlight modulators cannot be used on High Intensity Discharge bulbs. Some companies call their Tungsten filament Quartz Halogen bulb HID to make you believe the bulb is
something special. This is a misnomer. (HID uses a high voltage ballast to ignite a gas inside the bulb rather than a filament) See link below
(Not intended for use on Can-Bus models)
