"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.

Fits any brand of motorcycle.
Meets d.o.t. regulations so it's legal in the United States and Canada.
Light detector automatically turns the modulator off at night. We strictly follow the d.o.t. requirements.
No drilling holes in headlight or fairing to install the light detector, which has been an exclusive feature of Kriss modulators since 1992.
Easy to install. It's a simple job to connect it to the headlight bulbs.
Connect to the high beam or low 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 Sonoran Headlight Modulator will not reduce the life of you headlight bulb.
If you are using 55 watt bulbs, which are standard in just about all bikes, this unit will work fine for you. If you're unsure about the wattage of your bulb or thinking about increasing to a higher wattage, including 100 watt bulbs, order the Heavy Duty upgrade so you are prepared.
Still works on the lower wattage bulbs.
