Motorcycle Headlight Modulators

A motorcycle headlight modulator is a motorcycle safety device that rapidly varies the intensity of a motorcycle headlight from between 20% and 100% of normal steady-burning power. Federal law requires that this “modulating” be between 200 and 280 beats per minute to differentiate between the headlight modulation and emergency vehicle flashers.

Statistics show that over three-fourths of multi-vehicle motorcycle crashes occur at intersections. Of these, the great majority are caused when another vehicle invades a motorcycles right-of-way. These statistics aren't new, but one still wonders how this scenario repeats so frequently. The answer can be found in four words we've all heard too often: "I didn't see them".

As motorcyclists, those four words should not be taken lightly. They provide one of our best insights into becoming safer riders. Acknowledging that we're nearly invisible to other drivers is our first step in learning to increase our visibility. Another great step is the addition of a "headlight modulator".

It has long been recognized that the human eye sees a blinking light more easily than a constant light. That is why construction barriers have flashing amber lights; emergency vehicle headlights flash and also why headlight modulators are so effective for motorcycles.

A headlight modulator increases and decreases the intensity of a motorcycle headlight fast enough that the headlight appears to flicker, or "modulate". The modulation of the headlight makes the motorcycle significantly more visible to other drivers. Higher visibility means increased rider safety. Headlight modulators are 100% legal in the United States for motorcycle use only.

A modulator can be installed to modulate either the high beam or the low beam. They are controlled by an ambient light sensor, so that they operate only during daylight hours, as required by federal law.

Because other drivers often don't see motorcycles, being visible in traffic becomes the rider's responsibility. Adding a headlight modulator is an inexpensive and easy way to significantly increase your visibility and your safety.

Plug-in Headlight Modulators

Splice-in Headlight Modulators

Plug-in Headlight Modulators are easy to install; they plug directly into your existing headlight apparatus. Plug-in Headlight Modulators are motorcycle make, model, and year-specific accessories.

Splice-in headlight modulators can be wired with any motorcycle and they're generally less expensive than plug-in modulators; but, as the name suggests, they do require wire splicing to install.
