Hi all,

I got a quite a big project im gonna work on during the weekend. They are: running lights and PIAA headlight, big because I don't know anything about electronics.

I'm thinking, while I am at it, is it possible to install a headlight modulator with the PIAA headlight? Or do I need to have a special headlight? what kind of modulator would you recommend?


thanks +!

The PIAA HS1 SUPER PLASMA GT-X is a direct replacement 35W bulb. Nothing is needed. Just replace the stock bulb.

For the running lights, use Lil Buddy's wiring adapter (there's a thread in the for sale forum). I recommend using LED bulbs to avoid battery drain.

oh i know those, I am thinking about the headlight modulator, I am not sure how it works in terms of installing it.

will the headlight modulator comes with a bulb? Or do I stick the headlight modulator and then the PIAA bulb on top of it?

Most modulators are just boxes that wire in and alternate the flow of current to the light. Should be able to use with any bulb, I think. The specs for the specific model should let you know.

Depending on where you live, you may also be required by state law to install a switch to turn the modulator off after dark.

Yup, you'll have to have a switch to turn it off at night.

Motorcycles: Headlamp Flasher

25251.2. Any motorcycle may be equipped with a means of modulating the upper beam of the headlamp between a high and a lower brightness at a rate of 200 to 280 flashes per minute. Such headlamps shall not be so modulated during darkness.

Headlight modulators are legal here in California. You do need to rig a light sensor so it won't blink at night. Most people who run them say they don't shorten lightbulb life.Those who have never used one made up that myth. I just run the high beam in daylight 'cause I'm too lazy/cheap to install a modulator. I wired my own deadlights but the kit is easier. With 8000 miles on them I have had no battery issues with stock bulbs. My LEDs started going out almost immediately after they were installed.
