head light modulator

[RICZ]

Let us know how it works. I stopped at my dealer looking for a modulator for my rtl. He said he never put one on a Spyker and was a little worried to attempt it

Many modulators are plug and play simple to install. Put it on the low beam.

Here is a short video for a headlight modulator. This video starts out with a brake modulator that flashes 5 times then goes steady when the brakes are applied. This draws awareness of following drivers that something is happening in front of them. The headlight modulator draws attention to the bike coming at them.

Thanks for the video. Deanna

My $.02. I had Diamond Star headlight and Back Off brake light modulators installed on my last bike. They absolutely work, saved my life a few times. I finally taped the sensor on the headlight off as I was embarrassed by people thinking I was an emergency vehicle and pulling off. I think they work so effectively because of the change or movement of the lights, front or rear. In this day of cell phone distracted drivers, some of them see the light change or movement when they're on video induced autopilot. Kind of drills into their subconscious.

Technical guys out there, let's take a swag at these questions;
1. About 8900 miles after installing the modulator I lost my engine ECU. My bike had a halogen headlight, large amperage draw. I always wondered of the cycling of the headlight D/C amperage set up an undesirable A/C flicker in my D/C system, which can be bad for electronics. I did measure for that, and did see an increase of A/C present in the D/C circuit, just not technical enough to know. Though an appropriately sized capacitor would help.
2. Legal implications of turning it off. I had considered adding a switch, but in such a manner as it could only turn the unit off, but not on. This should ease the problem of manual switching of the function. Mount the sensor as prescribed by the manufacturer, and add the switch to one leg of the circuit. This is based on the assumption that the ambient light sensor either sends a voltage reference or closes a circuit (NO circuit). Never did finalize the research on mine though. Procrastination is a terrible thing!

I would say possible, but not likely. I never had a problem on my Goldwing and have never heard of pulsing of the headlight causing damaging AC.

Some modulators come with on/off capability to turn them off during daylight. None of them can be turned on in darkness, except if a street light is bright enough to activate it! That has happened to me a few times. The photocell works by closing the sensor circuit like a switch. The sensor circuit must be closed for the modulator to operate. You can add a switch to either leg of the sensor circuit so when you open it the sensor circuit stays open, or broken, and keeps the modulator from operating. That's what I did so I can turn it off when advisable to do so.

RICZ the dealer was worried about the ecm picking up the modulation and throwing it off, he said the Spyker are too smart. He did look on this forum for guidance but didn't find anything definitive at the time

Here is a clip of the Spyderpops LED Bumpskid with the remote control. This setting is my basic daytime running, at night I set the remote to have the LED's steady on and drop the brightness to 25%.

I asked at the police office and they said as it just going bright to dim, not turning on and off, (i.e. not flashing) it is the same as a headlight modulator.
