DIY Motorcycle headlight modulator

Building a motorcycle headlight modulator using a relay, an automotive headlight flasher, a photoresistor, and a few spare parts. These can be purchased commercially for $75 - $100. I built mine for about $6.

The flasher operates only during daylight hours. Once daylight is removed, the headlight goes back to constant. In this video, an artificial light is applied to simulate daylight, then is removed and re-added to show the changes. This is a test installation using a truck battery.

great idea, bravo!

i think that it would be better if the "amplitude" was a bit smaller, the light almost goes from full OFF to full ON intensity. it would be better (and less inviting for the police to stop you) if the intensity of light would go from, let's say 50% (the weakest point), to 100% (full). maybe adding a resistor in parallel would do the trick, but i don't know the scheme...
