Hi All,

I have this small problem. I've bought this small battery operated bicycle LED light similar to the attached but with clear plastic case and with 3 color LEDs like police lights does. Mounted it on the handle post by the way.

It works well when the motor is off and pedaling, but when the motor is on it does not light even when I press hold the button.

I assumed the motor has some kind of interference on the circuit or something, so I tried to shield it somehow with electrical tape and aluminum tape underneath the circuit board but still the same.

Maybe you guys know some solution on this. I have a similar one on the rear, red light and it's working fine.

Thanks guys! pino.

looks like the CDI is the culprit. Tried holding the light on, when I get it near the CDI it lights crazy then off.
