Do you use the dimming control?

I have just watched the video, I have not see this before.

Please try the following:
1. Relocate the red wire (molex) to th ebattery directly.
2. test it for flicker
3. Relocate the red wire of the grey connector to the battery (ensure the engine is running)
4. test for flicker.

If it persist, I will send you a controller, I would love to see what causes it. Thank for the discretion. Nowaday, competitors are so keen to take things out of context for the purpose of negtive marketing .
