when i connect it to a regular 12v in the trunk (trunk light bulb or any other 12v) i get steady image and no issue.
does anybody know what may be the problem?
Mayve the reverse light is powered by PWM, but the other lights normally are too, at least the exterior ones as far as I know.

I can offer a suggestion though.

If you get a standard automotive relay, attach it to the reverse light for the "on" and to the battery / continuous on for the +ve.

That way it will turn on when reverse light is on and it will supply power form a steady source.

Hope that helps.
