automatic lighting
As long as installed, the roof color lighting will automatically light up when the engine starts!
The tedious switch operation after the engine starts is avoided.

Remember the last setup
The color and brightness of the last flameout will also automatically light up the next time.
For example, when the engine is turned off at 75% blue, the blue 75% lights automatically when the next engine starts.

Keep the pure function
Please switch the brightness to 100% 75% 50% through the room switch 25%.
Of course, with pure steering switch, ceiling switch operation is no problem.
