It is ok to have any lights on the car as long as they are solid, cannot be seen, and do not draw attention to your car to put anyone around you in harm….The pink license plate frame would be a definite no in this case….As long as your light source (The tubes) are hidden then there will be no problem…You can run any color as long as you do not have red or blue facing the front and visible….As for the wheel well lights as long as the source cannot be seen when lit they should be ok, but be careful because if the light is behind the wheel enough it will look like it is “flashing” and you will be ticketed for that….
