Basically what the question says, I want to get some coloured LEDs to install on the inside of my car, down by the pedals on the driver side and on the passenger side. I want to be able to drive with them on if possible. Is this legal? Also if legal, does anyone have any recommendations? I’m hoping to get ones that change colour and react to the music (I saw some before but can’t find them again). My cars a blue 2002 Mazda 323 SP20.
