I want to change the colour of the rear interior lights to blue, can I do this and if so where can I get the bulbs from?Can I change the colour of the rear interior lights of my mk4 golf?Technically, any blue lite on a car is illegal. In USA anyway; most other places too.
However, if the interior lite only comes on when the door is opened, then its OK. Make absolutely sure the lite is not on while driving.
I've seen different colors of bulbs at Advance Auto or Autozone, etc.
Or you could paint the plastic lens cover instead.
