I saw this posted on a German facebook group

A Mk4 Golf stereo, which is usually blue and red backlit, that has had the LEDs swapped out for all green.
Personally I think this looks great. These stereos can be picked up pretty cheap, looking at eBay they're mostly under £30, or about £50 if you also want the 6 disc CD changer.
I'll just leave this here for comments.....
I'd love to know where you can get the LEDs swapped out.
Would 100% do this for my red one and then retrofit bluetooth to it.
