Ohhh lol, misunderstood what you meant by multi-colour
It's a bit of a pain in the ass to change the globes, I got blue and want to change to red (bought new gauges that illuminate red so now it doesn't suit), but I can't be arsed. I found it damn annoying because first you gotta get the dash out (not hard, takes 5 mins), then putting in the bubs is guesswork because if you get the polarities wrong then they won't work but they don't have an indicator as to which way they should go. So you have to replace all the bulbs, refit the dash, turn the lights on to see if they work, note which ones don't work, take the dash back out, switch the bulbs around, then do it all over again.
It's not hard, but it's damn frustrating. Especially when the FUCKINGSHITCUNTSONOFABITCH wiring looms in the back of the dash refuse to come out and you bust your finger open with a screwdriver trying to lever the bastard little clips :rant:
