Can you change the colour of dash lights from yellow/orange

Yep, it has been done though it's not easy and requires you to be very handy with a soldering iron and have the patience of a saint. If I get a chance I'll try to dig out the thread on it.
 
That looks amazing. What would you need to try it yourself? Or is that a long shot?

Very steady hands, alot of patience, amazing at soldering, lots of soldering equipment, and the correct LEDs haha, and to have the time to do it all at once otherwise you'd be without everything for a while, you could still drive it I suppose but its a little illegal :smile:
 
How long did it take them to get it back to you? Yeah it would be illegal even if you put a temp dial in because the mileage is stored in the speedo not ecu
