You can change the lights in the LCD temperature display to LED's. Blue or red look good. You need to select dropping resisters to get the 12 Volt supply down to the voltage and current ma specified for the LED's. Use wide angle LED's, not the spotlight type. I think someone wrote this up here once before. Go to the dealer for a new set of lamps, they're cheap. Since you have the VDO out, replace all of them.
