When I ripped the dash out of my 3rd gen this summer I took a look at the cluster. I noticed that the original bulbs were 3W and someone had removed the green covers. Even with no covers they were pretty dim. I thought about blue or red lights for the gauges, but then I realized that I could not change the color of the switches. So I just bought some 5W bulbs and green covers and put the thing back together. Now I have proper lighting in my gauge cluster.
I also put a cover on the bulb for the heater controls and replaced the bulbs in my hazard switch and foglight switches. I even put green covers on the bulbs in my pyrometer and voltmeter. My GPS also has green backlighting so my dash has a very uniform look to it, and the green does not irritate my eyes at all. Even the 12V charger for my cell phone has a green indicator light.
Too bad my headunit has red lights, I might have to take lighting into consideration the next time I buy a headunit.
