Well with out knowing the year I can't help you but on my 5th gen I painted all the gauge cluster blubs amber for the bmw-ish look. I used Krylon amber paint and it doesn't look half bad. I found out how to do it by get a shop manual for my 92 Civic.

Not to hard just use a lot of coats on the blubs.

If I redo it with this cluster or an Integra cluster I'm going to use LEDs. If I don't get a JDM Cluster of some sort.

This however is an easy, cheap and good looking mod.
