The cover has several retaining clips, you have to CAREFULLY pry it off by releasing the clips with a very thin flat screwdriver or something similar.

I turn my dome light off and rely on the purple cold cathode tubes I mounted under the dash.

I probably will look around for purple bulbs for the dome light itself, but I'm not in any hurry.

I will be adding a cold cathode tube to the hatch area as soon as I get another ballast for the extra I bought.

Lastly, I'm waiting on 1" Purple EL tape to replace the stock blue in a set of illuminated sill plates I bought. So that's going to be another thread when that arrives. (tutorial and pictures).

Cheers!
