Anyone put leds in there dome light??? I'm thinking this might give it a cool glow wwhen you push the button. I ain't sure what the lights called but the interior light above the gear nob. How easy would it be to do?
Are you on about the square roof light, the one with the 3 position switch that comes on with your doors and alarm?
If so, the bulb in there is called a festoon bulb and there are several ways you can change this from simply painting it or buying one ready painted to computer controlled LED's and LED festoons..
There are a few firms that do festoon replacements that use coloured LED's, some even cycle through different colours. I have got a GEM in mine from IceLed that when used in "stand alone" mode starts off white and then cycles through 2 million colours.
Here is mine before I rigged it into the programmable system I now have (have a look at the link under my sig to see it working)
You could even change the rear view mirror for one from an MGTF as this has 2 illuminations in it as well. These can also be changed for LED's as well
