The compass bulb is available from your Mitsubishi dealer. Cost me Php75.00. Probably cheaper in El Dorado. It's called a CONSOLE BULB. The bulb and the socket are sold as a unit. But the parts counter guy seems not to know about it. At least they had the parts book [and my busted bulb] to help the search.

Pretty easy to install. The center cluster can be taken out by just unscrewing the two screws on either side.
