My '92 has one "inner" bulb for the compass, there are "outer" bulbs for the other gauges, maybe that's where some the confusion is coming from. You have to disassembly the unit much more to access the inner bulb that lights up the compass. I have a spare compass bulb at home,still in the Mitsubishi parts bag, I'll get the # and post it for you once I get home. I bought 2 when my bulb went out earlier this year, you never know when a part is going out of production
