Problem: My factory installed boost gauge won't light up.
I bought my '02 WRX wagon last April that came with the factory installed Lamco boost gauge on the column but the light has never worked. I just figured it didn't come with a bulb but recently took it apart and sure enough it does. I went to the local AutoZone, Carquest and O'Reilly's auto parts stores and only found a couple bulbs that were even small enough to fit the gauge but all were a higher voltage/wattage. The bulb reads "S .12V 2W". The only bulbs that were even small enough to fit were 1.2V 12W.
I bought the 1.2V 12W ones and tried them out but no luck. I don't know if it's the brighter bulb or something wrong with the wiring. Traced the wires under the dash and they are spliced into a connector that plugs into the under dash fuse box then out into a group of more wires. (Does this sound like it's correctly wired?)
I've read it can be wired off the dimmer on the back of the stock CD player/radio (which is still in the car) but was wondering if this is the only way.
Any help is much appreciated! Thanks.
