Twist-in bulbs for instrument panel

azaustin: The bulb in your photo is not a #158 bulb.It sure looks like the #57 bulb that fits the old style black plastic socket.Take your bulb to any auto parts store and compare it to the #57 and #158 bulb.The problem is no one manufactures the old style socket anymore for the #57 bulb. Redfish has the best solution. Just use the readily available 2496279 socket and the #158 bulb.
