BULB, 1004, clear, dual contact, index style base, 15 candlepower, rated average bulb life 100 hours.
A note about 67-68 Mustang Door courtesy lights in California: the California bulb U-L90 is only 7.5 watts where the non-California bulb is 12 watts. No Idea why the dimmer bulb was used in California cars but the U-L1004 and U-L90 bulbs are interchangeable.
