BULB, 1004, LED, Clear, dual contact, 9 diodes, brighter than standard bulb, replaces U-L1004.
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.
