A while back, I happened to search the web for specs on bulbs, in part trying to answer someone's questions on an electrical issue. I have to confess that I have been lazy in calling out 1156 bulbs for side markers, license plate lights and rear markers. In the 74 FSM, Nissan called out the bulb specifications rather clearly. Type 67 bulbs should be used for rear/side markers, and type 89 bulbs should be used for license plate lights. I pulled up the 1156 specs today because I saw a comment
