Push & Turn style LEDs are not as common as 194 wedge base LEDs, but are often found in places where wedge style bulbs are normally used. The most common base is a ‘BA9’ style base which can be found in a few different variations – BA9S, BAX9S, and BAY9S. Each of these styles differ in the placement of the two alignment dots. BA9S alignment dots directly oppose each other at 180 . BAX9S alignment dots are slightly offset, and BAY9S alignment dots are almost right next to each other
