The 4 little prongs are your ground.You can use 57 or 1895 bulbs.

Thanks. I figured that is what the prongs were for but didn't know if it would still ground if the housing is plastic that it pushes into. Good to know on the 1895. I have a few of those around so glad to know they are interchangeable with the 57s.
