What is this hole for?

Hey everyone I have taken my truck off roading several times. usually when I come back my fog lights were full of water. I have taken them off and cleaned them out. I noticed there's a extra hole above the light in the housing that has a rubber stopper on it is this for an extra light?

Maybe if this was posted in the right area it may get more visibility. Mods move this to general
