I'm wondering if someone can tell me if the the the 2 individual OEM cab light housing bulbs are replaced with a regular 194/168 bulb?. I know the center light houses 3 pc194 twist in socket style bulbs. The 2 individuals appear to be plugged into a connector that plugs into the main cab light harness. The connector is similar to the socket for the interior door lights. I think the bulbs are intended to pull out of the socket, but mine are very tight and I don't want to break anything if they aren't. Oh yea and I'm talking about the 2001-2007 factor roof/cab lights.
