I have a 1996 Jeep Grand Cherokee Limited and I wish to replace my low/high beams and fog lights with new bulbs, but I do not know what size bulbs are in it right now. They are all stock bulbs. I've been researching it online and I think the low/high beams are 9004 and the foglights are H4's, but i'm not sure

If anyone knows that would be very helpful

thanks!
