I can't help with the driving lights sorry, but as for the plate lights, the light boxes are located just above your plate and have two hooks on each side holding each one up. You grab both ends and pull down and out (it's easier if you remove the plate first). Then you twist out the connector, pop out light and pop in new one, and reverse process.
Keep in mind though they are hard to snap back into place because of the wire so try and tuck it in and you get ready to snap the domes back into place.
