Ya. The lighting is not part of the cruise system itself. Normally both dont go out though if its a lamp issue. It could be a sign of a bad clock spring thought, both paddles will go out then. Try the horn and see if the cruise does start to act up.
If you do need a new paddle set, let me know. I have a source for new OEM for cheap, I think around $20 for most colors. If you need a clock-spring, they may have that too. If not Jamie would have a used one I am sure.
