I already have my c-lights installed but I need to rebake them so that i can remove my broken halo lights and replace it with new ones. Will rebaking my headlights damage the c-lights that are installed?

Check out the manufacturer specs, or if not available then reach out to them. It's been a long long time since I baked headlights so I don't even remember what temp they go in at.

It's only like 200-240 degrees Fahrenheit. Not hot enough to melt plastic, just heat up the sealant. So I doubt it's going to damage your c-lights.

If you are worried about it you can always use a heat gun instead so the heat is more localized around the sealant.
