If you're going to get it fixed professionally point that out to them and they'll address it during the repair. If you're going to do it yourself or just leave it then I'd start looking for a pinched or broken wire or a fuse that might have blown when the light got broken.
Consult your owner’s manual. There are several fuse boxes under the hood and inside the car and some components have combinations of multiple fuses and relays.
