Short circuit security light

Hello there

I was testing one of our security lights tonight with a fuse tester screwdriver, and by mistake I made a short circuit and I think the main fuse for motion sensor light is tripped(blown). Except the security everything else is perfect. I asked the owner of the house and she told me that she can not remember to see any fuse for that. So, I was wondering if you could kindly let me know how I can our security lights. If you need more information please let me know.
