Where can I find an LED key?

I just bought a pocket knife in the shape of a key and a USB drive in the shape of a key. (see pictures below) now i would like a little key-shaped flashlight to make my keychain complete. i would like it to match my other two buys. does anybody know where i can find one? i can’t seem to find it anywhere.
