damn parking lights!

Greetings,

I have a problem here and I am stumped. Here it is; My parking lights do not come on anymore! I can't find a fuse that has anything to do with them. I looked under the hood at that fuse box and the other one under the steering wheel. All my blinkers work fine yet I still cannot get my parking lights to operate. This concerns me seeing as how I cannot drive at night because this outage makes it hard for others to see my rear. Any and all help is to be much appreciated.

Danny!
