One of my fog lights dropped out this afternoon and smashed on the road

I believe they are from a certain Sierra. I had a look on fleebay and it would seam that they are very rare to find

Does any one know where I can get one or know if anything else will fit? I was thinking about fitting a pair of cheap after market ones.
To top it off I ran out of fuel when the gauge was still reading half full! Then the battery went flat before the fuel got up into the carp. I bump started it down a nearby hill. Then 4 hours later I found I had lost my phone. I searched the house and rang it a few times before it when to voice mail (the battery was very low). I figured I must have dropped it when I jumped in the car while bumping it. I drove to the hill and the phone was not there. i got home and thought I would check the Rossa again. I have not heard id ringing before the battery went flat so was sure it was not in the car. it had dropped down the side of the seat. Thank goodness something when right

All I need to do now is find a suitable fog light and whip the tank out and find out what's going on with the sender.
