I don't know if anyone currently makes such a beast, but I do know that they
once roamed the earth. The one I saw in operation (in the mid-'70s) was the
genuine article, as you describe.  I think its light source was a carbon
arc, but I wouldn't swear to it.  I expect that you wouldn't want to leave a
chrome in the gate very long...
