McGarrett is correct. Those are oil lamps that were mounted on the side of a Model T before electric lights were available, around 1915. Although this is a later Model T, so they were adopted from an earlier car.
This is what it may have started out as - Model TT trucks never changed much visually from 1917 right thru the 20's. The cowl lamps mounted on the front are not Ford I don't think. The other dark thing on the fender appears to be a mirror to me.
They could be anything. This is a cobbled together vehicle for promotion, after all. Advertisers care little about facts so anything goes. Could even be fake buns.
