Vintage Mego Batman Bat Cave Bat Signal LIGHT

Vintage Mego Batman Bat Cave Bat Signal LIGHT - dont have any C batteries unfortunaly and I think I remember putting 2 in a year or two ago and nothing happening so light is as is - cosmetically in pretty good shape with above average wear for a played with condition mego toy, few scuffs and scratches and dirt spots. issue might be the light surface rust / oxidation spot on battery terminal metal prong - Please see pics for best judgement of condition.
