Led light. Various parts from Stuart tank.
This is a more real world looking HISS tank. An LED light was added to give it more visibility when necessary. Parts from a World War II M3 Stuart light tank were added, specifically the cannon and turret armor for the gunner's position, turret gun for the driver, and a rear gun port. Finally, it was covered with a dirty weathered rusty paint job so it didn't look pristine like it came fresh off the assemlby line.
