There are two different designs, I have both types.. Push the battery test and a small lamp next to it lights. The other type battery test button lights the film counter as yours does.

The "over" and "slow" lamps should also light depending on the shutter and light conditions. You push the shutter part way down to see this.

These are very nice cameras with sharp lenses. The battery is the only fault with this camera.
