Light testers inspect cans for pinholes and split flanges.
- Light shines on the outside of the can.
- A rubber stop prevents light from entering the open end.
- A sensor inside detects any light passing through flaws.

If light is detected, the can is flagged as defective, ensuring only high-quality cans move forward.
