Review on 💡 Enhanced Performance: Waterproof Illuminated DPDT On-Off-On Rocker Switch - Double Pole, Double Throw - 3 Position by Aaron Schultz

The light doesn't work when you follow the instructions. Nice switch once I figured it out. Take 1B to 4B and 2B to 5B and you need to connect ground to 1A and 5A if you want the bulbs to light when the switch is turned on. Be very careful when cutting the hole for the switch. Make sure the corners are rounded or holes are visible in each corner of the switch. I would give 4 stars if the instructions were correct. Too expensive for this switch.
