DIY Aquarium Moonlights
Add a blue moonlight feature to your aquarium! Get blue Waterproof LED grill light strips from an auto parts store. Cut off the end of an AC/DC plug. Put on gloves and be sure the plug is unplugged, then separate the AC/DC wires and twist the LED wires around each of the plug wires. Wrap the loose wires with electrical tape. Stick the lights on the lid of your tank or on another location where they will not be submerged in the water.
