To connect a power supply to the lights we need to see which contacts in the battery holder are electrically connected to the lights. In the case of a 2 battery light string thay are these two at the top, which are soldered to the circuit board. The one with the spring is the negative, and the flat one is the positive.
See instructions below if you want to power multiple strings. To start, you need the 3-wire pigtail that comes with the LED light string. You can find the right wires by seeing how the connector attaches to the string. The wire with the dashes is the negative, the middle is the data line, and the remaining outside wire is positive.
To convert some old battery-operated Christmas light to work with a USB power supply we need: Battery-powered lights are pretty much all made the same way: they have a little box where there is space for the batteries and a circuit with the switch, and from this little box the wire with the lights starts.
If you want to connect a light strip with loose wires to a battery pack, just find one that also has loose wires. You’ll need to make sure it can hold enough batteries to power your strip – more on that later. Connect the positive wires of the battery pack and strip light together, and do the same for the neutral wire.
By using one voltage regulator we can also power multiple light strings running with the same voltage by connecting them in parallel, so - with - and + with +. When I plug in the power supply and turn on the light switch we can see that the lights work as before. Now let's see how to transform to work with USB lights that run on 3 batteries.
Battery-powered lights are pretty much all made the same way: they have a little box where there is space for the batteries and a circuit with the switch, and from this little box the wire with the lights starts. Generally 2 or 3 batteries should be put in the battery holder. Let's start with a light string that works with 2 batteries.
