How to properly energize a tricycle billboard light
Just connect the light bulb to the positive and negative terminals of the battery.
Connect a wire to one of the battery electrodes, then connect this wire to the switch, the other end of the switch to the light bulb, and the other end of the light bulb to the car's ground wire.
The other electrode of the battery is the ground wire. Determine the thickness of the wire according to the power of the bulb. When used normally, the wire cannot generate heat. to avoid short circuit.

The transformer is AC and has no positive and negative poles. After rectification, the positive and negative poles are divided. When you connect the wires on the transformer, you should pay attention to whether there are multiple wires and the voltage value. Don't connect them wrongly. If there are only 2 wires, just connect them casually. If you know electricity, you can use a multimeter to help
