The truck can only use 24v, this light is 12v, so it is not compatible. If there is no problem with the voltage, just fix it in the place of use (there is a double-sided tape on the back of the lamp), connect it to power and it can be used.
If you want to connect a small amount, 2-3 strings, you don’t need to buy a wire. If you want to connect multiple strings, you need to buy the main wire yourself. It is recommended to connect them all in parallel, not in series.
