Testing pod lights without installing?

Is there a best way to test pod lights without fully installing. I’m selling a pair and the plug in doesn’t my fog light plug like the other pair

what’s the easiest way to light them up to confirm they work?

 

All you need to do is plug them into a 12v power source. You can connect them straight to the battery. I’ve used 12v drill batteries before as well. If you don’t have bare wires just make some jumper wires to connect the plug to the power source.

 

Thanks for the help. I have Milwaukee m12 tools I’ll try those batteries
