Trailer Light Testing

Описание: Using a 12 volt battery to test your trailer lights. It is not very convenient to hook up your vehicle when fixing or building a trailer. This will make it easier. It doesn't have to be a vehicle battery, any 12 volt will work, such as an atv or generator battery. I will be doing a video at some point on building an enclosed box for testing, using an ammo box. For now, keep Grinding.
