A hard-to-find item, this power supply is perfect for vehicles that don't come with factory power outlets and is especially configured for motorcycles. The BikeMaster® 15-Amp Standard Cigarette Lighter Socket for Power Supply can be mounted either through a hole drilled into the body of your bike or with a bracket (not included). The power supply does come with a ground wire, so it does not need to be mounted to anything if you don't want to mar the body of your ride. Water-resistant, the power-in cables have rubber grommets while the power-out has a tight fitting rubber cap.
