Our LED light kits are among the easiest to install. Any 12v accessory requires connection to power (and ground). We feel like most products that make the “Plug and Play” claim are misleading at best, and many are actually harder and more limited to install with completely unnecessary harnesses solely for forcing you to use specific components, ore example, or worse. All of our ProGlow line strips, rock lights, and whips connect to the controllers with simple waterproof barrel connectors; simply press them together and twist the collar tight.
