ImaginaryColours.com presents an instructional video on how to properly install the slide-on type of plugs on your custom light strings. This is an important video to watch. Many people put plugs on incorrectly. The funny thing is, if you connect the wires backward, the lights will still work. However, you will have inadvertently disabled the inherent safety mechanism provided by the Neutral conductor.
NOTE: If you are not experienced with electricity, we recommend you have a qualified electrician do all your electrical work. We at ImaginaryColours are not electricians, and we provide this information and believe it is accurate. However, you mess with your electrical stuff at your own risk!
