Video Transcript for Optronics Trailer Lights - Interior Lights - IL21CB Review

Today we are going to show you Optronics weather proof interior and exterior trailer utility light, part number IL21CB. This light features a replaceable lens and bulb. It utilizes a push button on off switch, a two wire design, a single wire for ground, and another wire for power as well as a foam gasket that will help seal out moisture. Its designed to surface mounting holes that are 3 inches on center. Now we are going to hook the light up to a power supply so you can see what it looks like lit up. Connect our power to black, and our ground to the white wire.

Next well turn off the overhead lights so you can see how bright it is in the dark. And that does it for Optronics Rectangular Weatherproof Interior and Exterior light part number IL21CB. .

They were exactly as illustrated and what we needed for our horse trailer. Also came at a nice price!! Would recommend shopping on their site 686815

Nice light even better install. I used two of these lights mounting them on thee inside of my salt shield of my snowmobile trailer. Turn the lights on and being able to see while tying the machine down etc in the dark works out great. No more flashlights. Lights are bright and don't draw lots of power. Recommend the lights and definitely recomended doing business with these folks. 452034

The "how to " instructional videos are excellent. They are very informative . The various subjects that are covered are excellent What a great Idea The opening video clip of the letter R falling out of place and the being driled back in place is a hoot. Thanks keep them coming, I will view videos on various subjects that I may not be working on but after viewing a video I can determine that I can tackle other projectsThe Videos are a Sales tool. 27207

Outstanding light! Extremely bright and very well sealed. We purchased this light for our boat to use as a utility light for night time fishing for stripers off of Block Island. It illuminates the boat great and beats holding a flashlight. Wiring hook-up was basic and love the fact that it comes with it's own switch. Will be purchasing another one for the cuddy cabin very soon! Thank you E-trailer. 14523

Installed 2 of these in a 6x13 cargo trailer. Could have used 1 more, but 2 lit up the cargo trailer nicely. Easy to install. 7887
