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.

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.

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.
