I received these in a very timely manner.. The packaging was a bit light so the box was rough but the lights themselves were in great condition.The lights are well built and appear to be very durable.Time will tell.They are very easy to install.. And work great. .Very Bright and easy to see at a distance and in the mirrors.Only drawback is that they are made with the wire connectors installed on them. I had to remove the wire connectors to drill a smaller hole for the wires to run through and mount properly.Other than that you cannot miss with these lights.A few ideas for Nilight..I would like to see these made in Amber or Red only so they can be used in more than just the one middle position on a trailer.Longer wires and no pre-installed connectors.I do recommend the lights and plan to buy several more for my other trailer.
