Got a chance to try version 3.0 last night. This is purely a proof of concept design as it was made of 16 gauge steel which is way to weak for this application. 16 gauge is the max thickness my little bench top bender can do and was the thickest I could find in plate locally without costing an arm and a leg. The goal of 3.0 is easier mass production, better finish and better fitment. If you look at the picture below you can see the blank on the right compared to the finished bent version to the left.

Its very promising but unfortunately I can not continue this project to a mass production stage as I don't have the tools needed. I could contract out to local shops but I fear it would drive the cost of each product way up to a point where people may not be interested. These aren't copy written nor would I dream of doing so, so fab away my Liberty brothers and sisters.
As an update on version 2.0, the version I'm currently running, at highway speed, the lights have a little wiggle in them. I'm not sure if its the light brackets that came with the lights or if the mounts themselves are moving. Currently there is soft foam weather stripping on the back of the brackets to protect the paint. I'll probably sometime in the future replace the weather stripping with solid rubber once I measure the correct thickness needed.
I had another idea for version 4.0 using the black plastic trim fender trim sandwiched between two steel plates and riveted into place. The main concern with this idea is the strength on the plastic trim itself. It would be terrible if at highway speed the plastic trim or the plastic retainers break. There may also be an issue with clearance behind the trim and the fender. What does everyone think?
