I did keep the side portion of the old mounting plate where the Nav light is mounted. I figured why do more work than I have to re-fabricating everything.

I wanted to mount the new LED lights as far outboard as possible so they could get as much light closest towards the center line of the RV. It would be awesome if these lights could be used for both taxiing and landing.

I also needed a mounting plate for the light to mount to. The light comes with a mount designed to be mounted to handlebars with a single bolt at the bottom. That mount wouldn't of worked for me. I planned to use the 4 screw holes used to hold the front trim on. I made an appropriate mounting plate (pictured on the lower left).

I didn't think the front trim was necessary. I would replace it with my mounting plate made out of 0.063".

Here is a picture of how the LED light mounting plate is attached to the wingtip plate. This setup is extremely adjustable and very very study. I cannot more the plate at all.

These are the springs I used for the inboard adjustment points. I purchased them from Ace Hardware.

And finally the light mounted.

The light uses metric screws. I bought M4x10's which ended up working great.

And the final product. I used only a single light for a few weeks to test it out. I figured why should I spend twice as much as I needed to for a pair of them if they may not work out. I flew for about 10 hours with this, and it was on all of the time. There was ZERO radio interference, Zero GPS performance interference and ZERO NAV antenna interference. These lights seem to be very well engineered.

After my test of the right wing went so well, I purchased another set and installed it into the left wing. I have to say this side went MUCH faster. It's always easier to build something the second time.
