Easiest landing light install?

How do you change the bulbs? You can't replace the bulbs from the front, it has to be from the back of the reflector mount.

Thanks for the response. Apart from wiring, what about the structural parts? Can they be installed through the cutout? I guess drilling out the rivers is not the end of the world but I would avoid it if I could.

Yes you might be able to install the reflector with the build installed from the front but how are you going to replace a burnt bulb when the bulb has a set screw holding it in place from the rear?

The kit I'm looking at has the reflector held in place with two screws with washers into nutplates.

So, you'd unscrew them and pull the reflector out.

From the "Duckworks Landing Light Installation Instructions":
"Note that these instructions are written for installation in a completed wing."

(Hole in LE skin cutout instructions)

"When the cut-out is completed, it will provide all access to the wing needed to complete the installation."

All my installations (per DW instructions) are accessible by removing the lens (6 screws), than if necessary removing the 4 mount/adjustment screws and swiveling the mounting bracket around to get to the H-4 bulb if that style lamp was used. Kind of awkward but doable. If memory serves me, only one of my customer RVs ever had a H-4 bulb burn out.
For other lamps that I adapted (LEDs etc) I would create lamp bracketry that was accessible from the front.

Note these comments don't apply to later model kits. They employ different bracketry in the wing.

So you basically have to remove the entire thing (lense, reflector/mount) just to change a bulb? I guess yes it?s doable but not as easy as from behind like it was designed.

Like I said, 1 bulb replacement in the about 25 RVs with a H-4 bulbs over 18 years...
your experience may differ if operating off grass.
