Landing-Taxi light support spacers

The landing-taxi light adjustment scheme, involving a M4 bolt, spring, and two plates between which the light is trapped did not function correctly. The two plates would pinch together at the corners. The fix was to obtain 9mm long spacers - the thickness of the PilotGoodies light rims. These are from Wurth and made from nylon.

When finally mounted I will employ slightly longer M4 bolts and fasten in place with low-strength loctite.
