Before you go to all the work to patch the landing light cutouts (which will probably never look quite right), here's some food for thought. I've observed both an RV-7A and RV-10 at night with the landing lights integrated into the wingtip, and there were two things I did not like about them:
1) With the landing lights on, the nav lights become much less distinct...I noticed the red light in particular ended up looking sort of a pale pink color. There's just so much light being output by the landing light, including a fair amount of internal reflection off the plexiglass lense, that the nav light gets overwhelmed by all the white light. The strobes also looked less distinct.
2) The wig-wags are less distinct when blended in with the nav lights and strobes, and they are also effective over a narrower angle ahead of the aircraft. This is because when the landing light is in the wingtip, a portion of the tip protrudes ahead of the light and reduces the angle at which it's visible in the direction inboard from the light.
Bottom line is if you keep the landing lights in the leading edge cutouts as designed, you'll save yourself some work, your aircraft will be more visible to other aircraft due to the more distinct wig-wag effect, the wig-wags will be visible over a wider swath of airspace reducing chances of collision from your left or right, the strobes will be more visible, and the nav lights will be more effective in communicating the orientation & direction of travel (as intended) to other pilots.
FWIW...
