The current RV-7 and -8 wingtip design (W-715-1) has a comparatively huge light bay versus the smaller sizes found on all other models, so the light from The Works kit landing and taxi lights gets to spread in front of the plane nicely. The W-715-1 light bay is about 6" across on the forward facing edge, versus 4.5" inches or less on the -10/-14, RV-9 and the earlier "Batwing" wingtips.
The leading edge is the best place for landing lights to go, as there is no shadowing there and there's room for more/bigger lights as well. We'd advocate putting lights in both wings, so if your budget doesn't stretch to two Seven Stars you'd be better off with two of our Quad Spots instead so that you can see better down both sides of the runway and taxiways.
My usual sales pitch (using words from customer feedback) is that two Quads will give you Excellent light while two Seven Stars will give you Outrageous light. Your choice!
As mentioned above we have two different wigwag products, or if you're thinking about installing a VP-X, a Garmin GAD27 or a Dynon/Advanced Flight Systems ACM, these will wigwag /alternate flash the landing lights for you automatically.
