Standard Vans RV14 wing kit includes the cutouts for leading edge lights, lenses and lens retainer as others have said. It also includes a plate to mount a PAR 36 landing/taxi light and holes in the wing leading edge to mount this plate. The plate has bent ears on each side with plate nuts for mounting a retaining ring, which isn't included in the kit. I'm probably going to make my retaining bracket, because I haven't found one to buy that will work.
The NAV/STRB kit that is available on the order form is for the NAV/STRB in the wing tip only ($800). You'll still need a tail position/STRB for the rudder bottom. In the AeroLED form is the Sun Tail, which sells in the Vans catalog for $369 I think. ACS has the same 3 light combination in a 'RV Kit 1' for $1130. I bought this 3 light kit from Wicks at OSH for $1100.
