I am fitting the Whelan homebuilt special from Aircraft Spruce Part # 11-5600 (I
think). This gives
strobe, colour and white lights on the tip. The unit only draws a few amps of
current.

Drill a 15mm hole 10cm forward of the spar through the root core. This will
bring
you out
into the first lightening hole. Find some _very_ light conduit - I used
concertina
flexible conduit.
Make some supports from foam that you can distribute through the lightening hole
to
keep the conduit up against the foam. Apply 5 minute epoxy and bond it in place.
The flexible conduit
allows you to make the turn at the tip quite easily.

The Whelan units come with a multicore cable around 5mm in diameter for the
strobe.
You also need
a pair of wires for the lights.

No I don't but my web site has some photos which may help.

Run the conduit and like all good cablers install a draw wire before buttoning
up.

I agree. See and be seen.
