Make sure that the switch is up to the job of running both lights off one
side. You may want a relay somewhere. You don't double the CB rating
either. The CBs are there to protect the wiring and you have two wires
going to different places. If you go to one CB, it has to pop if *either*
the L or R circuit shorts. You could use a single 20A CB if you use heavier
wire from the CB to both lights.

I'm in the midst of having these lights installed, (they are the
cut-in-the-leading-edge landing lights) and we come to a fork in the road
with regards to the wiring.

The kit comes with a split L/R on/off switch, and two 10 amp circuit
breakers. This means that my existing landing light switch stays in the
panel, controlling the nose light only, while this new switch has to go in
the panel somewhere, separately controlling EACH wing light.

IMHO, this is stupid. Why would I *ever* want to turn on, for example,
only the left landing light? My idea is to replace the existing landing
light switch with the new split switch, and put the nose light on the left
half, while putting BOTH wing lights on the right half of the switch.
(This would require a 20 amp breaker on the right half of the circuit,
instead of the 10 amp that is supplied.)

My A&P says Skycraft's STC doesn't cover that option, and he would have to
get a field approval, blah, blah, blah. His idea is to remove my pitot
heat switch from the little "bank" of switches on my 235, and install the
new split landing light switch in its place. This will put it right next
to the existing nose light switch, so turning on the landing light(s) will
be almost as simple as it is now (or would be with my idea).

The pitot heat switch would then be relocated in the plane, somewhere.

This is obviously better than installing the landing light switch in some
awkward place, but it still seems goofy to me.

What do you guys think? Anyone ever installed these things? What did you
do with the switches?

Thanks!
