John Mc - perfect timing for your question ? let me first start by saying my build is going to be E-AB and not E-LSA. I?m in the process of adding a landing light to the left wing. My left wing skeleton is completed but the wing is not skinned yet. To help alleviate the aforementioned audio noise issues, I?m running 20 gauge three conductor shielded wire to both the landing and nav/strobe lights (AreoLEDs recommends shielded wire for the nav/strobe but they had a 50? minimum so decided to use it on the landing lights as well).
The left wing?s electrical connector will accommodate your needs, but will be maxed out. The ground, stall warning, and nav/strobe wiring consumes 5 of the 8 contacts leaving three available?and that is what you will need for the landing light power, wig wag power, and the master to slave (think wig wag sync) wire.
I also will be running the Tygon tubing for the AOA feature. In my case, this requires kicking up to larger wire grommets for the eight ribs the Tygon will pass through. I will be using Heyco SB-437-5 grommets (available from Mouser) which have a wire hole of .312" in the eight ribs the Tygon tubing will be running along with the two shielded wires. It requires going up to the next size larger hole on a step drill to 7/16?. For the rest of the ribs, the grommets supplied by Vans could work but it is a VERY tight fit for the shielded wires (and forget about pulling in another wire) so I will likely use Heyco SB-437-5 grommets up to the landing light and Heyco SB-437-4 grommets, which have a hole size of .270, for the remaining grommets ? the mounting hole size for both grommets is the same ... 7/16?.
I do not plan on doing any night flying, so will only use the left landing light in the wig wag mode. That said, I will run the wire to the left light?s steady on power (red wire) through the wing and should the output of the Rotax electrical get increased in the future, I can tie the wire down should I decide to night fly and want the light. I suppose a switch could be added to only power up the additional landing light on short final to keep from over taxing the system for a long period of time.
I called AeroLEDs and verified that the total current consumption of both lights in the wig wag mode is the same as one light steady on ... and it is according to them. For wig wag operation all that needs to be done is wire from the right light?s master out (green wire) to the left light?s slave input (blue wire) and have power applied to both light's wig wag power (yellow wires). Note: For wig wag operation, power is NOT needed on the steady on (red) wire and if power is applied to the wig wag (yellow) wires it overrides the steady on power and places the light in a pulse or wig wag mode depending on a one or two light instillation.
Hope this helps,
John
