Nice! Thanks for the link, Mark.

My navigation lights for the Cessna 550 are the EDR-117 LiteSys from [link=http://electrodynam.com/rc/EDR-117/index.shtml]Electro Dynamics[/link]. This plug and play lighting system for scale models uses the ED-SunVis Wide-angle lamps that are visible in sunlight.

I'm using the LiteSys Starter System with Transmitter-controlled switching for $119. It includes the following items.[ul][*] Red and Green Nav Lights[*] Red Beacon or White Strobe (select)[*] 4-way Distributor[*] Landing Light[*] Dual RC Switch
[/ul]
The dual RC Switch can either turn the lights on whenever the receiver hears the transmitter or by a spare channel.
