As sonic bam has explained i need to prove to my instructor and an external verifier that i am competent designing and working with electrical systems.
My initial thoughts were to implement the automatic device into the anti-collision lights and the navigation lights. As far as i can determine from my research it is only mandatory for the navigation lights to be operational between sunset and sunrise. The device in question would illuminate these lights when the light levels fall below a certain level (IE poor light conditions). The lighting would also be on a three way toggle switch with on, off and auto options.
I didn't think of the cockpit lighting but that is without doubt an area to look in to. I was just cautious as it would be extremely embarrassing to present a room full of aviation professionals, with a design which has been in use for many years.
Thanks for the replies
