I dont know but darn it, I am going to give it a try.
A friend of mine did exactly that. Many smaller aircraft use regular automotive lamps, so I presume you mean REALLY BIG 28V landing lights.
A second or larger 28V alternator and 28V battery is needed. Then you need a relay to turn the things on, since the switches you have won't do the job. When all this is hooked up...Boom! it's daylight.
Oh yes, put a basket on the side of your truck for the tickets you will get. When my friend did this he finally got a letter from his draft board classifying him unfit for service in 1964, since he had dozens of tickets.
