The "kit" version sold today is the same as the "kit" version sold 10 years ago. It could be built with or without the flaps at the builder's option. Ditto for any added lights. Mine has no flaps but I did add lights. The "ARF" version has only been around for about 5 years or so and has, to the best of my knowledge, always had flaps and lights, and only one version that I know of. Those are the only two 1/5 th scale Top Flite Cessna 182's ever offered. So, why don't you just download the kit manual and use it for reference ? What exactly do you need to know?
