Depends on the brand, JR red is +ve, brown is-ve, orange is signal. Futaba is red , black and white. Hitec is red , black and yellow. You can put the +ve together, -ve together and run the signals separate. You will need a 4 pins(conductors) connector for the servos. And the lights require a two pins connector. I would not run the lights with the servo power.

You really need to supply more information.
Will each wing have a separate molex connector or will both wings have only one molex connector?
Will you be using a separate power source for the lights?
Will you want to control the lights (on/off) independently?
What is the function of each servo in each wing?

Each servo (regardless of brand) has 3 wires : signal, +ve & -ve (also called common).
The lights (parallel or series) will have 2 wires : +ve & -ve

The +ve and -ve for the servos and the lights could be tied together. The signal wires for the servos could be tied together if you are simply using all the servos to do the same thing (eg, 2 aileron servos per wing). So the minimum number of pins on the molex could be 3.
However if each servo in each wing is for a different function the minimum number of pins on a single molex for both wings would be 6.

A diagram would make it easier to understand.
