If you wanted wiring for each function on all of your bars and lights, you would need a multi-trigger harness for each light. The Radiance Series lights only come with wiring leads with two positives for the backlighting and main lighting, and a negative. Now, to avoid having a berjillion switches floating around your truck, you will need to get tricky with the wiring. According to Rigid, the Multi-Trigger harness can handle up to about 23-24 amps, so you could just purchase two of them, and use one for your 50" bar and tie your cubes and your 10" into the second. Then what you could do is tie the switch wiring for both harnesses into just two switches (one for backlighting, one for mainlighting). You can also do any other combination, but it would take custom work, unfortunately.
