  1. will the dual harness work for using dual 50″ black label RGB while using them on the dual 50″led light bar brackets y’all have/ does this come with the RGB harness thats need for the RGB light or does that come with the RBG lights and if it comes with the RGB lights does this harness work with the RBG harness

    • No, this dual harness isn’t rated for 2- 50″ light bars. The BLL light bars each come with its own harness.

  2. will this harness work for a 54″ light bar?

    • Yes, the plug and play option might not match up but the rest of the harness will work fine.

  3. Can this harness be used for the 4pc rock light kit as well?

  4. Is the red light on the switch supposed to be constantly on? And if so won’t that drain my battery over time if the truck sits?

    • The light would take a long, long time to drain a battery. It is a led light and has very minimal draw.

  5. Quick question before I buy the double harness and before it goes off sale. I have 2 50″ bars and they just have the Red (Positive) and Black (Negative) wires coming from the bars. Would this work? or would I have to be doing some playing around with this harness to make my bars work? Also i have the OLB stacked 50″ mounts and the Strobe effect with “Key Fob” would this work inline or same thing have to do some modifications

    • 50″ bars need a high power harness, EACH. Also the strobe controller tops out at 400 watts. You will want 2 high power harnesses and also another strobe controller for the second harness and second bar. Hope that helps.
