I want to add a multiple light bar controller. So far the options that I have found are SwitchPros, Spod & MLC-6. Are there any others out there that I should consider? What I would like to do is have a master switch so that I can turn the power on or off whether the truck in on or not. So, when the truck is on, all the lights have power. When the truck is off, there is no power to the lights. But, if I turn on the master switch, I would have power to all the lights when the truck is off. I would rather be in a lower price range than the SwitchPros and Spod. But, would pay that amount if I could do what I want it to. Any suggestions? And, I ain't equipped enough in the smarts department to to anything like this myself. No DYI please.
