That's my one beef with the SwitchPro. My LJ will be a backcountry rig for me, which means travelling back roads with very little traffic, but plenty of wildlife crossing them. Before I decided to go with the SwitchPro, I had set up my conventional switch bank so that there was one master switch for all the forward-facing lights (bumper, A-pillar, and light bar.) In other words, if I wanted two of the three on, I'd turn the master switch on, and then the two individual switches on. In most states, the lights aren't legal to run. With the master switch, I can quickly shut them off and back on when coming up on opposing traffic in those very rare cases.
The same cannot be done with the SwitchPro. They have a master switch option, but it's all on and all off (can't do two of the three). Oh, I can set up individual master switches for each combination, but that requires three switches (and remembering which one to press, which could take longer than the interaction with the other vehicle). Plus, I only have one spare switch right now. I called and requested they consider this for a future update, and it was not well-received. I could also wire a master switch separately, with a relay for each output from the SwitchPro brain box, but that kind of defeats the purpose of an all-in-one, solid state output controller. It sounds like I might be able to do what I want to with this SSV product. However, I like simplicity. While the LCD display thing sounds nice, I'd rather not rely on the LCDs continuing to work years down the road in order to use my switches.
