I don't want to say this light tower has foolproof wiring but it's pretty close. While the wiring diagram seems to be universal for a line of products - showing 7 wires with 6 possible outputs whereas this version only has 5 wires for 4 outputs - it covers all the bases for the design. A nice little extra perk is that the wiring diagram included with the lights has a tacky backing strip - think strong sticky note - that you can tag the wire and avoid losing the diagram in the future.In terms of actual setup I particularly like that as long as you are properly connecting the "common" black wire to your power source, you don't need to worry too much about reverse polarity problems as the signal lines are set up to power PNP or NPN transistors to control the lights/buzzer. This worked just fine with the common cathode (-) or common anode (+) wiring. Not a lot of current draw - .01A to .03A draw depending on the signal used. These aren't 1W lights, so don't expect super bright but clearly visible in my well-lit workspace. Lights used inside the tube are basically double-sided LED strip lighting.The biggest downside is the relatively high voltage needed. A lot of the electronics I've been working with tend to use a 12v signal or less, so while 24v isn't out of reach (especially if you are already working with some LED light strips), you need to think about your power supplies if you're using Arduinos/Raspberry Pis or other variants of MCUs and single board computers. There are activation voltages between ~10V to ~15V depending on what color and lights you are trying to turn on. All the lights seemed to be close to full brightness around an 18v signal but don't rely on these to turn on with common 12v power supplies. You can of course power all signals in parallel and have them work together.It would be nice if the kit was a bit more complete - such as screws that fit in the mounting plate or tinned wire leads but overall this works as advertised and could be useful from safety features in a shop to DIY CNC equipment to components for a puzzle in an escape room.
