WHICH WIRE IS HOT. THE RED OR THE BLACK?

I had the same problem. Except my lights came with blue and white leads....After searching a few forums, I learned that they will only work wired correctly; meaning connected correctly, they will come on, wired in reverse they will not light up. I tried them both ways and found this to be accurate.

black wire is a ground.. common sense says black is ALMOST ALWAYS negative/ground.

you have to find the wire that runs the day time running lights and connect the red to it. the black wire is the ground wire.

The black goes to ground the red wire goes to positive on the high beam. You have to find the high beam wire first. Good luck.

its actually 2 wires that must be spliced in. 1 red (power/hot) and 1 black (ground).

The blue wire is the hot and the black wire is the ground. Not sure which one of yours is hot and which one is ground. You can test them to see.

I really don't know if there is any difference between the black or red models I have the black and I love it I wouldn't trade it for the world,it's the best as far as I'm concerned.

Your power supply would be considered the source and your radio is the load. Red is hot and black is ground from a DC power supply. Same on the load side. Will not work with a AC power requirement as far as I know.

Thee red is for 240 volt , the black and white are for 120 volt . Most likely when you remove the old emergency light it will be white wire to white wire and black wire to black wire. if you see a red wore comeing out of the wall or ceiling just use the red wire in the emergency light and place a wire nut over the black wire in the new emergency light.

The red button is to choose heat level (cool, temperate, hot) and the black button is level of power (high/lo).

The red, usually upper button is power, low, and high. The other is cool, warm, and hot.

I believe the Black/Infrared is the black+red pair. I'm assuming Amazon sent me this question because I purchased that pair, and reviewed it, but it looks as if the site may have changed the picture since then.

The red and black are power 8-15vdc and the yellow is RPM/tach; you don't use the yellow wire to run the fans, I cut them off.

on my set one is red and the other is black. If you hold up the left headphone with the ear piece pointing away from you the wire will bend off to the right.

Red wire has to have a constant 12 volt supply the black is ground so you can ground it to the body of your vehicle or any other ground the orange is a floating ground meaning that you connect to your accessories power source e.g your deck so when you turn your ignition swith of and your deck comes of it activate the scanner make sure you put a fuse on the red wire

I'm not sure but I can say that it is black in color and heavier then the standard wire that I received with the kit. Hope that helps.
