    I just installed these lights on my spreader, im thinking about buying 2-4 more of them to mount as well. Is it safe to wire these off of my spreader power?? They are 55watt lights, but also they are bright which is great.

    wire it to spreader power yeah if the wire is bigger, you could try
    how will you switch it on off? from in cab?

    or you can wire from battery in front to switch in cab then lights
    be sure have a fuse from battery to switch.

    No, especially if you have a variable controller in the cab. Best way is directly off the battery using a switch, fuse, and a relay. Using the power off the spreader is risky if you have a controler for the spreader.

    You could put them into a 7way trailer connector and plug them in to the trailer harness.
    I don't know what they are fused at, but i use a setup like this for 1 55w bulb on my backup circuit on my Ford.

    Think of them as work lites not salter lites. You use them when you load un load back up ect. so they are on more often than you think but once you have them wires to a switch you use them more often...

    I really wouldn't connect any of those lights to the line from the spreader controller. A 55w light will draw 4.6 amps at 12v, two is obviously close to 10 amps, and so on. I imagine the spreader controller is fused, if you add more current (amps), you could start blowing fuses. If you need some suggestions for wiring, let me know.

    You can wire them to the switch yes, but need a relay, or something to keep the power from pulling off the spreader motor.

    Might be better to wire that many sperate from the salter completely.

    Use a fog light relay available at any parts store. Use a lead on the positive leg of the circuit to trigger the relay. Switch the negative leg of the relay trigger so you can turn the light off when not needed. Run the positive power supply that you are switching ( with relay ) from the battery with a fuse in it.

    But with a variable speed electric spreader this would not work, because the voltage below full speed would not be 12 volts. So you could not use the spreader circuit on lower speeds to trigger the relay. You would have to just switch it manually with an electric spreader.
