Rear light wiring

Name:  image-3182508436.jpg
Views: 63
Size:  357.1 KB I wired this light as my back up light but I would like to use it as a work light or convenience light. Any idea how I could wire a switch to it so I don't have to leave the ignition open with the shifter in reverse? Maybe a diode wired inline so I don't get any power going back to the reverse light switch on the transmission.

I suppose you could use a diode, but I don't think it's necessary, there's nothing to backfeed really.


I'd simply run the light off of your reverse switch and then tap a secondary switched power source to the same line.

Ya got me thinking about this... it would be fine unless he somehow is using that light and activates the reverse at the same time. At that point he's bucking power and it's going to blow both circuits.

I guess if he brought both sides of the reverse switch up to a toggle that would work, as long as a second circuit is not introduced. Not sure if that's what you meant by secondary.

Nah, I've wired mine the same way on the jeep and on my fullsize... no issues

I'm just gonna wire in a diode. I found an extra one I had from when I wired my existing lights to use when flat towing.

The voltage doesn't add to itself from multiple sources, the most you can get to the light is 12v. So, even if the switch is on and you shift to reverse you still can't get more than 12v.

Simple spdt (single pole double throw) switch On-Off-On. Left from Back up light switch, Center to the light and Right from a constant power source. One position is backup, center is off and the other powers it up as a work light.

This is true, you wouldn't get more than 12v but... two different 12v sources (circuits) contacting each other won't play nice.

Why? They both come from the same battery through a switch to the same return ground path. If both are on, the only thing happening is you have effectively increased the wire size.

I'm thinking of it like a water spigot, if you have a "Y" fitting at the spigot and run two hoses off of it, then "Y" the two back together later into one hose you're getting the same output whether one or both sides of the first "Y" are on.
