    That sounds even better.

    So, I would like to run them from my light bar, facing back(obviously). So that I can see when I'm headed out to the deer stand. Any other ideas on placement?

    Underneath the bumper is always a nice spot that's where mine are. They are wired to a switch right now. Eventually getting them to turn on with my reverse lights since mine are useless

    Under the bumper freaks me out due to the risk of shaving them off while off-road. But without putting them on the bed rails or obstructing my cargo area it seems like the only logical spot. What do you know about running a secondary battery for toys like a winch, lights, cooler and a power inverter?

    Did you have any updated pics of this that are not on photobucket?

    I'll work on getting some up direct-hosted. I'll also draw up my improved circuit and get it posted.

    The reasoning for me putting them under my bumper is lack to put them anywhere else. I have a suburban, and I don't yet have a roof rack I can hang them off of. Besides, reverse lights are typically mounted low, and that's the primary function these serve for me: auxiliary reverse lights.

    Apologies for not getting pics up yet, but since most the whole setup has changed since I did this write-up, I'll get some new pics and post them. Still have to draw out the reverse-light trigger setup too.

    I completely forgot to take pictures of my latest setup today, but I just drew up the wiring diagram that will allow the lights to either get automatically turned on when in reverse, forced off, or forced on. I omitted fuses in the diagram, but any feed from a battery source should be fused. Here's the diagram:


    The single-pole, dual-throw switch (SPDT) is key to this setup. I use it in reverse of the typical usage by using the common to feed the positive side of the coil and the 2 switched legs as my source. If you want to set it up as ground-switched, swap the battery-fed leg of the SPDT switch to the ground and put the other side of the relay coil (85) to positive battery and the reverse switch input to a ground-switched reverse switch.

    I took a couple pics of my new setup. The switch and relay are still not hooked up right or mounted where I want it, but I haven't gotten around to fixing it right. I swapped the lights out for a smaller pair of driving lights I got from Walmart for somewhere between $20-30. They work much better and are smaller to make it easier to hit or knock them so they don't get misaimed. They're about as tall as the trailer hitch, so if they get knocked, I'm dragging the hitch.

    Here they are:


    Switch just hanging off the center console:

    Relay under the hood; I still haven't put in a fuse holder yet, so the main feed is not connected right now:

    I hope to upgrade my wiring with some nice fuse and relay blocks in the future, so it'll look better then. I'll also be putting the switch where the factory radio goes.

    I've been thinking about cutting out holes in the rear bumper of my new truck for a set of reverse lights, it's already real low and after launching my boat a few times I noticed the bottom edge goes in the water at times, and I'd rather not dunk the lights while launching.
    My old truck had a light bar/high lift jack rack behind the tool box facing the back so the lights were high enough to give a good pattern.
