I got this bright idea, as it were, to add a backup light. I am a big fan of lighting, as previously discussed

, and there was a a nice space in the bumper on the one side (the other side having the license plate.)
On a street truck, I'd just hang the backup light under the bumper, but my experience has been that low-hanging lights get broken very quickly under the most peculiar circumstances (like driving up a friend's driveway ... crunch!) I also wanted to make it fairly easy to replace even though it was inside the bumper -- and it takes a fairly low-profile light to fit into a 2" deep space, I discovered.
In any event, I happened to have an extra single white light in my collection of fog and other auxiliary lights. (What, every CK5'er should have a box of extra lighting!) I pulled the bumper off and set about notching it:
Then welded the top up. The two holes have nuts welded in, to hold the top bar that was cut out.
That top strip then has threaded holes for the light bracket, and both can be easily removed without having to fiddle with the bumper.
I figure the bumper is still stupidly strong with the bits welded back in, and is certainly as weatherproof, etc. It's not cosmetically perfect, but I mostly managed to keep the rounded edges of the tube.
And here's an overall shot. Not a lot of space taken up, and tucked away nicely and safe from harm.
Finally, the money shots. The stock backup lights more indicate than illuminate:
That splotch would be my brown camo crewcab, parked about a trucklength back from the K5. Those are aluminum sheds behind it, of "Blazer: 1 Shed: 0" fame.
It's more easily recognized with the new backup light on:
Not quite night and day, but definitely a visible difference, which increases safety ... and gives me an excuse to weld stuff
Even more frightening is that this is with the stock wiring and there's only 9.5, maybe 10 volts actually getting to the lights

I have a scheme brewing to replace the lights in the back with LED's, so when I do that I'll also rewire some. The LED's may not need it (I'm looking at units that have current regulation and run on a wide voltage range) but I'll set up one or more relays for any regular light bulbs back there, including this backup light. I betcha at 12V it'll light up the night
