Repurposing Christmas lights

I’m not going to get into posting a commentary about the election. I’m fairly confident that, by and large, things in this world have reached a point that playing musical chairs in Washington won’t do much to change the path we’re on. As Kosh pointed out, once the avalanche has started its too late for the pebbles to vote.

This isn’t to say I’m one of those ‘If voting changed anything they’d make it illegal’ idiots. I vote every chance I get. While it may not make much of a difference in terminal performance it might affect the exterior ballistics a touch.

And before I move from the topic, let me leave with a joke: Did you hear the one about the Illinois Democrat who said that when he died he wanted to be buried in Chicago so he could remain active in the party?

My wife, sadly, like many wives, has a ‘crafty’ bent that can only be appeased by sacrificing greenbacks on an altar at the local Michaels shop. I go with her to help keep her under control but also because, if youre creative enough, you can find something preparedness-related in pretty much any store. One thing I found of interest was a string of tiny LED Christmas lights that ran on 3 AA-batts. Something very similar to thisproduct. My planned use was to splice the wires to an old solar panel that was used to charge some yard lights and use the string of LED’s to illuminate the house numbers. However, I discovered that these are excellent lights for odd places that dont require huge amounts of light…like the interior of my gun safe. Affixing them inside the gun safe around the interior of the door frame lights things up perfectly. I’d like to mount a photoresistor or pressure switch to turn them on/off when the door is open/closed, but they appear to do a nice job of showing me where things are. Since they run on three AA-batts and LED’s draw low power, its not too hard to imagine some useful emergency lighting options…most notably to light a pathway to emergency gear…much like the lights on the floor in the aisle of a plane.

I’ve seen pictures of peoples storerooms and basements where light ‘ropes’ are used to provide a sort of emergency area lighting and it seems an interesting idea. Most of the ‘ropes’ you come across this time of year (CostCo and WalMart are full of them right now) run on household current but use a 12v transformer, so you could, I suppose, just run them right off a DC power source. On the other hand, since my use would be for emergency lighting to guide me to my stash of gear, they could be considered a ‘one time’ use item. That is to say, in a hypothetical scenario, the power goes out and I’m standing in the dark. I hit the Big Red Button and five or six of these daisy-chained lights light up guiding me to where I keep all the gear. Since all the strings are running off a battery pack meant for one string they’ll remain lit only for a brief amount of time….but by that time I’ll have gotten to my gear where my other illumination supplies are. I suppose I could use a larger battery pack but then I’d have to get some resistors or something in there to keep from putting too much current through the LEDs and burning ’em out. Should be an interesting project.

  1. I have seen the old style rope lights burn out in a possibly dangerous way when used for extended periods of time. The LEDs are a much safer proposition. Obviously even better if you can find them cheap. Since they run on dc and you can put them on a dimmer, I am not sure that you have to have a specific size battery to run them so long as you don’t go over the voltage limit.

  2. I use Maglite 3D flashlights mounted vertically in snap-in plastic Maglite wall brackets. In a bracket you always know where the light is, aimed up the light reflects off the ceiling which is usually general illumination to find things, and you can grab the light out of the bracket and carry it with you. D cells are common and, in bulk, cheap. Multiple flashights provides redundancy. A pair of brackets in a closet or storeroom allows placing a flashlight from somewhere else in the house in the bracket for general illumination.

    • I’ve used those brackets in the past but I’ve found them to be breakage prone and very brittle. Although I do still have a few in use, I’ve mostly put my MagLites in the Night Ize sleeve. This lets me just hang them from a hook or nail on the wall.

      • A little bit of careful work with a drill press (or Dremel) puts two shallow opposing holes in the base plug of a large Mag lite, at which point you can snap in a wire D-ring (which is the sort of thing Mag shoulda done on their own, and probably would have if the former founder’s ex-wife hadn’t taken the business in the divorce, at which point product innovation pretty much went out the wazoo).

        If you aren’t worried about pretty, and just want quick & dirty, a single hole through the base, insert machine screw eyelet, apply nut inside with a dab of removable Loc-Tite and some silicone caulk, and you have a handing ring/lanyard loop that’s pretty bombproof and water-tight. Some Krylon rattle-can black and it even matches the light body.

  3. I don’t go near Michael’s, and don’t comment on her trips there. She does the same for my frequent Cabela’s trips or MILSURP purchases. It keeps the peace.
