This Instructable will show you how to make an LED stick figure costume from LED strips and a power source. It’s a very inexpensive costume and should only take about an hour to make if you know how to solder. It’ll also keep your kid’s safe while they go out on Halloween night as they will be lit up and very easy to spot.
Here's a little video from this year's Halloween showing what it looks like in person.

Step 1: Items You'll Need

Black pants and hoodie
5 meters of strip LED lights in your choice of color(s). The length will ultimately depend on the size of the person wearing the costume but 5 meters is more than enough for a child.
Electrical tape (black is typical but I had both black and clear and used both)
9V battery connector and battery OR 3 Cell LiPo battery and appropriate connector (LiPo is MUCH brighter but is potentially dangerous and should only be used if you research the proper use of them. See HERE for battery care.)
JST connectors for connecting the pants LEDs to the hoodie
Soldering iron
16-20 awg black and red wire. The gauge isn’t really all that important as long as it is flexible. If you have an old computer you don't use anymore, you can take the power supply and raid it for wires.

Optional but very helpful:
Wire strippers
Helping hands for soldering
<p>I used a 9v battery concealed in the front pocket of her hoodie placed in a plastic bag, liquid Electrical tape to cover all soldered connections and hot glue to attach the light strips to the clothing. We had people commenting on the costume all night of trick-or-treating. I added a tutu with it's own LEDs and power source.</p><p>Great Idea!</p>
9V battery is always a good option. Glad it was a good project for you.
<p>Great costume! I used the barrel connectors from the LED strip and a splitter instead to avoid the soldering. </p><p> <a href="https://www.amazon.com/2Pack-Power-Splitter-Pigtail-Cameras/dp/B0186Z7P76" rel="nofollow">https://www.amazon.com/2Pack-Power-Splitter-Pigtai...</a></p>
<p>That's a pretty good idea as well. Nice!</p>
<p>Wich kind of LED did you use (5630, 5050 ...)? Thank you</p>
<p style="margin-left: 40.0px;">5630 and 5050 LED's are three LED's in one and use a lot more power. You can get various colors from them but they're more expensive as well. These were just a single color. I don't know the exact model number but the typical ones out there are the 3528.</p>
<p>can you use any other connectors besides soldering them?</p>
If you cut things up, you kind of need to be able to solder to get everything together. If you can find a way to string a really long strand together without cutting it, then you can get by without soldering it but it's necessary in this case. It's a good skill to learn too for other things!
<p>Congrats on this, I saw it last year and now I'm attempting it myself. Two things:</p><p>1. You used 1 9volt for the entire outfit, how long did it last?</p><p>2. Since that video, there have been newer versions of the LED strips. I have tri-color strips with a brain and remote now. I'm assuming this isn't the version you used, else you would need a 4-pin JST connector instead. Have you tried since this instructable to use these new tri color kits with the brain and such? If so, how do you power them? I just tried with an 8 in-series trustfire 3.7v batteries and to no avail. 1 9v battery however, does work, BUT, it doesn't seem to power the blue enough, so when I choose a white color, it glows gold/amber color. If I stick to single colors (Red, green, or blue) it works perfectly fine, it just seems like one 9v isn't enough to power all 3 LEDs all at once. Any input is appreciated, thanks for the writeup again.</p>
The 9V lasted an hour or so. More than enough to go around to all the houses but I may have also used a small 3S LiPo too. I can't remember.<br>I didn't try the newer tri-color strips. Are you sure it doesn't require a 12V supply? It's possible the blue LED drops more voltage across each LED. If you have three in series, which is typical of these setups, and each LED has about 2.5-3.0V across it, you won't have much margin for the voltage drop across the current limiting resistor. That could be why it doesn't do well.<br>If you have access to a 12V source, I bet that would work better.
<p>Good costume XD i love it+ congratz at being a finalist</p>
Thanks. It's hard to believe it's been nearly a year but it was fun to do.
<p>Congratulations on being a finalist</p>
Using 9V battery with 12V LED strip was a nice idea. It makes them safer and Longer lasting. Wish you luck. If you have space, also try 8x AA cells. Rechargeable ones recommended.
Thanks! It definitely makes the lights a little dimmer so they're not completely blinding and it can be much lighter that way too instead of carrying a larger battery.<br>LED's are by nature long lasting anyway and I'm not sure if using a lower voltage makes it last longer but who knows! It definitely is safer using a 9V over a LiPo battery.<br>I did think about using 8 AA cells but the problem with that is weight as that is very heavy. Using 8 rechargeable batteries gives you a nominal voltage of 9.6V instead of the 12V you would get with alkaline so other than for longer lasting lights, a 9V battery would work as well as 8 AA cells and would be much lighter to carry around.
Congratulations on being a finalist in the Halloween costume contest! Can&rsquo;t wait to see if you win good luck!
Thanks! We'll see what happens with the contest. It's not being announced for another week and a half so it'll be a while.
