Cool LED Night Light




About: Jack of all trades, master of none. Father, husband, creator.

This is a simple yet effective little night-light is loosely based on the Solar LED Light Jar.

It took me about an hour to make and works great when dark. I apologize about the photos if they are not the greatest, my camera and I are not getting along.

Caution: This instructable involves broken glass, please be careful, I am not responsible for any injuries. If you are a "young one" please ask an adult for help.

Step 1: Materials

You will not need much to complete this project. I got the LED from a lighter (neat) but you could use any one from a key light, toy, etc. The important thing is that it has a attached power source. You will also need the following;

Glass Jar (what ever size you wish- smaller the better)
Rocker Switch
Broken Glass
Utility Knife
Soldering Iron

Step 2: Whatch You Fingers

First, cut a hole in the top off the lid the same size as the rocker switch. It was thin enough for me to use a knife, but you may need to use a Dremel. Next insert switch.

Step 3: Put It All Together

Next, solder two leads from the LED light to the swith. No need to worry about polarity.

Step 4: Break Some Glass

Next, you will need to break some glass. I used an old ketchup bottle. This can be messy, so rap the bottle in a towel and hit with a hammer several times. This will minimize the mess and is really fun.

Step 5: Put It All Together

Next, fill the jar with the broken glass and screw on the lid. This may be tricky, but I found if you shake the jar and glass while putting on the lid, you will be able to surround the LED equally.

Step 6: Enjoy

Finally, find a nice place to put your little light. I have mine on my night table since it's not bright enough to wake up my wife, but enough to help navigate in the night. It looks small put is surprisingly effective. The best part is there are no wires and it is very portable. Enjoy.

    Where do you guys purchase your LED's from? I've bought 'diffused' LED's from Fry's and they weren't very bright (yes I know a diffused lens is probably the cause here. I went and bought a couple of clear lens LED's from Radio Shack and connected them to a 9V battery with a 1/4W resistor, and they just don't seem very bright. Everyone's pictures of LED projects seem VERY bright, and I'm wondering if I'm just purchasing bad quality lights or maybe people are having the same experiences and the pictures just look really nice...

    i am afraid of broken glass :( how about using those glass crystals they sell in home decoration stores? they're cheap, and they come in lots of colors...makes for some interesting combinations:)

    I am going to try coloured glass next time, but you have to be careful, I tried using a green jar for my first attempt, and no light was getting through. Might have to be clear glass and coloured LEDs. Let me know how it turns out. :)

    I tried brown, (beer bottle) ultra bright green LED x2 on 9v power supply i had laying around didnt cut through the brown. :-(

    this is the first instructable i ever tried to make and it was certaintly a good choice! i had to improvise for my power source. if ur having trouble run down to radio shack. you can pick up the rocker switch their. they also have battery holders. i used one for 2 AAA batteries and mine works great. you can even pick up new LEDs at the shack. i hope ive answered some questions by  now ;P

    Great idea, if there's a busstop which glass is broken, I'm gonna take some with me for this lamp.


    9 years ago on Step 1

    seems to be a simple 9v or 12v switch that turns on off, you can find them at hardware stores

    Consider broken windshield glass from a car. You can find it on the side of the road or in junk yards. Its much safer. Great instructable!


    10 years ago on Introduction

    You can use one of the jam jar things for the bottle. You can also use this by making a led throwie, putting it in a water proof jar with glass, tie it to something that floats and have a underwater one.

    roughly how many or how strong the LED required to light this thing up?


    10 years ago on Introduction

    I'm gona do this and try with some different colored gas, bits of mirrors and see what happens. maybe some simple circuit to cycle through some different LEDs or combinations
