Introduction: No Solder BMX Light Mod for Under $10

*UPDATE*

I have now added a night - shot of the spread of the LED,please take a moment to notice it :)

I have had this idea in my head for a long time, I have always wanted to add a led to my bmx bike securely.

So I started looking around and I ended up finding some "cool white" led's - they turned out to be orange but that doesn't matter, they were led's.

My brother tried the first one and it blew straight away, it was then I realized there was more to an led than I thought.

I came across a question in the forums where someone had asked what resistor they needed so I asked why do you need a resistor?

Iceng was the man who gave the answer and he asked me if I had any resistors - I didn't so he offered to send me some.

Three weeks later I got a package in the mail with the resistors! Eager to try them out I set up a small circuit and they worked so well!

Now that I had all the pieces I was ready to start the project, I found some speaker cable and tore it apart and found some old electrical tape (I didn't know how to use a soldering iron), a few tools, a 9 volt battery and I took off on an adventure!

This turned out quite well but unfortunately the camera I was using couldn't focus on the light at night so I couldn't get a photo with the full effect.

Anyways,it worked well so why stay at the intro? Lets go to step one!

Step 1: Get Your Bike!

First and foremost you need to have the right gear to do the job.

Your bike will either make or break this model so lets explain that first.

On a bike there are a few parts that we will be focusing on, they are as follows:

  1. Headset
  2. Stem
  3. Top bolt
  4. Front brake attachment

You will first need to check if your front tube has a hole in it for the front brake cable to come out.

You will next need to check the stem, this is the bit that connects the handlebars to your bike - if the bolt holding it on has a hole in it you should be good.

If not you will have nowhere safe to run the cables.

The idea is to run the cables on the inside of the tube so they are contained.

See the photos to learn exactly what I mean with the holes.

If your bike fits the rules you can test the LED!

You have to put the led through the front brake cable hole so test now to make sure it fits.

Step 2: The Electronics.

To be able to wire this up you will need the following:

  1. Cable**
  2. 9 Volt battery
  3. Led Diode
  4. Resistor, 330

Cable**

The cable size will vary according to different bikes, you will have to measure and cut your own cable.

I am on a BMX bike and I used one 3' strand of cable cut in half to make two 1.5' strands of cable.

Measure the headset and leave a little extra for connecting the battery.

Step 3: The Resistor Part.

OK, you have made it this far - Hooray!

It is time to put the resistor in our circuit.

You will start by cutting one of the of the cables in half and then stripping all 6 ends.

Take the cable.s you cut in half and put the resistor in between them, you now need to twist it together as tight as possible.

Once it is twisted up you can tape it up!

Once you have two cables again you can move on!

Step 4: The LED

Light emitting diode.

It is time to add the LED to our circuit.

Take the cable without the resistor ad make sure you stripped the ends.

You will now take one of the legs of the led and wrap it up the same way as you did with the resistors.

Don't add the other wire to the remaining leg yet otherwise you won't be able to thread it through the headset.

Now you are going to thread the LED through the top of the stem, do it whichever way you find best, the main thing is to keep it attached to the wire!

Once it is through you can move on!

Step 5: The Resistor Part Two.

Time to connect the resistor.

You are going to take the cable with the resistor in it and thread it through the same hole you used for the LED.

Now make sure it is poking out of both eds far enough and attach it to the LED.

Do this with the same wrap thing you did before.

Now you have to insulate one (or both) of the ends of the LED so they don't touch and surpass the resistor.

Once you have done that you can put the LED in the brake cable hole like shown and move on!

Step 6: Battery Time!

Now it's time to ad the battery!

Sit the battery in the stem and cable tie/zip tie it to the stem.

I used rubber bands and it fell off.

You have to test the cables to find out which way they go and once the LED lights up use a piece of electrical tape to hold them there!

If you have a 9 volt connector I suggest you use that instead, the tape was sort of 50-50 and it got in the way.

Now you can light it op and ride around with your new toy!

Thanks for reading and please give a big thanks to Iceng for making this possible.

Please share this around and please also take a second to vote for me in the last day of the Make it glow! contest.
