Introduction: DIY LED Police Bike Lights

In this tutorial I will show you how to make cheap and custom LED police bike lights. NOTE: I made these lights before, so the tutorial may not be very descriptive. If you have questions message me!

Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Materials

First gather your materials. You will need...

perfboard (the size depends on how many LEDs your lights will have)
LEDs (mine are red and blue high intensity LEDs)
Wire (any gauge is fine. I would recommend 20-24)
Resistors (Use a calculator to determine the amount of ohms)
Heat shrink tubing (I used a variety of sizes)
Connectors (optional)
Switches (both toggle and momentary on)
Switch housing (I used a PVC T-connector)
12v battery source (I used an eight slot AA battery pack, but I will be installing a rechargeable battery)
Switch Flasher (SHO-ME EMERGENCY LED STROBE FLASHER 11.1005SF)
Mini zip ties (for attaching the lights to your bike/vehicle)
foam (optional)
Solder

Tools:
Soldering Iron
Drill
Pliers
Lighter
Knife
Wire stripper

Step 2: Building the Lights

First lay out your LED design or pattern. I did two rectangles with a total of 12 LEDs for the handlebar lights and two rectangles with 6 LEDs for the rear lights. If you are doing two rows of LEDs per light, then make sure that your LEDs polarity is in the right direction on the perfboard.
Remember to measure the correct length of wire and give plenty of "wiggle room". Also remember to heat shrink the soldered connections between wires to ensure protection.

EXAMPLE:
+ is the positive side of the LED (long side)
- is the negative side of the LED (short side)
~| is a piece of connection metal (I use the clipped of LED legs)
-+-+-+-+-> is the positive wire (red)


#470# is the resistor (make sure you are using the correct resistor for the LED and for 12 Volts)



-+-+-+-+-+-+-+-+-> + + + + + + ~|

- - - - - - |
+ + + + + + ~|



Step 3: Wiring the Lights and Controller

After you have built the desired number of LED lights, proceed to wire them up to the battery and controller (switch flasher). If you bought the sho-me switch flasher then the instructions should be included. Just in case here is the instructions:

O---- Switch ------------> +12V
| | /
| F | ----- Red Wire -----/
| L |
| A | ----- Blue Wire ---------------> Left LED
| S | ----- Yellow Wire ------------> Right LED
| H |
| E | ----- Black Wire -----------------------------------> -12V
| R |
| | ----- White Wire ------O--- Momentary Switch ---> +12V
||

Step 4: Setting Up the Switches

After completing the connections to the battery and the controller, begin to connect the switches. The switches are marked out in the last step.

Next test your lights, and if this tutorial has been thorough enough then they should be flashing now. If they are then proceed to the next and final step. If they are not flashing check your wiring and connections.

Step 5: FINAL STEP

Now your lights should be complete. Put a thin piece of foam behind each light to protect the bikes paint and to protect the solder joints. Next zip tie the lights to the desired place (i.e. Handlebar, rear rack, frame etc). Find a safe place to put the battery and controller (I made a case out of duct tape to protect the battery and controller from puddles and dust). Now, find a good place to put the switch box where it wont get bumped or moved. Finally use zip ties to organize the wires and make sure that the wires wont get broken or caught on your legs or in the gears.

Here is a vid of the final product. If you have questions or comments feel free to message me. HOPE THIS TUTORIAL (my first) WAS COMPLETE AND DESCRIPTIVE! ENJOY YOUR LIGHTS!

    The legality of blue lights differs by jurisdiction. In Australia I'm pretty sure blue lights are allowed on, emergency vehicles, planes, human powered vehicles. So the restriction applies only to motor vehicles that aren't an emergency vehicle and not a plane.

    Blue bicycle lights are even sold at K-Mart

    how many resistors did you use. and did you put one between every led. and where is the diagram?

    I used one resistor per light bar, with the lights wired in parallel. The diagram didnt really work out the way I had planned. If you need me to send you a new one I would be happy to via pm.

    Yeah no problem! Yes that is a great kit but is not as robust as the Sho Me Flasher. Good luck!

    Great instructions. I would like to give this a try. And if anyone is interested to know where you can find a SH-ME LED Flasher, can find it here:

    Hey...i am curious..is it legal to ride with this light....i can see how no cars will ever mess with me...but I hope i dont get a ticket by the cops. Either ways...this is just too good man! I will build one for the heck of it :)). Thanks for sharing such awesomeness!!

    Ah...never mind...i read the disclaimer. I think i will change the colors of LEDs to Red and Orange or some other colors. No biggie.

    Haha yeah! I just have to legally protect my self, ya know? And I ride with em and have even pulled someone over while on my bike (go figure). However the police department knows I have it and just think im some stupid kid. They dont really care as long as I dont harass other people etc. I only use em on Halloween or when I ride at night.

    How did you wire the rear lights to the SHO-ME EMERGENCY LED STROBE FLASHER 11.1005SF?

    Wired them the same as the front to the same wires.

    1 per unit but i would recommend wiring it in parallel not series.

    ok, that oznium website is awesome, but what resistors would i need for blue LEDs and what one for red LEDs. what resistors did you use?

    Yes they are a great site. The owner has been a great help and they have wonderful customer service. On the page where you buy the LEDs, if you scroll down, there is another section where you can buy the resistors. There is also a note that tells you which resistors are for what color LED. PM me for more info or help. Enjoy!
