CAR HORN ON a BICYKLE

In this DIY tutorial i will show you how to mount a CAR HORN ON A BIKE with a few components. This project is for the person who want to make it just for the fun of it or the one who want to be safe out in the traffic.

I came up with the built for about five years ago at the age of 12, now a couple years later i decided to make a project out of it.

Step 1: The Video, END RESULT

Step 2: Components Needed

• CARHORN, CARHORN
• BATTERY, (OLD LAPTOP BATTERY, NOT A BOMB)
• MOMENTARY PUSH BUTTON, MOMENTARY PUSH BUTTON
• GAUGE ANGLE, GAUGE ANGLE
• ALLROUND FIXING BAND (GALVANISED BAND), ALLROUND FIXING BAND
• NUT
• WIRE, WIRE

Step 3: PREPARE CAR HORN

• Screw on the Gauge Angle on the back of the horn using the nut.

Step 4: MOUNTING THE MAIN COMPONENTS

The horn and battery will be installed using the pre existing cage bolts.

1. Mounting The Battery:

Put the battery along the bike frame, "roll" the all around fixing band around the battery and bike frame. Match up the ends of the all around fixing band and put the cage bolt thru the holes, then screw the cage bolt into the frame of the bike.

2. Mounting The Car Horn:

Start by taking out the cage bolt from the bike frame, follow up by putting the gauge angle on the mounting point and tighten the cage bolt thru the gauge angle.

3. Mounting The Momentary Button:

The button is placed between the handlebar and the shifter. (When the wiring has been done it will keep the button in place from beneath.)

Step 5: WIRING

1. Negative wire from battery to car horn.
2. Positive wire from battery to button, from button to car horn.

Step 6: PUT IT TO USE

This is how I decided to use the horn. Here

I see you have not used a relay or a transistor, I think it will help to preserve your laptop battery even longer?

You really shoud be letting the cars go by, you have no right to stop a large car than for you to stop, but the horn was really cool

Good Stuff! I once saw a kid put a Fiamm air horn on his bike......that really got everyone's attention.

Next upgrade : the horn from a big truck, they cannot ignore that one :)

This is what I need to do. So many people reverse out of parks into the bike lane without looking.

Also, I love the re-use of the laptop battery! Had you thought about putting that in an old section of inner-tube to protect it from rain/dust/salt?

Absolutely, awesome to have some authority out in the traffic.

Great point, since the horn is temporary i didn't bother doing it. I think people would be tempted to poke the button when the bike is parked, I sure would have been.

Believe a permanent solution for the horn would be to make it portable, and of course use some inner-tube to protect the battery ;)

Because why not lol! How about two horns, for that satisfyingly loud harmonious sound!

Yes! I need one of these for my bike. Thank you for the idea.
