Introduction: Poor Man's Bike Light

In this instructable i will show you how to make a bike light. or a flashlight for under 5 dollars.

Step 1: Step 1: What You Need

You will need: (shown)
Tin can
Small light and holder ( 99 cents for packs five of each )
Large flat screwdriver
Electrical tape
Also: ( not shown)
Wire shears
Soldering iron and solder
Wire cutters/ strippers
Wire
Switch
Cable ties
9 Volt battery clip ( 99 cents )
9 Volt battery ( 99 cents )
A hammer

Step 2: Step 2: Cut

Now take the screwdriver and the hammer, and make a hole in the back of the can. Then use the metal shears to make it a reasonable size. Also use them to make a hole in the side of the can, and 2 holes on either side at the back for cable ties.

Step 3: Step 3: Solder Part

Now solder wires to the switch, and place it in the hole in the side of the can. Solder one wire to the light, and the other to the 9 volt battery clip. Then solder the last wire from the 9 volt battery clip to the light

Step 4: Step 4: Glue

Now glue the switch into place. Put a layer of glue aroung the hole for the light, and let it dry. Now squeeze in the light, but DON'T glue it in, you may need to replace it.

Step 5: Step 5: Finish

Now use the cable ties to tie up the wires, hook up the battery and tie that in pla e too. Also cover any exposed wires with tape. Sorry for not having a picture.

Step 6: Mount

Now use cable ties through the holes in the back and secure it to your bike.

Is there a reason why you chose a filament bulb rather than an LED? I made a bike light from a 3-LED cluster sold in a Wal-Mart to replace the bulb in a Maglite. It came with a built-in reflector and works reasonably well. It also helps that I ride the same route frequently in the daytime and know it quite well.

2 reasons: 1: it was readily available, i threw the project together in 10 minutes. 2: Not many hobos ( hopfully not offending anyone here ) can afford LED products, the filament bulbs are 99cents each.

Not to be critical, but you can afford a computer and internet access, so I find a flaw in the logic of reason number 2.

It's not pretty, but it is quite a good build. Have you thought about putting a transparent cover over the front, as I'm thinking that this would collect rain rather easily? L

True, i have thought of several modifivations, such as a cover on the front, and a waterproof battery container. You could also mod it with LEDs so it lasts longer, but remember, its called the Poor Man's Bike Light. It'ss not meant to be super complex. ( which is another way of saying i didn't have enough parts around the house :p )
