Step-by-step instructions on how to build a rear mounted bike light with turn signals for day and night use, so drivers can see you and where you are going. All comments are accepted, I would like to hear ways i could improve this.
Step 1: Materials and tools
-6 leds-color is a personal preference-Red/amber main light, yellow for turn signals
Don't use blue lights like i did, after making it i was informed blue is reserved for police
-2 mini-toggle switches
-1 Slide switch
-9v snap connecter
-1 Project box-any size bigger than 4"x 2"-aluminum cover is needed
-1 Bic pen or Mechanical Pencil
-Hot glue gun
Step 2: Optional: Prototype on Breadboard
Try Before building-use a breadboard. If you are not using a breadboard you may skip this step.
Step 3: Drill holes for aluminum plate
Mark where the holes will need to be, on top of the box, having the plate facing away from the cover. Drill or ream holes so that the plate fits flush to the box. Screw the plate in-place with the thread of the screw is on the out side of the box.
Step 4: Mark and Drill holes for Leds
Take the four leds and make them in any shape, i made mine in a square. mark and drill the holes. also cut holes where the wires will run for the turning lights. Cut the Bic pen barrel in half, theses will be mounted on the sides and used to hold the turning lights. Also cut a hole large enough for the slide switch.
