Step 6: Adding other LEDs
Add LEDs anywhere else you like. I have a combination of glow sticks and bare LEDs on my bike.
The axles in my wheels are a shiny, un-painted metal, so directing LEDs onto these makes them reflect the light in all directions.
I also added 2 blue LEDs under the bike to shine directly on the ground.
The red rear light is a store-bought bike light.
My spedometer also has a light so I can see how fast I'm going at night. The speedometer light is rigged on some stiff wire to allow for it to be bent into the right position.
Be creative, and light your bike however you prefer.
