This is a way to let people see you at a distance while riding your bike at night. Simple to make, instal and use.
Step 1: Things You Will Need
Altoids box, 12 volt switch, multi tool, 2 9 volt battery conector tops and a sodering iron and of course 12 volt leds for an automobile (water resistant)
Step 2: Quick Soldering
Seperate and measure the led that you want on your bike. Solder the 2 9 volt connectors in serial. That way you have more pwer to the leds (much brighter) . Solder this to the switch of your choice, I prefer the flip style. You can feel its position while riding and simply move it to on.
Step 3: Position for Best View.
Position the leds on the bike and tie the extra wire down with zip ties. The Leds that I used had an adhesive backing so they were super easy to attach to the bike. Some people like the lights on the side because they are using a front headlight and a red tail light.
Step 4: Turn on and Be Safe.
Check with local laws. In some states they are strict with amber lights in front and red for rear faceing. I picked green because they are viewd easy on the eye and can be seen at least 100 feet back.
