The idea for this instructable was to build a lighting system for my bicycle helmet that can charge with solar power during the day at work so I can use it for my bike ride home after dark. I used my existing bike helmet (Adult Standard Razor) and different components I recovered from dumpsters or bought on the super sale at different stores.
Solar Spotlight (bought on clearance at Walgreens for $1)
Low Voltage wire (100 yard spool from Home Depot)
red LED's (Scavenged from circuit boards of appliances thrown away/Mardi Gras throws)
2 Solar Panels and charging circuits from solar yard lights I bought at deep discount from Walgreens because they were cracked and didn't have yard stakes anymore (67 cents each!)
