Before I retired I would ride as long as I could before winter hit New England. Since I worked 10 hours a day that meant that I had to ride in the dark. I think it was in 2008 that I bouught these Cygolite 420 lights that were excellent for night riding. But I gave up night riding after that and quit when it got too dark to ride, going into the gym and staying in shape until spring. I put the Cygolites in a drawer and forgot about them. I retired in 2015 and could now ride in daylight. People began telling me recently that I need lights to be visible both front and back. I went to the local bike shop and got some nice rechargeabel flashing tail lights. But I had no lights for the front and noticed that the shop had a clearance rack with cygolite 420's for $75. I don't remember what I paid for my cygolites in 2008 but I remembered I had them somewhere. I went home and found them thinking they would be no good after all this time. Boy was I wrong! I took them out of the drawer I had not opened in 17 years and found the charging wire with an end that is no longer made. The other end is a standard USB cable connector. I had three of them because I used two on the bike and one on my helmet. People said I looked like car coming at night. I put one of the old lights on a charger and it immediately started blinking green indicating it was taking a charge. It took 12 hours but it charged! I found the helmet mount and took it on a 2 1/2 hour ride. It lasted the whole ride! I charged the other two and got the same results. Never throw anything away!

Best wishes,
