Lights can overflow the brim of the box o’Lights [the supply bin] in the garage but it’s like talking to the walls trying to get the chill’Ren to take lights when they thinks they;s mIgHT be home after 0-DarK-30.  Night-Rider 650(bottom center) is a great light for after dark or before sunrise; easily recharges and lasts about 3 hours.  Bike-Planet’s rear red blinker (upper right) will induce epileptic fits (~$30.00). Leyzne round blinkers(center white and red lower right) are very effective and easy to attach.  Don’t go out without  light(S).
