Each pack contains one pair of Halos, one white and one red.
Features a solid and strobe light modes.
For the absolute best visibility use the Halos above the elbow, white facing forward and red backwards. The reason for that is that you will be a lot more visible by other cars. We think that safety is NOT an option!

Two micro usb charge cables are included.
Do not bend the plastic strap, it is fragile. Use the velcro only.
