This mode feature is designed to save battery power by preventing the head light from accidentally turning on while in storage. Simply press and hold power button 8-10 seconds to lock / unlock. The Swift(TM) 700 gives you more than enough lumens at our lightest weight for headlights (82 grams). NiteRider(R) makes this headlight USB rechargeable for convenient on-the-go charging. The Swift(TM) 700 features a highly durable light housing with Durable Fiberglass reinforced nylon meeting all required FL1 Standards for impact testing and water / dust resistance. Vmax+(TM) 180 features COB (Chip-on-Board) LEDs, which for cyclists means it emits highly visible flash patterns in a smaller, more compact package.

For added convenience, the Vmax+ 180 features mode memory, will power ON in the last mode used.
