NiteRider: The Swift™ 500 gives you more than enough lumens at our lightest weight for headlights (82 grams). NiteRider® makes this headlight USB rechargeable for convenient on-the-go charging. The Swift™ 500 features a highly durable light housing with Dupont® Fiberglass reinforced nylon meeting all required FL1 Standards for impact testing and water / dust resistance.Vmax+™ 150 is NiteRider’s first taillight featuring COB (Chip-on-Board) LEDs, which for cyclists means it emits highly visible flash patterns in a smaller, more compact package. Its feather-like light weight makes it perfect as a wearable safety light—easily clipping onto straps, belt loops, and more.SWIFT™ 500 FRONT LIGHT FEATURESLumen Output: 5005 Modes with Run Times: 1:40 – 32:00hCharge Time: 1:45h at greater than 500mA | 3:00h at 500mAWater / Dust Resistant IP64 RatedUSB RechargeableSWIFT™  500 TYPICAL RUN TIMESLow - 10:00h at 150 LumensMed - 3:40h at 250 LumensHigh - 1:40h at 500 LumensFlash - 12:30h at 500 LumensWalk - 32:00h at 30 LumensVmax+™ 150 TAILLIGHT FEATURESLumen Output: 1506 Modes with Run Times: 5:30-27:30hCharge Time: 2:00hWater / Dust Resistant IP64 RatedUSB-C RechargeableVmax+™ 150 TYPICAL RUN TIMESFast Flash - 13:15hSlow Flash - 10:45hDisco Flash - 11:15hPulse Flash - 7:30hHigh Steady - 5:30hLow Steady - 27:30h
