Review on 🚨 NP NIGHT PROVISION DUO-120 Red/White Strobe Rear Bike Light USB Rechargeable COB LED Lights PSR-120 Police Patrol Red/Blue Strobe Safety Warning Firefighter Police by Ryan Will

These little lights are worth their money so far. Plus and minus together 😁; 1. They are sealed well which makes them waterproof. Just make sure the rubber pads for the charging port are properly covered, I removed mine and used clear tape to protect it.2. Long press button for constant red/blue flashing, good for me as VFF.3. Short press the button and you can switch between all different patterns. This is very helpful if you are a firefighter like me.4. Highly visible especially in low light but still effective in daylight. Just don't think it's a $100 emergency light. But as I said, they are great and worth the money. Flexible attachment rubber, just hope it doesn't break too quickly, especially when caught in hot and cold elements 🙂. Overall I think this is the best choice for any cyclist. 👍👍👍
