Bicycle Valve Light, 1 Red Led, Automatic Flashing, For A/V, W/Batteries (Ag10X3), One Pair
Cost: $11.89 includes shipping.
It’s a pretty simple install, place it on your tire valves and let the motion sensor lights do their work. Basically this thing will only work if there is movement.
I have it mounted on the Torker Cargo T.
On the first night I used them, they were super bright. I was on the road for about 45 minutes. I felt great about the visibility they provided. After the second night of use, another 45 minutes on the road, the lights already started to dim. My rear LED was so dim that it was barely visible.
I was surprised on how fast the batteries drained. The LEDs use watch like batteries and the last time I checked these things can add up if you have to keep buying them. So I figured, if the batteries drained in 2 days, with a total of 90 minutes, that means I’d be replacing batteries on a weekly basis. To me this LED light isn’t worth it…You’re better off saving your money and getting a rear blinky from Planet Bike…
