Great daytime running headlight. I’ve already used it twice on two century rides in the two weeks I’ve had it and it was still blinking away flawlessly throughout the rides.
If you use this on your handlebars for a front-facing white light, the green battery status LED's are absolutely blinding if it's dark outside. Bright daylight is fine, but if you need to flip the light into the solid beam mode for early mornings, or rides that extend into evening, it's kinda miserable have those green lights searingly bright pointing up at your eyes the whole time.
This light weighs almost nothing and is small enough that I hardly notice its addiction to my handlebar setup. Hopefully it will make me a little more visible on the road
Bought the Trek Ion to replace a similar front light but have found the Ion to have better battery life - and it seems more durable. Very pleased with it.
The USB-C charge port is sunk too far into the device, and charging cables just pop out. Crazy design flaw.
I’ve had Trek lights now for years. I love them and they’re a great product. Just don’t wash them in your laundry. 😆 I bought this front light to make a rear red light. Bought some red translucent 1/2 inch sticker dots to make a rear light. For some reason I’m having difficulty finding a rear red Trek light. I’ll make this work so help me.
