Ituo Wiz 20 front light.
Owned for around 3 years, but barely used. The battery is roughly 18 months old. Singletrack gave the light a Recommended award when they reviewed it in the mag.
The light works fine, but there seems to be an issue with the indicator light that tells you it’s low battery when it still has plenty of charge. I’ve tested it and the light lasts for the expected amount of time, even when the light comes on almost immediately.
