Basic design flaws,
Verified Purchase(What is this?)
This review is from: Jazooli High Power Super Bright Heavy Duty 3W 1 Led Waterproof Front Bike Light - Black (Misc.)
While this front bike light is very well priced, it has flaws that mean I can't recommend it.
First, the electrical connection of the battery to the light is unreliable (it's two springs pressing against two tinned contact rings. The light bulb fitting and battery case can rotate relative to each other, meaning that this connection is very unreliable, turning off under shocks and jiggles.
Second, you can't see from the rider's position that the light is on - so if it fails while you're riding in a well-lit street, you think you are visible, but you are not.
Third, the light switch is unreliable and ill-placed: it's a good micro-switch, but sitting behind a rubber grommet that makes it hard to know if it has responded based on tactile feedback, while also being awkward to push, and making it likely that you misdirect the light when activating it.
Fourth, the fitting (you'll be taking the light off and on at least once every day remember) is well enough made, but has a flimsy base plate designed to ratchet from side to side. This is just too light weight and easily dislodged.
Instead I replaced this with a Smart Lunar 35 Lux Front with 1/2 Watt Rear Light Set - Black, (2xAA, 2xAAA batt.inc.): Much brighter, reliable and very easy to use without distraction. twice the price but you get more than what you pay for in this case.
