Review: V bright light,great value - This bike light,is great value for money, yet very well made ,sturdy,easy to use, and has a very bright light,4 modes,and fully rechargeable,easy clip fit,and waterproof,I would highly recommend this,to anyone.
Review: Very good lights - Easy to fit and adjust the handle bar mounting. Easy to fit and remove the light from the mounting. Not sure if this review is for the 400 or 500 lumen. 400 is plenty good enough for general commuting. We have a few and they’re used quite a lot. Bright enough for night time unlit tracks (we do not do fast downhill MTB type stuff!). Use flashing all the time during the day if on roads. At night use hyper flash on lit roads. At night use steady on for unlit roads. Battery may not last quite as long as advertised but pretty good. We take a spare with us for any lengthy nighttime trips just in case. Easy and quick to charge.

## Features

- Safety first, the AMPP400 comes with maximum side visibility, securely held in place with our adjustable FlexTight bracket.
- Rechargeable headlight (400 lumen)

## Questions & Answers

**Q: Does it fit bike with aero bars**
A: The improved Flex-Tight bracket supplied with the lamp will fit both MTB and drop handlebars and is very sturdy and unlikely to move. There is a range of other mounting options, including the Cateye GoPro mounting adapter that allows you to attach your lamp upside down under your bike computer.

**Q: Why does this item only, says, warning this toy does not provide protection**
A: well if u try to keep it in your hand on full power for like 10 minuts , then it does not provide any protection :)

**Q: Any experience with heavy rains...so far my ipx4 lights died in long or heavy rain? so my next plan is to buy a diving light.**
A: I never got any mayor issue with any cateye lights even one with battery and non water resist , so as long as now for british weather i didnt have any problem with this one , solid protection from any leak except if u turn it upside down then the usb slot may be a problem :)

**Q: Please can anyone help ,i need a socket plug to "plug in' the usb cable to, can anyone advise which i need,am so confused between usb 2.4 fast charge**
A: Any will do for charging,  it's  how long it will take to charge .

### ⭐⭐⭐⭐⭐ Cateye ampp 400
*by D***N on 10 October 2025*

This cateye bike light is amazing so strong & super bright especially considering we are now approaching autumn so shorter days, it has four settings a real bright beam a more subtle bram, fast flashing beam & a more slow flashing beam This product is reasonably priced for what it can do it's so easy to mount it's been through some pretty bad rain so it is most definitely waterproof & durable
