ZEEFO Bike Lights Super Bright Rechargeable Waterproof LED Bicycle Lights Set With 400 Lumens Intelligent Sensor Bicycle Headlight and 4 Mode Red Tail Cycle light, Compatible with Mountain, Road ,Kids & City Bicycles, Increase Safety & Visibility

The headlight has an interesting design in that it illuminates the road ahead brightly, but has a beam 'cut off' at horizon level. It behaves like dipped beam car headlights rather than blinding other road users. So, maybe not good if you want to illuminate overhead branches on rough MTB trails, but for roads and other 'normal' environments (even those without street lighting) these are perfect - very bright against the tarmac and vehicle reflectors, but without dazzling other road users. I have seen these under another brand name which claims German STVZO compliance.I like the side illumination you get from these, although the yellow leds are lost in the mega-glow of the white led.The horizontal rotation feature of the bracket is a little loose for my liking, and is quite easy to knock out of alignment with a slight touch.The rear light is a nice bonus, but the USB cover looks a bit fragile on that one. I like the fact it remembers which mode it was in when switched off. Again, the rotation feature seems a bit loose.Overall, these are a really good set of lights for the money, and it's good to know other road users aren't being dazzled. Brackets leave a bit to be desired, but can't complain too much considering the price.

Front light it's very bright, and has different modes to choose from including a light sensor which seems to work fine. Although I am not sure about the orange side light...USB port cover it's plastic and a bit fiddly to insert the connection of the usb cable.Back light, it's bright and has different modes including a 50% less light to save batteries. Now, the problem is the cover of the USB port.It is made of rubber (good) but it's held in by a thin strip of rubber, which came loose on first opening to plug the cable in. Managed to refit it inside the hole after about 30 mins!Unfortunately, this seems to be a known design issue, and it is also mentioned on the instructions..If the cover is lost or damaged the USB port will be open to the water...

The lights seem bright enough, although I notice the front light has quite a restricted vertical beam. The front light is supposed to be 400 lumen, I have different set of lights which are 100 lumen and this light doesn't appear to be any brighter. The instructions also came in German which, well let's just say, were useless to me, although you don't need to be a brain surgeon to operate or charge the lights. The seller emailed me to say they were sending English instructions but I have still not received them. The back light is really bright.

Bought 2 in autumn for the dark winter months. Loved it. Both front and back lights are the brightest I’ve seen. Even compared with other bikers, I think these lights are one of the brightest on the road, especially after a good charge. It also has a bit of light from the sides so you can also be seen from the sides. About 2 hours on brightest setting before requiring a charge. Endured rain, snow and abuse from kids and still going strong. I like the quick release holder too. So I can easily detach it and reattach when I park the bike. And the design and materials are strong and not flimsy and brittle like others I’ve bought before. I’ve now bought 2 more for everyone in my family. Both arrived next day (prime) and in working condition.

Good: Great light capacity and options of light settings. Easiy to set up. USB charging. Good price.Bad: no info on how long it last before you need to charge it again. The back light is connected to the bike with a rubber material. Wonder how long it last before it breaks.Overall I’m quite satisfied with the product.

Today 29-Dec-2017 I cycled from home to work in London for 38.6 km (23.9 miles) in seriously heavy rain. It was first time I tested these lights in heavy rainy weather.The front bike light is not water proof. it failed just after 20 mins due to rain water entering its body. All this time the plug covering USB port was closed (I cannot say properly because this cover was always loose right from start) and did not come open at any time. The front light stopped flashing and shortly went completely off and could not be turned on until several hours later it dried fully in office and started working again.The rear light is actually waterproof. It withstood heavy rain. Its USB port however became loose just after about 2 month of use. I tried few different micro-USB cables and confirmed it was the port on the rear light that got worn out so quickly.Thus I cannot recommend these light. Very unreliable. It would let you down on a road in the middle of the trip. For this reason, no matter how it is cheap, it is not worth the money.

Delivered as promised and the Item is as described, a little early to give a full review but so far so good.

Great product! The lights are super bright. The cable ports are secure enough to withstand the weather. The front light is very to strap on to the handlebars and does not budge, unless forced. The front light then clips on in an easy single 90 degree twist. The back light uses a rubber strap to secure itself onto the bike. I place it under my seat and it stays in place no matter how many bumps I encounter on the streets. Both lights have a number of settings that can be cycled through by simply clicking the on button. Both of them can be turned off by holding the on/off button.
