Miconi Bike Light Set,2400 Lumens USB Rechargeable Bicycle Lights,6 Modes 4000mAh Waterproof LED Headlight Mountain Bike Light,Safety & Easy Mount Cycling Front Light & Rear Light Fits All Bicycles

First things first, the front light in this set is bright. Very bright. It has three brightness settings and a flashing mode which flashes at full brightness.It is so bright that you probably shouldn't use the brightest mode during the night when there is other traffic on the road as it is likely to dazzle on-coming drivers. However, to light your way on dark roads and paths it will be excellent as you can see in my photos. For a bicycle light to be used as a safety daytime light it must be very bright and this front light, especially with its flashing mode, is more than adequate even on sunny days.Battery life: On a full charge, on full brightness, the front light lasts about 1.5 hours before automatically switching to a lower brightness for about half an hour. On the lowest brightness setting, which is still more than adequate for making yourself visible to other road users at when it is dark, it lasted around 7 hours which is very good.The rear light is not bright enough, in my opinion, to be used as a daylight safety light but is perfectly good for visibility at night. One small oversight is that the rear light is not angled at all. Since most bikes saddle stems are angled it makes the light point downwards slightly.One of the bonuses of this light set is how the front light acts as a power bank. As you can see from the photo the front light is charged from its USB-C port from any standard USB charger or USB port on a computer etc. using the included USB-to-USB-C cable. It also has its own regular 'power-out' USB port which you can use to charge other devices just like a power-bank. In fact, that's the way you can charge the rear light at the same time as charging the main light. Note, this light set does not come with a charger.In summary, the front light in this set is outstanding but the rear light could do with being brighter and would be better coupled with a separate, brighter, rear light for daylight use.Positives:Very, very, brightExcellent daylight visibilityPower bank facilitySimple but secure mounting bracket (front light)Negatives:Short battery life in full brightness modeFlashing mode is a fast strobe flashing effect which could have safety concerns for some people

Easy to fit, charge lasts a long time, sturdy on the bike once fitted, it doesn't flop down like some I have had.

Front light extremely bright but has different bright settings. Can be used as a hand torch too. Rear light is small and not as bright as the front, but on brightest setting is acceptable. Front light charge lasts about 2 hours on high setting before needs charging. But lasts longer if dimmed, back light lasts for hours before needs charging. Two different types of usb leads to charge them, supplied. Proven good waterproofing. Set favoures front light rather than rear. But overall not bad.

Bought 3 of these lights are bright. However one 1 of them the the hinge pin on the bracket rusted and the the plastic around it broke rendering it useless.

Fantastic for 10 months, and then the main light stopped recharging. I was very careful with this, and never left it outside or mishandled it. Its not built to last, one star.
