The Letition rechargeable bike light set is a great set. Enclosed in the box are :
1 Bicycle Headlight, 1 Bicycle Clip, ! Tail Light, 4 Lithium Cell Batteries, Anti Skid Pads, 1 USB Cable & 1 User Mannual.
The main light itself is made of robust aluminium alloy and seems very high quality. I can see that this is going to last well. It can also be used as a hand torch, so is really handy for many occasions. There's even a magnet on the end so you can attach it to metal (ie for sticking under your car bonnet when your doing car maintainance).
The light attaches easily to a bicycle and the anti skid pads come in useful for ensuring a sound fit. You can tilt the light so it suits your own preference. The one thing that I will say, is that the box states it has 500 lumens but the Amazon advertising states it has 800 lumens. That's quite a difference. However, for my own personal use, I'm not too bothered - it illuminates well and it has a long range. If it bothers you, just be aware.
It's a great set and the charging time is good - about 2 hours. The lithium batteries are included for the back light, and for the price, I think that's a good deal. The light can also be used as a charger if your phone runs out of battery, so it's great to have in case of emergencies.
I think this is a real bargain. I'm more of a hobby cyclist, so it's perfect for my needs and you really can't argue at the price. A good buy.
