Question: how much power does the generator make in amps?
Document: This product was sent very promptly. I have ordered three other products from Bikeworld, and they are always prompt. This headlight/rear light/generator combination is fairly well constructed, compared to others that I have purchased. Plus, they included directions for installation. It is always a challenge trying to mount the headlight; I had to rig up my own bracket for the handlebars since I have a basket in front on my cruiser bike. One draw back is that the generator is quite noisy.
i have a bike basket and a handle bar light is sometimes hard to see. This headlight, mounted below basket, works great. EZ to install with a few simple tools.. but you do have to  install it!! This is really old style retro stuff but i love it!! Recommended for those  who need a light and have some(not much) mechanical ability. If you can do simple bike repairs...no prob.Vendor mailed  very promptly.. excellent service.
We have had others of these items, however this was returned because it was faulty.It is a good item for all bikes.
Third, the headlight is weak. Finally, be sure both lights are grounded to the bike frame.
The bicycling past was not all that great.
Over priced, but cheaper than new technology. Good for kid bikes. I would buy only if you don't mind the wires and how clunky the product is.
I used one of these for years back in the '50s only because batteries were so expensive and wore out so fast. The modern LED lights are Far more efficient and batteries last a lot longer now, too. The worst thing about it was that the light became very dim when you slowed down, and went off completely when you stopped. It also put a very noticeable drag on the bike making it harder to pedal. Only if you enjoy making fire with flint and moss would you appreciate one of these.
I ordered two of them for me and my husband. One of them, it did not even turn on the light... Other one turned on but the brightness is really weak. And hard to keep the light on. Not consistent. At least one of them could turn on so I don't say one star but I'm not sure whether you want to get this...
I have a similar system which was given to me for free for the bulb inside. I needed this bulb for another 12 V system. This was at a light-bulb specialty store and it was the only bulb of this type they could find. Where in God's name can you buy 12 V/0.5 A miniature screw-cap bulbs? ?
I bought this for my brother as a gift and I have not seen it in action yet.
Answer: yes
