best battery powered bicycle lights image
Jesus Hipp
I have a huge and heavy 16 LED flashlight that works well. But well, it's huge and heavy and the "D" cell batteries rattle... though they do last along time. Any suggestions? I'm not spending more than $30 ish. Need to be a quick release and usable with a handlebar bag in place also.

Try this light, it's a bit more money 34.95 but it will do what you want and the store will ship. You can get the phone number off the site. Power On Cycles, just too let you know its a Recumbent shop. Mark and Linda Powers are great to deal with.

How can I light my bicycle lamp using dynamo and rechargeable batteries ?
Mrinal
How can I light my bicycle lamp using dynamo and rechargeable batteries in such a way that the lamp lightens by the dynamo while pedaling and at the same time rechargeable batteries get charged so that it can be used to light the lamp when i am not pedaling ?
p.s. I have a bottle dynamo .
I don't need any product which does this directly. I want to do it myself. So , please suggest some way to do it.
Answer
Essentially - you can't. Especially not with a bottle dynamo.
Basically, the output of the dynamo is just sufficient to light the light. There's nothing left over that you could store in the batteries. In theory, you could load the dynamo differently and get more power out of it, but that won't work with a bottle dynamo because it'll just start to slip - you'd need a hub dynamo for that.
Otherwise, it depends very much on what type of lamp you have and what kind of copronmise you're willing to do for the standing light. If, for example, you had a LED lamp with a single LED in it, you could just parallel a supercap to the LED through a resistor. In practice, this would suffice to give you a few minutes of (much reduced) 'standing light'.
However, this kind of kludgery is (technically) from about 10 years ago. Meanwhile, light manufacturers have noticed that people would like to have decent lights on their bikes that continue working even when standing still and have come up with those:
