The new best headlight

[anotherkiwi]

German law states that lights must operate from a dynamo, with operation from a battery being optional.

It's a ridiculous law IMO.

It has been modulated recently to take into account e-bike batteries. So independent battery powered lights no, wired from the main battery yes.

So how do I wire my Cree light onto my battery? There is a light button on the display ...

 

[soundwave]

the wire goes down to the motor but you dont get very much power and you need the dealer to turn it on as default is off.

How much is not much?

Sorry but they are just numbers and I have no idea what my double cree lamp uses?
I was once told that volts will give you jolts but amps will light your lamps...

Eh? What are looking for, smoke and magic? A genie in a bottle?

There is 8.4W (1.4A @ 6V) available to power the front light and 0.6W (0.1A @ 6V) for the rear. It wont be enough to power your cree lamp. The feed is intended for low powered lamps at rip-off prices.

In other words it's like having a big bucket of water but only a small hole to get the water out from...

Good analogy.

It honestly is worth trying to find a way to source a feed directly from main battery voltage.

the pack you have is 8.4v @3.4amps 3400ma

You'll be able to draw more than 3.4A unless your cells are rated for 1C.

EDIT: On second thoughts, those cells have a max discharge of 2C, so 1C is probably a good conservative limit to ensure a long service life. In a 2P config, they'll be happy to deliver 6.8A.

Easier to stick your tongue on and see if it tingles....

I'm not going to try and tell you why it's a bad idea to ride while heavily intoxicated, but I promise that you will eventually reach a point in your life where you look back and wonder what the f**k you were playing at.

Life is short - both yours and everybody else's. Don't make it even shorter.

I was going to say "come over on a Thursday night and I'll teach you how to be moderately intoxicated" but he is English and that will never work with Spanish red wine...

To run your cree light from a 36v battery, you need one of these. You connect it directly to the battery by splicing into the main battery wires or connections. Set its output to 8v with a meter, then connect your light to the other side. Put a switch on one of the two battery-side wires to switch it off when not being used.

I once went for a canal towpath ride after guzzling a bottle of red.. seemed a good idea at the time and I didn't fall in, but came close....

Anyone know how you fit the light to the head strap, when I fit it it just points down,
