Ive heard of people building there own lights with bits of trade sites etc. Anyone done this? are they good quality and was is worth it?

also a quick q, if you run a 2 light lightset with only one light will power still be wasted on the empty cable?

thanks

yep. The extra electricity spills out into the light body. You need to tie a knot in the end of the cable.

Modified a couple of P7 DX torches and triple Cree's from Kaidomain. prior to the dedicated bike lights they now sell. Check out http://www.candlepowerforums.com/vb/forumdisplay.php?f=86 for all you need to know.

how do you 'tie a knot' in the end of the cable? i presume its a technical term?

spock it's not a technical term, you do literally have to tie a knot in the cable. Electricity from batteries can't move around tight bends as it moves a whole lot slower than normal electricity. If you tie a knot in it that will make ensure all the electricity goes to one light only and isn't wasted.

Would routing one cable uphill have the same affect?

Say if the gradient was to steep for the weak little battery electricity to climb?

🙄 😯 😕 😆

They're taking the p!ss 😉

If a second light isn't on then it won't be consuming power (or it may be using a tiny bit in the electronics but nothing compared to the power used in the actual light so don't worry about it.

I've done a couple of DIY ones using Cutter LED kits and old Cateye (metal) MR11 bulb housings which fit perfectly. There's load and loads that's been written about it but if you honestly did believe the thing about the knot, you may be better just going for something like the Dealextreme light…

Top be honest, just a bit of blue-tack in the end of the spare cable will be enough to stop the electricity leaking out. It's quite slow and viscous.

Clubber. Do you have any other info on your cateye conversion?

Have a good read on the Candlepower forum bike section.

Slight hijack – where do people get the connection cables from?

A chap on here was selling the plugs that go in the end of loose cables, to prevent wasting the 'leccy. A few quid, but pay for themselves after a few rides.

DrP

that went well 😀
