Two deal extreme lights – one battery

As the title really – if I were to get two dealextreme bike lights (http://www.dealextreme.com/details.dx/sku.25149) could I run them off one battery. Pretty much like the Lumicycle setup. Would I get the same brightness but half the run time?

Yes and yes.

Well, double the 'brightness' (of one lamp) but half the the run time to be clear.

So all I need is to make some sort of Y cable and jobs a good 'un.

You might run into issues with draw- the wiring harness might not be too happy with the extra current, and likewise the battery pack itself might have a limit of what it can deliver. Not saying you will of course but it might be worth considering.

So how will I know? Anything I can do to check that all these things will be ok or is it just a case of trying it?

There's someone selling the cable for that on ebay. Not exactly cheap though.
