Probably the easiest way to power your LED clip is with a USB re-chargeable battery.
I used this 1150 mAh one (at least it looks like this but there might be different models, mine is model PPS2) http://www.amazon.co.uk/Duracell-Mobile-...005EF2TG4, which was light enough to mount on top of my headphones with some velcro. The three LEDs only draw something like 150ma in total so it should last for even the longest gaming sessions. I bought a spare just in case it ran out but I think you could just connect the charging USB cable between the battery and your PC in emergencies to keep using it whilst it's charging. They've got an on/off switch built-in as well, so you can just switch off the battery rather than having to unplug the lead from the clip.
To connect the battery to the clip, you could wire a USB socket to your LED clip but you probably haven't got one handy and they might be expensive or difficult to buy. What I did was cut one end off a USB cable and cut up a couple of audio leads I had lying about, leaving a plug and a socket each with a tail of wire left on and wired the audio plug to the end of the USB cable and the audio socket to the clip. You can see the socket in this photo of my prototype: http://postimg.org/image/5loonogpt/
If you wanted a bigger/longer-lasting battery, you could get this, although it might be a bit heavy to mount to your headphones in which case you'd have to have it on your desk, with a lead going to your clip.
