You can get those small clip-on battery powered LED lights from computer shops, they are usually for clipping on books or tables.

I've also seen similar types of clip-on lights at Daiso too, maybe can check at their outlets.

If hard to find, you can make your own. Just get a 'A' size battery holder (big torchlight battery), a single white LED and a 68Ω 1W resistor and connect them together, there you have a cheap LED light for a Betta tank. You may have to try different Ω reistors to get the right brightness and not to blow out the LED. But this light is only for night use as it is not very bright in the day.
