Led lights

Does anyone know how to put led lights in a flying panda or any yoyo for that matter.

It’s just trial and error. Most people just figure it out for the yoyo they are installing them into.

Try taking off the caps. Attach one (or two if you can) LEDs to a CR 2032 and put it inside the caps and tape or glue em in?

You should add a resistor between the LED and battery.

Not really necessary, it wouldn’t blow out the LED.
