One other electronics 101 point--LEDs are diodes. That means they only allow electricity to travel through them in one direction, and they work with DC. If the wires from the fan are AC, the fan may not work because half the cycles will get blocked. If they're DC and you put the LED in series, it will only work if the diode is oriented correctly. Try switching which pins connect to which wire.

Reply to comment by Ex-maven in Trying to replace LED’s in my Halloween inflatables. Whenever I touch the bare wires coming out of the fan (that previously connected to the dim LED’s) to the new LED, the fan shuts off. What’s going on here? *Edited to include previous research by boeckman
