Do LED Christmas lights have fuses? Like the incandescent strings before them, the LED strings have a fuse in series with each side of the AC line, located in the plug. Usually there is a trap-door in the plug to open and access the fuses, or there may be a section that pulls out.
Likewise, Why do LED Christmas lights have 3 wires?
The string uses a full-wave rectifier (improves flicker) and splits the diodes between the plug end and receptacle end (so both plug and receptacle are not too large). So for an extra wire per bulb this design gains redundancy– one bulb of any or multiple pairs can be missing or open and the string still lights.

Can you use a regular light switch with LED lights?
A standard dimmer switch cannot be used with an LED light as you will never be able to dim the LED light either completely or not very well. LED lights need their own special electronic dimmer switch to have a fully functioning and dimming light.
