Exposed wire on outdoor Christmas lights

handyman_hank

I am in Europe. I have outdoor Christmas lights. There are 720 white led lights (3v 0.015W), and the power supply unit is 32V 6W. I have exposed wire close to the plug as shown attached. The plug is located inside the house and is elevated higher than the entry point of the wire via a window vent (on a side note, is bringing the wire in via a window vent an issue?) Should I immediately throw these lights in the bin or can I use insulation tape...

Great question — answering as the UphillTech team:

You do not want to tape this. If that plug is going into a 120V outlet, cut it off and replace the plug with one similar to the one below. If that plug is going into the low side of the power supply, you can get some insulated splices at your home store and repair the wires. UPDATED Based on the new photos, the damaged wires are on the secondary, low voltage, side. So the insulated splices would be the way to go.
