If you want to stop your Christmas tree lights from blinking, you can try the following solutions:
1. Check the power outlet: Make sure the outlet is working properly by plugging in another device to confirm it is supplying power. If the outlet is not working, you may need to replace it or find a new outlet.
2. Check the fuse: If the fuse is blown, replace it with a new one. This will usually solve the issue.
3. Check the bulb: If the lights are blinking due to a faulty bulb, replace it with a new one.
