how to stop christmas lights flashing

The best way to stop Christmas lights from flashing is to check their wiring and make sure it is secure and not loose. If the wiring is secure, you can try replacing the bulb, as it may be burned out or defective. Additionally, you may want to check the circuit breaker or fuse box to make sure there is no problem with the electrical system. Finally, if all else fails, you may need to purchase new Christmas lights.
