This can happen if the bulbs, are not producing 21w draw and cause fast flashing. Can also happen if wiring or connectors have an issue (inclusive of the earth wiring used by them)

You could try new bulbs in the first instance.
You will need a multimeter for anything else and/or physical checks/observation of the associated wiring
