Why LED-headlamp flashing or occasionally extinguishing?

The cause may be in the charge, connection, controller or electronics in the headlamp. The indication whether the occurrence recurs in cold start, after heating or when a particular light is turned on helps narrow the search for error.

If the problem arises only on one side, record both headlamps. Attach a warning from the dashboard or a diagnostic printout if you have it. This information makes it easier to decide what to check first.
