    highway code

    110
    Only flash your headlights to let other know you are there. Do not flash your headlights to convey any other message or intimidate other road users.

    111
    Never assume that flashing headlights is a signal inviting you to proceed. Use your own judgement and proceed carefully.

    I don't see how you or anyone else can argue this point.
