there was a post about a high level brake light that i can not find

the high lvl brake light had a flasher unit fitted with flashed a few times before staying on and they aske if it was mot passable
'vosa private passenger and light commercial vehicle testing book says
' reason for rejection'
a stop lamp
(a) missing, insecure, obviously incorrectly positioned or does not face to the rear
(b) inoperative, excessively damaged, deteriorated or obscured so that they are not visible from a reasonable distance
(c) shows other than a STEADY red light when the service brake is applied, or remains on when the brake is released.
so for mot point of view the high level flashing brake light would fail the mot.
