This inspection applies to all stop lamps fitted.
Vehicles first used before 1 January 1936 are not required to be
fitted with a stop lamp.
Stop lamps are not a legal requirement if the vehicle is fitted
with neither front nor rear position lamps etc. (see 1.1),
Vehicles first used before 1 January 1971 must be fitted with one
stop lamp either on or to the offside of the vehicle centre line.
If such a vehicle has two lamps fitted, it should be treated as
a vehicle first used on or after 1 January 1971.
Vehicles first used on or after 1 January 1971 must be fitted with
at least two obligatory stop lamps.
Additional stop lamps
Any additional stop lamps fitted and connected must be tested. Where
extra lamps are fitted and there is doubt as to whether they are
connected, the benefit of this doubt should be given to the presenter
High level stop lamps
These are lamps usually fitted in the rear window or boot spoiler
of a vehicle and may consist of a number of light sources .
The lamp is one unit, so as long as at least one of the light sources
illuminates when the brake pedal is pressed the lamp is deemed to
be working.
Dual function lamps
On vehicles first used before 1 September 1965, it is acceptable
for a direction indicator lamp to be incorporated with a stop lamp.
