Me too, don't see why it shunt. Just needs a reflector ont back. T'other un fell off last year, it was just a stick on one.
From the gov web site: https://www.gov.uk/guidance/mot-ins...s/4-lamps-reflectors-and-electrical-equipment My Bonneville passed its last MOT without having a separate reflector, so either the rear light lens (Motone Lucas style) is itself a reflector...or I was just lucky
BALLAX!!! Just rung MOT shop to mek sure that thid got some stick on reflectors, and mi test is Saturday mornin, not tomorrow!
It is a fail but I got away with it last year on the Bonneville. Told by tester I "should get one" but passed anyway.
