Hi Rod,
Happy New Year to you. 🥳
Unless the Ministry of Transport has gone soft the fact that your bike is MOT exempt will not stop that one know it all traffic cop giving you a tug.
Reality is all the GB police services have been so under-funded for so long, the days of roadside-check operations are long-gone. If a particular patrol "tugs" anyone, the modern-bike rider with the undersize numberplate and noisy likely-not-E-marked exhaust offers far easier pickings than pulling an old Britbike on the off-chance they
might be able make out a LED bulb through the lens facets.
Have you looked at the pattern produced by an LED bulb in an H4 lens? You may as well become the Guy that believes dazzling every other driver by riding around on main beam is acceptable.
With respect, far-and-away the vast majority of LED headlamp 'bulbs' on old Britbikes are BPF fitted in old Lucas lens/reflectors; dazzle anyone with that combination ...
By "LED bulb in an H4 lens", you mean a P43t-base LED array in a modern lens/reflector intended for an incandescent? If so, those LED bulbs are so expensive, anyone using that combination deserves to be done while stupidity isn't illegal.
Joking aside, to be clear about this:-
. the tester's manual wording alone shows how much real technical input went into the change;
. the primary requirement is politicians are "seen to be doing something", after years of inaction;
. while my mate Rishi's focus is on avoiding another 1930's-style Depression, the police have two hopes of any significant funding increase, and one of them's Bob;
. some bright spark worked out the second criterion could be met by kicking the DVSA (Driver & Vehicle Standards Agency) collective arse to shift policing the problem to MoT testers;
. however, because of the first criterion, in reality, the MoT change'll make ten percent of bugger-all difference to The Problem - of drivers being dazzled by LED headlamps - because we've had years of
ECE-approved LED headlamps with piss-poor lens design (completely unaffected by the MoT change) fitted new, and we'll continue to have 'em for years to come. 😤
