One of my (many) character flaws is jumping to conclusions.
After some careful testing on the bench of my conventional twin filament tail/stop light bulb and Paul's LED one with an accurate ammeter, I have realised that when I wired the bike a couple of years ago I have swapped the power leading the two filaments. Thus, when I have been depressing the brake, the tail light filament has lit up !
This explains why I couldn't spot a difference when I applied the brake with the lights on when the LED in place - the much brighter bit was already lit up. Also explains why a Warrant of Fitness (similar to an MOT) tester complained that my brake light was crap !
Sigh.
Here endeth my confession.
Cheers,
Bevan
