Agree with some of the postings further up re dimly lit objects fading into invisibility.
In this battle for light supremacy...my dad could beat your dad up...things are getting out of hand, its all very well giving each new model even more ludicrous (and rather camp but each to their own) fairy lights to make them noticed, but in all this light display the poor old pedestrian and cyclist gradually become invisible, let alone all inanimate objects unless lit with fairy lights or covered in reflective coatings get increasingly hard to see too.
The other effect of this rush to fit LED's on everything is the flicker effect.
I'm mainly thinking of some of the fantastically overbright brake lights now fitted to many cars, over the top or what, so bright in some cases that nothing else can be seen when that massive glare hits you...unfortunately due to the flicker and blinding effect the following driver has no idea of the rate of deceleration of the car in front, sensibility required in this field.
It doesn't help when all the lights are crammed in together in one light unit, often chrome lined inside clear glass to give that Lexus light effect, once the sun hits all that chrome inside clear plastic then its a dickens of a job to see any lights at all...this applies especially to indicators all but invisible beside overbright headlights and brake lights.
As for the specsavers jibe, its those who can't see vehicles unless they're lit up like a council house at Christmas that need the optician most.
