im sure the purpose of sidelights are actually for parking rather than driving in dusk etc thats when you need headlights on.
how are the bulbs doing anyway?
i lost all faith in led bulbs a long time ago but these cree bulbs i keep hearing about seem to be a bulb that sound like they can handle bumps in the road without failing.
I don't quite understand why UK, and some parts of mainland Europe, insist with demanding that cars are supplied with switchable "side" lights. DRL I can understand, modern Europe with only front DRL I can't quite understand. Parking light function, yes, can be handy, but the number of people that drive with no lights or sidelights only because THEY can see where they are going - well that's a strange one. I'm sure if the police had enough time to stop them they would change their ways to avoid getting fines etc. Maybe a quick re-read of the highway code is needed, and if it is not in the current issue then it should be
Cree do seem to be way out in front as regards controlled light output and durability are concerned.
It seems that a lot of LED lighting in transport and other places - office/factory lighting, is still in the dark ages, a really good concept but horribly let down by poor implementation. Modern traffic signals (traffic lights) - rows of LEDs out, same for bus exterior lighting and sadly same for some lighting we have been trialling at work. It is not the LEDs that are fragile, it is the way they get connected together to make up the light arrays - cheap crap designed by idiots who really should know better!
