I don't need to. I comment from personal experience, and don't rely on the internet as my souce of information.

Unlike the fundamentalist cyclists (hi chephy!), I drive, too. The issues of glare from any road user is a significant one. I've been getting it cycling to work in the dark every morning in my winter as drivers pass without dipping their lights. It's worse in rain.

Of course, the issues become even worse on MUPs where cyclists with uber-powerful lights believe they have free reign to "light up their way". But the danger of glare from maladjusted lights (deliberate or otherwise) on bicycles is something I have experienced on more than several occasions.

I have ridden with various lighting set-ups, but have relied on the intelligent optical configuraton of European designs that require only a 3W globe to light my way and enable me to be seen by other road users without blinding them. I've used the old Cateye halogen lights, and currently use a simple 3LED light for commuting. All adequate, and I've never felt threatened or had an incident of any sort using all those set-ups.

By the way, I never referred to BAH as a moron. The description was used in a generic discussion of the merits of any cyclist with powerful lights. I appreciated, however, his humour, And I accept that he would take enough care to ensure the lights are adjusted to avoid blinding other road users. I hope that includes standing 50 metre away and looking at the lights as a car driver would?

And since when has it become fashionable to scream your posts in bold text at everyone?
