Steve,
I've talked to Paul at Williams about them. They have a pair fitted to a Landrover and at night the dip beam is brighter and more defined than the standard 7" units. Main beam is quoted as "awesome".
I also asked about compatibility with the bulb failure warning system on the Plus 8 and new +4: it seems they don't trigger a warning.
They look, in my view, rather good. Cheaper than a new Aero 8....but still about £650 the pair.
GULP!!!!!'
£650!
I fitted Osram Nightbreakers to my standard lights.
An improvement but not huge. £15 for a pair so worth a try.
My front fogs don't add anything to distance visibility.
I don't do a huge mileage in the dark and the present set up is ok.
Replacing the front fogs with spots would be an option though.
Mind you...Hela spots are not cheap...excellent light though.
