The missus' 169 came manual free. Obviously a race lightening feature. As is, presumably, the special dark dipped lights, saving on all those heavy photons. The dipped lights are shockingly useless. Light up the hedges nicely, but useless for actually seeing the road at all - they need to swivel in towards the centre more. The main beams are very good however, and I don't want to move them. Delving under the bonnet, it seems there is an adjuster on the top of the unit, a plastic slotted nut thing that looks as if it will move the whole caboodle, which I don't want to do. Is there any way of adjusting laterally the dipped/main units independently of each other, or is it a choice of seeing with dipped or main but not both?
