OK, had time to assess the benefits.
Answer - much better general vision on the roads. Don't know how they managed to aim the beams higher, but they have, and they don't seem (
) to dazzle other drivers, so maybe the factory settings on the 166 are just too low
£270 for the service - platinum plugs and pollen filter included, so quite good value, even if they hadn't managed to sort the lights as well
