Ok, so the bulbs are different... thanks... this reminds me, my sister and her North American husband and I were night driving in the UK recently, and they commented on how bright my TLCs headlamps were on high-beam, and were very fascinated by level control. Getting off-topic here, but in the USA, he drives a Dodge pickup with large 6cyl turbo diesel (6.5 litres ??), and couldn't believe how smooth the cruiser's diesel is. He thought it was a petrol version before i told him it is diesel.. Well, i dont think it's as smooth as some other diesels. We sampled the new Merc R class diesel last weekend and that was very turbine-like.
