I went to a motor show yesterday and enjoyed the journey more than the show. In my personal point of view, I have had enough of Yankee Tanks. Here in NZ they are just taking over all shows. Mustangs have become the most boring car in my life , just like a white Corolla.
In any case, I've done a 400km trip to the show and back and again I can't stop thinking of the lights. I've had both of the last Hyundai I30s and now I've got the Holden Cruze as company cars, and neither of them have the lights of the G. It is just a pleasure to drive with that amount of lighting, and the car obviously.
Some years ago the question came up as to why have these Cibie lights concave lenses. I was told by someone it is to keep them clean longer. They have a high pressure cushion in front of them and all the small bugs get deviated. Here are 2 pictures of the front of my car with just that proof. I think it will depend very much on the size and weight of the bug. For instance if you go through a swarm of bees, it will not help, but this is a clear indication of the theory.
Any other reasons of the lens shape?
