and often extra blue strobes built into the grill on the front of the car and possibily installed behind the rear windshield too.
We have those in England now too, along with the "wig-wag" headlights on some cars. I don't think they've installed any alternating back-up lights yet, as on some U.S. cruisers. I suspect that may be because of the U.K. lighting regulations about not showing a white light to the rear except when reversing.

The same rules also say no red lights visible from the front -- If you look at some of the British cars on ThinkGood's link above, you'll see that where they have added lights besides the blue the extra strobes are red to the rear and white to the front.

It really would be a good idea if they could reduce the number and/or intensity of these lights at night. I wonder how many accidents these things have actually caused due to drivers being momentarily blinded by them.
