I got round the 'US' issue by buying some effin' bright orange LED bulbs (took me two attempts, the first lot I bought weren't very bright at all, as witnessed at Ford Fair) to put behind the red indicator lens. They flash orange, even through the red lens, and I get to retain the reversing lights as per factory. Interestingly, my reverse lights, with the exact same bulbs, seem to light up the road a lot more with US lenses than with the Euro spec ones, they have a slightly different texture on the inside of the lens itself and it seems to do a much better job of letting light get through.
