Sorry thems ugly....and it does indeed look like you will need to obscure your lights... kinda defeats the object....fit them to protect the van in a shunt, but fit them so the guy cant see you braking :?
i have a set of them, not on a bus currently though.
my mate had a real early deluxe with them on too and i didnt think they looked that bad, nice to see something different sometimes... they only cover a bit of the lower part of the rear light which doesn't matter on a yank bus as there is no bulb in the bottom half anyway
