SHEZZA is spot on, I've got DEPO black internals and I've had them on the car since November'ish.
DEPO did make RHD lights but they have been discontinued, you can only get LHD lights now.
Unlike the UK beam cutoffs that "kick" at the sides, these are more US style and are flat with a step up which makes them easier to adjust to avoid blinding oncoming traffic.
You can get them still off eBay (where i got mine) from around £400 shipped.
Found these after a quick search, £399
