Agreed, best to read the contruction and use regs regarding lights. There are some big changes in the period covering Series Land Rovers. If yours is after the cut off date for inner headlights you can still have both sets but not only the inner ones. You can fit the grill lamps as fogs/spots and leave the headlights in the wings. Be wary of blocking out too much grill, I had my reg plate on the grill, looked good, but the engine overheated, its now on the bumper.
The wings are different too, would you change those?
