Not sure I'd like them, I'm not too keen on the more common crystal lights where the reverse lights and indicators form on clear strip along the middle. I think the part of the light fitted to the boot is too long on the E34 for those to work well (they're based on the E46 style which has much shorter boot lights).

These ones are the same design in terms of light location as the original lights, except with the crystal effect. Could make the car more modern from the back if it looks reasonably "original".
