If Morgan are following this thread I'd expect a rear reversing light option to become available in approx 4 years (2020)...
Although no antipodean owners have confirmed yet, the Oz spec M3W has a reversing light as standard, seemingly replacing the rear fog light. It also has an extra high up stop light on a stalk located between headrests in front of filler. This is probably why the reversing light wiring is already in the standard loom on UK models, with gearbox switch already connected.
