According to statements of my dealer, the MX5 trans is equipped with the necessary reverse gear electric contact to switch a reverse light.
Yes and have visually confirmed the switch is connected to wiring loom on my UK spec car. Am now mildly optimistic that a live reversing light connection will be available at the four wire rear light connector, since colour codes match from switch. Next stage will be to remove the rear dirt cover.
ETA: dimensions confirmed as those of existing rear fog light so reversing lamp ordered from
SVC
