Having spent so much effort getting the battery box sorted, I decided to miss a few steps and MOT the bike so that I could use it. The battery would have to wait.
At the MOT I was told that if I had a stop light, and no other lights, it would fail. If I took the stop light off and had a reflector it would pass. Sop whilst the MOT was being done at the front, I downgraded the safety equipment at the rear. The bike passed with a Daylight MOT.
