Wattage probably varied then. I got failed on an MOT for having 'wrong
bulb' in rear lights. I hadn't - just two different brands.

They were pulling your plonker. They have no way of measuring the light
output. The usual reason for a 'fail' is the wrong colour due to the
plastic of the 'lens' having deteriorated.
