"Thank you. All the lights seem to work when turned on. However the car just failed the MOT on 2 points. A damaged passenger side rear reflector ( near side) which I replaced today, and ‘rear fog lamp not working, offside rear’. We have had the car for years and the reflectors have never had bulbs in and it’s always passed the MOT. I’m very confused "
For the avoidance of doubt and misunderstanding....reflectors do not have bulbs behind them They merely reflect light that is shone on to them.
