On the first evening of ownership I was struck how little light the original bulbs gave inside the car. I guess that’s the problem after years of being used to the brightness of led lighting in more modern cars.
Simple solution …. swop them. I had a bag full of them left over from a previous project on my MGB so it seemed an easy solution. Need to remember that the bulbs are polarity sensitive so if at go first they don’t work then turn them through 180 deg.
These are the bulbs I used – pretty cheap, bright and effective …….
