It could be the punchline to an old joke, and yet this picture taken on a dual carriageway shows that it takes seven council road workers just to change one light bulb. The photograph shows six men in high-visibility jackets standing around with their arms crossed as one colleague scales a ladder to check a traffic light. The photo was taken at the junction of the A30 and the M5 in Somerset, near the new town of Cranbrook, Devon and featured men working for a firm carrying out contract work for Devon County Council.
