“To be effective HV clothing should be of a colour that will allow the wearer to stand out against the ambient background found in the working environment. In practice the best colours for this purpose are likely to be day-glo, or fluorescent yellow. Where necessary the clothing should also incorporate retroreflective material to make the wearer visible when seen in headlights in poor lighting conditions or during darkness. This may require reflective strips at or below waist level on waistcoats or jackets, or strips on trousers.” – The HSE Personal Protective Equipment at Work Regulations 1992
