The Dun-Bri Group, based in Buntingford, Hertfordshire, provides Ighting and electrical products to workshops, bodybuilders, garages, trades and road transport firms.
Andrew Strath, Dun-Bri Group sales director, believes there is no regulation regarding the maximum or minimum wattage for headlamps, other than that vehicles used before 1 April 1986 require a minimum of 30W.
"In theory, there is no wattage limit, but if you want to stick with approved equipment, then 70W is what all manufacturers stick to. However, on any vehicle used after 1 April 1986 the bulbs must carry an approval mark, ie a BS Kite Mark or EC marking. You will struggle to find high-wattage bulbs with an approval mark. They are available but most state quite clearly on the packaging 'not for road use'."
He continues: "You could fit these higher-wattage bulbs, but the offence you would be committing is to use a bulb without type approval.
"If an enforcement agency knew this information and removed the bulbs to check, it would probably result in a bit of advice or a vehicle defect rectification notice, unless the lamps were adjusted in such a way that they caused dazzle, which is a separate offence," he concludes.
