Legislation and requirements: Vehicle manufacturers must fit DRL to new types of passenger car and light goods vehicle (car derived vans) type approved to European vehicle requirements from February 2011 1. In practice this means that any new model launched after this date, and many launched before, will be fitted with DRL. However, existing models on sale before this date without DRL fitted can continue to be sold and used indefinitely.
Similar requirements will apply to large vehicles (such as HGVs) and buses from 7 August 2012. Motorcycles do not currently require DRL to be fitted, but most manufacturers voluntarily opt for an AHO (Automatic Headlight On) system to be installed as an alternative. Changes to European legislation will, in future permit manufacturers to fit DRL on their motorcycles
Glad you have seen the light Mike
But I thought you were very used to being kept in the dark
I recently fitted an LED headlight bulb only has 7W drain but very bright compared to 35W OE bulb, very much to be seen not necessarily to see with as I do not ride in the dark. Have to agree when leading it's much easier to know other are still behind if they ride with lights on.
