17 Strategies – alternative DRLs

SUMMARY – it’s long been recognised that a dipped headlight is not the most effective day-riding light… making the bike stand out has become a more difficult problem now cars also have day running lights… an effective DRL has to work under multiple conditions… DRLs are most effective at dawn and dusk but less effective in daytime conditions of bright sun… single headlights offer poor help to drivers in judging speed and distance… but DRLs also have to provide a ‘visual signature’ so drivers realise they are seeing a motorcycle and drivers are quick to recognise single headlights as belonging to a bike… twin lights may be mistaken for a car… the ‘triangle of lights’ is ineffective in terms of daytime conspicuity but help drivers judge speed and distance more accurately… unusual lights risk not being recognised as being fitted to a PTW… like hi-vis clothing DRLs are not ‘fit and forget’…
