Automotive Headlight Bulb Review - Auto Express
Auto Express have published the results of their annual review of several automotive headlight bulbs. 'For this year’s test, we concentrated on the single-filament H7 – the most popular halogen bulb in Europe. Performance versions have been around for some time, offering 30, 50 and 60 per cent more light 75 metres in front of the car. But the past 12 months have seen the arrival of 80 and 90 per cent versions. Do they work? We test the leading standard, plus 30, plus 50 and higher (we list them as 50 plus) and blue bulbs, as well as one designed for off-road use, to deliver our verdict.'
