I drive a 2013 Honda Jazz and when I drive in the dark I regularly notice other motorists flashing their lights. I've checked my headlights and they work, but it's possible that they are not as bright as other cars. To make them brighter I'd have to put them on full beam. I don't know if buying new bulbs is the answer, the handbook shows that the headlights are 12 volts, 60/55 watts. Any advice would be appreciated.
