H4 bulb

The H4 car lamp for many applications

H4 car bulbs have been tried and tested since the 1970s. This headlight bulb can provide both high and low beam in a single bulb. However, the low beam can be slightly dimmer when the high beam is used. Therefore, many drivers are switching to H7 bulbs with a single filament. The power of an H4 is legally prescribed at 60 watts for the low beam and 55 watts for the high beam. 100-watt H4 bulbs are prohibited! A maximum luminous flux of 1000 lumens with a tolerance of 100 lumens is permitted by law. We carry H4 bulbs for cars and one H4 bulb for motorcycles in our shop.
