Hella External Fitting Auxiliary H4 Plow Lamps differ from standard External Fitting Auxiliary H4 Lamps in that they have turn-signals and marker lamps.

Hella External Fitting Auxiliary H4 Headlamps are E-code certified. Some models include City lights. E-code lamps have a wide beam that lights the road from side to side. They are useful at 300-400 feet. There is a sharp horizontal transition from dark to light about 1" high at 25 feet. A wedge of light on the right side lights up roadside signs. On low beam you can expect about four times as much light on the road as a sealed beam and twice as much on high beam. Because of the tight beam control, these lamps can be aimed very accurately which facilitates the use of upgraded bulbs without offending oncoming traffic. These lamps are not certified for use on public highways in the US and are sold for off-road and racing purposes only.
