Great looks and safer lighting make these DOT approved lamps a logical upgrade. The 55/60 watt H4 bulb with the diamond cut or wave cut reflector delivers powerful illumination. The ice style has a smooth, clear lens and is also available in a skull style version. The trillient style has a tri-bar with a blue dot and the blackdot tri-bar model features a wave cut reflector. (except in 4 1/2 model)
