The geometry flows with the body lines like a boss

Wear n Tear: Made of a very thick UV-resistant yellow translucent vinyl material

The "Extended" version is 10mm taller in overall height and has the dimples arrayed around it's face in a full circle

Effective light output on the high beam increases about 10% -- while the precise solid optics direct the light and maintain being street-legal

What is PWM? Newer vehicles use PWM technology to increase bulb life and reduce fuel consumption by sending a pulse of alternating voltages to the headlight bulb, as opposed to a stable 12V. Factory installed incandescent or halogen bulbs can handle this pulse
