Want to install a hernia headlamps do not know how to do their own models of lights ah! How can we see that ah?
Headlight assembly above a place should be marked, H1 - H7
Car headlamps have two watts is a 12v is a 24v, and now there are hernia headlamps and so on.
Your car will have a laser light on the model logo, you can remove the light bulb can see. Or you can see from the headlamp bulb shape can be distinguished out. If your car has only two headlights, the bulb is double filament, that is H4.
