To the uninitiated, shopping for car parts can be a confusing process and car lights, in particular, can be an issue. When it comes to car lamps and lighting, terminology that is unfamiliar to most is often used. But with a little deciphering, we hope to make it all a bit clearer.

Auto Levelling/Load adjustment: Internal motors that control the aim/alignment of your headlights
