Your factory Toyota Celica headlights can be of two types. You've got low beams, for one; they light the way well enough down most roads and through most weather. You probably also have high beams, too; these shine wider, letting you see better when it's dark and there aren't any other cars around. Whatever original Toyota Celica headlights you have, they also function as hazard lights or "flashers." These let approaching drivers know of problems or dangerous situations nearby as well as that you may need help. Some Toyota Celica trims even come with genuine headlights with built-in fog lights. These are a much better way to illuminate your way in the worst of weather, and while minimizing glare. What OEM headlights you need can vary, but from Toyota, they can be either halogen, high-intensity discharge or HID (also known as Xenon), or LED. When to change any car light bulb depends on what type it is. Replace HID headlights about every three years, or when they start to dim. Change LED headlights if their electronics fail or they go out. Replace halogen headlights, at minimum, every 2 years. The best headlights for that DIY job are genuine Toyota, made for your Celica from the get-go. Save money and order them online today, right here at our auto parts counter.
