Headlights, like any lighting device, can fail due to a broken filament. The front of any vehicle is the most unfortunate location for lighting fixtures due to the possibility of collision damage, high temperature fluctuations and vibration. All these factors shorten the life of the headlights; on the other hand, the front of the car is a place in need of good lighting, so the car owner has the displeasure of changing the headlights several times during the life of the car.
There are 2 main types of headlights: sealed and replaceable bulbs. The sealed type is the most common and includes almost all round and rectangular headlights found on cars after 1980. The sealed lamp is so called because it includes the lamp (filament), reflector and lens in the form of one non-separable part. Headlights of this type come in different sizes and shapes. All Honda vehicles featured in this book, with the exception of 1990-91 ACCORD vehicles, use this type of headlight. The latest ACCORD vehicles use replaceable bulbs in installed housings.
The replaceable incandescent lamp is a product of more advanced technology. When a small halogen lamp fails, only it is replaced, while the lens and reflector are part of the car body. These headlights are used on European lighting systems. Although replacement lamps are more expensive than sealed ones, they produce brighter, better quality light.
