Car Parts: A Look at Lamps, Flashers, and Fuses

Introduction

Shopping for the right car parts can be a tremendously difficult task in this day and age. This can particularly be the case if the car parts that you are seeking involve lamps, flashers and fuses. Surprisingly, when it comes to car parts, these types of car parts are very high tech in this day and age.

Understanding Car Parts: The Fuse

The term “fuse” refers to a device that protects wires and other devices from overcurrents. It consists of a wire that is designed to melt when there is too much current present and the wire overheats. Some fuses have a band of metal instead of a wire. Because different fuses can bear different electrical loads, it’s important to have the right fuse for the right amount of protection. On a car, these are usually located on a panel specially made to contain fuses.

These fuses help prevent wires from being destroyed due to overheating. This is important to understand because it can be much more difficult to have a wire replaced than an appliance like a headlamp or even a radio. Protecting the wires also helps prevent fires.

Understanding Car Parts: Thermal Flasher

The thermal flasher is also located on the fuse panel, and is responsible for turning your flashers and turn signals on and off. When you turn your signal on, the flasher uses a switch to turn the bulbs on by allowing current to flow. Heat from the current bends a piece of spring steel so that it touches a contact and transmits the electricity to the signals or hazard flashers. As the spring steel transmits its electricity, it cools down and returns to its usual position, breaking contact with the device that sends the electricity to the bulbs. You then see your flasher turn off.

Understanding Car Parts: Headlamps

There are many different kinds of headlamps these days, and they have seen much innovation and change. Many years ago round headlights were standard on all vehicles—it was the easiest shape for headlamp manufacturers to make. However, technologies in production have enabled different materials and filaments, as well as shapes, to be used in headlamps for the last 20 or so years, and headlamps have become a design aspect of cars.

Replacing your fuses, flashers, and headlamps yourself is fairly easy, and you can find replacement parts at any auto parts store. Fuses are often sold in bundles, with several different load capacities available. Always make sure you choose the right one to protect your car.
