What is an inline fuse for?
What Does an In-Line Fuse Do? Like other types of fuses, the main purpose of an in-line fuse to protect the circuit of a piece of electrical or electronic equipment. In-line fuses are often used to protect the alternator and are designed to break the circuit if it becomes overloaded.
What’s the correct fusing for a headlight?
In a 12 V circuit, that’s less than 6 amps nominally. If you put in a 10 amp fuse, you should be ok. I have looked at some amperage vs wire diameter charts and 20 amps seems a bit too close to the 24 amp maximum for my comfort levels.
What happens when you turn on the headlights?
When you turn on your headlights, that switch activates a relay. That relay, in turn, actually provides the electrical connection between your headlight bulbs and the battery. Fuses are also involved in order to provide a sacrificial failure point to protect the rest of the wiring.
What kind of wiring does a halogen headlight use?
The factory wiring uses 18ga wires over a very long path and through an under-rated switch to power the headlights. When someone “upgrades” the headlights to halogens, the increased load overheats the switch causing its internal breaker to trip.
What should I do if my headlight light is not working?
The best way to do this is to turn the headlight switch on, connect the negative lead on your meter to a known good ground, and touch the positive lead to each headlight connector terminal. One of the terminals should show battery voltage, and the other two should show nothing if the problem is burned out bulbs.

Why do you need an inline fuse holder?
Protect your electrical installations and enhance the safety of your work with the best inline fuse holders. When safety and reliability are important, the items on our list make sure your electrical connections are always secure.
Where do you find the fuse rating on a light?
You’ll usually find the fuse rating on the side of your fuse, which will be given in amps. Fuse rating is the amount of current needed for the fuse to blow or break. When this happens, it stops the electrical power from flowing through the electrical circuit.
Can a fuse holder be installed on a truck?
With color-coded design, these inline fuse holders are easy to install on cars, boats, motorbikes, or trucks. With color-coded design, these inline fuse holders are easy to install on cars, boats, motorbikes, or trucks.
