Selecting the right wire for automobile Installations and maintenance of electrical systems is a major factor in keeping the vehicle’s electrical systems operating as designed. There are many types of headlight wires, and understanding which types are best suited for your vehicle can be confusing. This is why we will focus on finding the right and ideal wire gauge typically used for headlight installations and operations.
This article will guide you on how to choose the right gauge wire, run the right wire for the load and not to run too small a wire.
What is a gauge wire?
A gauge is a measurement of the diameter of the wire. This determines the amount of current that can safely pass through the wire, the gauge of the wire also tells the weight and electrical resistance the wire can handle. The wire is labeled with a gauge number, followed by “AWG.” this abbreviation stands for “American Wire Gauge.” The most common wire gauge sizes seen in automobile applications are 8, 10, 12, 14, 16 and 18 gauge. as the wire gauge increases in number and size, the diameter of the wire decreases, these two are inversely related. In other words, a 12 gauge wire is thicker and tolerates more resistance than an 18 gauge wire.
Conversely, a wire gauge of 4 can handle a current of 70 amps, whereas a wire gauge of 5 will handle a current of 5 amps. So as the gauge number increases, the amount of current that it can handle decreases.
Does the headlight use a gauge of wire?
All automotive applications and electrical systems use a wire gauge, and headlights are not excluded. In order for the headlights to be connected to the electric system and produce the resultant effect which is lightning, there must be a connection with a wire of suitable gauge.
Every headlight has a particular gauge of wire it can handle. Finding the right gauge for your headlight wire will help prevent your headlight and vehicle from unnecessary pops and damage.
Choosing an appropriate gauge of wire for your installation
It is imperative to know the right gauge of wire your headlight uses. Choosing an appropriate wire will keep your headlights functional and most likely build confidence when hitting the highway. This could be relatively cheap compared to the great loss awaiting you if you use the wrong gauge of wire for your headlights.
Most people will likely suggest using a solid core 18-gauge wire for your LED headlight. The cost difference between this wire size and a much smaller one is obviously negligible. If you would like your wires to fit into most holders or terminals, an 18-gauge wire is good.
To find the ideal wire gauge, we need to know the current-voltage drop, and the amount of voltage lost over that length of wire. a voltage drop may happen in a wire because the wire has resistance. So there’s a voltage drop when there’s resistance that is consuming voltage as the voltage is traveling through the wire. This means that, the longer the wire is, the greater resistance of that wire, and the more voltage drop.
You can ask a mechanic for a headlight for further information on installation.
The keys to selecting the best gauge of wire for headlight installations
Here are basically simple tips for selecting the right gauge of wire for headlight installations:
- Understand the purpose of the gauge of wire for the headlight
- Identify the amperage (Amp) rating of the headlights
- Consult your manual for the recommended gauge of wire for the headlight model
- Select a gauge of wire that meets the amperage rating and installation requirements of your headlight.
- Lastly, ensure the gauge of the wire is certified to meet safety and performance standards
Conclusion
Headlights need a certain amount of amperage for proper function, in other words, the voltage has to supply enough amperage to the headlight. As the amperage flows from the battery down to the wire and then to the headlights, it needs to have a large enough wire gauge to supply adequate amperage to the headlight without resistance in the wire affecting it, so that the light can function properly.
Finding the right gauge of wire for your headlight installations is a way to avoid future crises.
