You may have found yourself in a situation where fog has impaired your sight while you’re driving and made things difficult and still unsighted you even after you turned on your headlamp. You may have been forced to ask, can you add fog lights to a car?
If you want to install fog lights on any car, the answer is yes. When installing a fog light kit on any automobile, the most crucial thing you’ll need is the proper wiring. It is easy to come by the wiring for any make and model because it’s accessible online or in auto shops.
In most circumstances, as long as you have the proper wiring, installation should be rather simple and straightforward. You are most probably wondering how easy it is to add fog lights to a car. Let’s delve deeper and learn how you can go about this.
How To Wire Fog Lights

- Install switch, relay, and fuse holder. Take the red wire and insert one end into the fuse holder terminal with a blue butt connector. Insert the other end into the positive terminal with a male spade connector. Connect power wires from relay to battery, ground to frame, and trigger wire to headlight on/off switch.
- Insert white wire (ground) into the switch panel terminal with a blue butt connector. Then connect it to the negative battery terminal with a female spade connector. This will complete the ground circuit.
- Connect the black wire (trigger) to the switch panel terminal with a blue butt connector. Then insert the other end of the black wire into the trigger connection on the relay using another blue butt connector.
- Mount the fog light assembly, aiming each bulb downward at about mid-bumper height—the lower you install them. The more directly they’ll illuminate the road surface ahead of your vehicle.
- The next step is to know the type of wiring required for the installation. Always check your vehicle’s owner manual first to ensure that you do not void the warranty on your vehicle. In some situations, this may require you to use original equipment manufacturer (OEM) parts instead of aftermarket.
- In addition to the wiring and fog lights themselves, a relay switch is required. Typically, these switches can be purchased separately from the lighting kit itself or in a package deal with the wiring harnesses and other components needed for installation. These relays are necessary so that both beams can be used without burning out the bulb prematurely in either system.
- The final step before installing fog lights involves checking local state laws on lighting regulations for vehicles using auxiliary lighting systems like fog lights and making sure that any installed kits meet them”.
Types Of Wiring
There are two types of wiring that you can choose from; basic and HIDs xenon headlights. These two types of wiring kits are going to be different because they feature different parts that enhance your lighting system further than just the fog lights themselves. Installing either kit should be fairly straightforward if you know how to read instructions and follow them carefully.
Basic Wiring Harness
A basic wiring harness will suffice if you want to add simple LED lights. This fog light plugs directly into your fog light assembly and includes a simple switch. It’s worth noting that there are factory-fitted variants of this arrangement available, so you may have it done while the vehicle is being built.
HIDs Xenon Headlight Wiring Harness
This is for people who wish to turn up the volume on their fog lights a notch or two. The HIDs xenon headlight wire harness connects halogen and HID headlights with fog lights. This is the most difficult type of setup to install. If you are a novice, we recommend entrusting the job to a professional to avoid any unnecessary risk of injury.
If your vehicle did not come with fog lights or they are not working properly, you may be looking for a way to install new ones. After you have purchased your fog lights and before you wire them into place, you will need to have a wiring kit.
These kits are easy to use and allow you to properly attach your new lights. You can get these kits from many different places, including from the manufacturer of the lights themselves.

Can Fog Cause Accidents?
Fog causes many accidents every year. Fog has the ability to distort your perception, limit contrast and reduce visibility, all these combine to cause accidents on the road.

In essence, it reduces the capability to see other vehicles and things on the road, necessitating extreme caution when driving. Fog is created when very few moisture droplets are suspended in the air.
Light scatters as it strikes these droplets, leading to a lack of contrast and a thick white background. The fog becomes thicker as these particles become smaller, resulting in even more shrouded streets. As a result, drivers are unable to see far ahead, increasing the risk of car accidents. This is why upgrading your fog lights is very important if they are not up to scratch.
Conclusion
Adding fog lights to your car is a good idea if the lights are not sufficient. Fog lights will help you avoid accidents caused by impaired sights. Driving in fog might seem impossible, but fog lights will be of great help even in the blur. Regardless, if you find yourself in fog, whether with fog lights or not, drive carefully.
You can get fog lights at online stores or auto shops. For instance, you can get it here.
