What is the Function of Car Fog Lamps?

Before finding out how to install a fog lamp relay, you must first know the function of car fog lamps. Here are various functions you should know, among others:

1. Illuminate Dark Roads

When you have to navigate through dark roads with minimal lighting, illumination from fog lamps is needed. However, what must be considered is that the driver must ensure there are no other vehicles around. 

If the road is crowded with vehicles, the driver can use LED headlamps so as not to dazzle and endanger other drivers. 

2. Assist Visibility During Heavy Rain

When it is pouring rain, and you have already used fog lamps, the driver does not need to worry. Fog lamps are indeed designed to maximize the visibility of the driver. 

The light from the fog lamps can help the driver feel more comfortable and even safe when driving through heavy rain.

3. Help Drivers Navigate Through Fog

Traveling in mountainous areas can certainly be challenging. Especially when seeing winding roads and foggy conditions. 

When you have to navigate through such roads, fog lamps will be very helpful because the light emitted is very strong and wider. With this light beam, the driver's field of vision will be improved.

How to Install Fog Lamp Relay

Before installing fog lamps, there are rules and installation requirements that must be known first. For example, the installation of fog lamps is limited to a maximum of 2 units, and they must be installed at the front. 

Additionally, fog lamps must have white or yellow light, with the highest illumination point not exceeding that of the main lights. To install fog lamps, here are the steps you can follow:

1. Buy Fog Lamps First

Before starting the installation, you must first purchase the fog lamps. You can buy fog lamps with a complete set like cables, switches, and relays. Choose a product that matches your vehicle. 

This is because, generally, fog lamps are standard features, especially for the highest variants.

2. Start the Installation Process

To start the installation process, you can open the bumper clips located in the front wheel arch. Generally, inside there is a mount used for the fog lights. 

The fog light mount is usually located in the bumper, precisely at the bottom of the main lights. Once you find it, remove the cover clip from the mount and install the light.

Tighten it with screws, and once the installation is done perfectly, close all parts that were opened. 

3. Perform Cable Installation

The next step is to install the cables. The cables and lamp sockets should be accessible in the car's engine compartment, so additional cables need to be connected to the fog lamps. 

In addition to those cables, there is also a switch cable used to turn the lights on and off. You can route the cable from the lamp to the dashboard located under the steering wheel. 

When performing the installation, make sure the arrangement is neat to avoid any issues. 

Overall, the way to install additional fog lamp relays for cars is indeed very easy.

However, if you encounter problems during installation, you can visit an official workshop or Daihatsu dealer. Here, various car problems can be resolved well. If you don't have much time, you can book a service appointment in advance.
