How To Wire LED Fog Lights

LED fog lights are a great way to improve your visibility while on the road, and they can also add a stylish look to your vehicle. RECON has a wide variety of LED fog lights to choose from, so finding the right ones for your vehicle should be easy. But before you can install your new LED fog lights, you'll need to wire them up.

Wiring LED fog lights is not difficult, but there are a few things to keep in mind. First, make sure that your LED fog lights are compatible with your vehicle's electrical system. Most LED fog lights will work with either a 12-volt or 24-volt system, but some may require a specific voltage.

Consult your RECON Fog Light instructions or the manufacturer's website to be sure. If you aren't positive, feel free to contact us and discuss your vehicle and your needs with a member of our team. We will make sure that you have a clear understanding of what you will need to complete the job, and most importantly, will know that the components you are buying will be compatible with your vehicle.

Next, you'll need to connect the positive and negative wires from your LED fog lights to the corresponding wires in your vehicle. The positive wire will usually be red, and the negative wire will usually be black. If you are unsure which wires to connect, consult a wiring diagram for your specific vehicle. Once the wires are connected, you'll need to mount your LED fog lights in a suitable location.

Most LED fog lights come with brackets that allow you to mount them to your vehicle's bumper. If your vehicle doesn't have pre-drilled holes for mounting fog lights, you may need to drill some yourself. Be sure to consult a professional if you are not comfortable drilling into your vehicle's body.

How to Wire LED Fog Lights

The following instructional is a general overview that doesn't account for unique schematics or arrangements that some vehicles may have. It is always best to consult with your vehicle's owner manual to be absolutely certain you are ordering the correct pieces, and your vehicle will accept this upgrade.

Here are the basics of how to wire LED fog lights:

  1. Start by disconnecting the battery from your vehicle. This will ensure that you don't accidentally short circuit any of the wiring.
  2. Next, consult your RECON Fog Light instructions or the manufacturer's website to be sure that your LED fog lights are compatible with your vehicle's electrical system.
  3. Once you have confirmed compatibility, you will need to install a switch on your dashboard and run the corresponding wires from the switch through your firewall and into your headlight relay.
  4. Run the fog light wires into the relay from the bumper.
  5. Once your wires are connected to the relay, you will then need to connect the lights to the wires in order to tie the fog lamps into your headlight relay.
  6. Mount your LED fog lights in a suitable location. Most LED fog lights come with brackets that allow you to mount them into pre-existing holes in the bumper. If your vehicle doesn't have pre-drilled holes for mounting fog lights, you may need to drill some yourself. Be sure to consult a professional if you are unsure of how to do this.
  7. Reconnect the battery to your vehicle and test out your new fog lights!

Aftermarket LED Fog Lights

Not all vehicles come equipped with fog lights, or you may even have existing fog lights that you would like to upgrade to LEDs. Whatever your reasoning and your vehicle's current lighting arrangement, LED fog lights are an excellent option.

Fog lights are designed to help you see in inclement weather, whether that be rain, snow, or even dense fog. They are mounted lower on your vehicle than your regular headlights, and they often have a wider beam pattern. This allows them to illuminate the road in front of you without causing too much glare, which can make it difficult to see.

LED fog lights are a great upgrade over traditional halogen fog lights. LEDs are much more energy-efficient, and they produce a brighter, whiter light than halogens. This makes them better for seeing in all kinds of weather conditions. Additionally, LEDs have a much longer lifespan than halogen bulbs, so you won't have to worry about replacing them as often.

Wiring LED fog lights is a pretty simple process as you have already seen in the instructional above, but there are a few things you need to keep in mind. First, you'll need to make sure that your LED fog lights are compatible with your vehicle's electrical system. Most LEDs will work with any system, but it's always best to check to be sure. Since LED bulbs have a substantially lower draw on power, it is unlikely that your vehicle will not be able to accommodate these bulbs.

Even if your vehicle does not have OEM fog lamps, there is likely a place on your dashboard with a removable cover that is meant to accommodate the switch for aftermarket fog lamps. Once you have found this spot, you will need to remove the cover and run the wiring for your LED fog lights through the firewall in your vehicle into your engine bay. This step isn't very complicated, but it is tedious and requires you to snake wiring through some tight places. Come equipped with patience!

Your best bet is to consult with your owner's manual to see what they say about aftermarket fog lights.

Can I wire my aftermarket led fog lights into my factory fog light wiring?

It is likely that you will be able to, however, it is best to check your specific vehicle's instructions or the manufacturer's website to be sure that your LED fog lights are compatible with your vehicle's electrical system.


If your vehicle has fog lights and you are interested in replacing them with LED fog lights, the hope is that you will simply be able to remove the existing bulbs by unscrewing them from the bracket holding them to the inside of the bumper, disconnecting the bulbs from the wiring harness, and replacing them with your new bulbs. You will need to make sure that your new bulbs fit the housing in your bumper or will need to plan on making some adjustments to accommodate the new bulbs.

Are LED lights any better than traditional halogen bulbs?

LEDs are much more energy-efficient, and they produce a brighter, whiter light than halogens. This makes them better for seeing in all kinds of weather conditions. Additionally, LEDs have a much longer lifespan than halogen bulbs, so you won't have to worry about replacing them as often.

One thing to keep in mind is that not all LEDs are created equal. There are different types and qualities of LEDs on the market, so it is important to do your research to find the best option for you. When you order parts through RECON, you can count on our exceptional customer service and quality control — our team is obsessive about providing our customers with top-quality products for reliable and long-lasting results.

What is the difference between a fog light and a regular headlight?

Fog lights are designed to provide better visibility in poor weather conditions, when there is fog, rain, or snow. They are usually mounted lower on the vehicle, and point downwards at a more acute angle than regular headlights. This allows them to light up the road more effectively in adverse conditions.

How do I know if my vehicle has fog lights?

The best way to know if your vehicle has fog lights is to either check your front bumper or consult your owner's manual. If your vehicle did not come equipped with fog lights, there may be a spot on your dashboard that has a removable cover — this is typically where the switch for aftermarket fog lights would go. You will need to run wiring from the switch to a relay, which will then break out to each separate lighting fixture.
