The Ford Focus is a small vehicle that has been popular since it was introduced in 1998 by Ford Motor Company. It has a long line of models and body types, but one thing in common among most models is the headlight bulb.

The headlight bulb is a light that is on the front of the vehicle to help drivers see more clearly. It is a halogen light, which is the most common type of bulb. This type of light is bright and long-lasting. It looks like a traditional light bulb–only larger.

Inside the headlight bulb, there is a halogen gas that emits visible white light when electricity passes through it.

The Ford Focus has included this bulb in many of their models. It is part of the vehicle design and cannot be changed; you can only replace it if it burns out or stops working.

The life span of the headlight bulb on your Ford Focus depends on how often you drive and whether or not you use your headlights while driving at night. If you drive very little, then your headlight bulbs will last longer than someone who drives every day during morning hours.

Halogen bulbs are made to provide years of service without needing to be replaced.

Sometimes, aftermarket headlights may not perform or fit as they should. This happens if their original design and equipment specifications do not correspond to those of the original equipment manufacturer (OEM).

Designers and engineers from car manufacturing companies work to ensure that all parts follow certain specifications that dictate how parts should function, fit, and appear. As such, OEMs must adhere to the requirements and produce parts with consistent quality.

Aftermarket manufacturers do not receive such instructions. They usually copy how OEM parts look like. Slight differences may arise in their appearance and fitment. In addition, in a race to cut production costs, headlights produced may not be as functional or durable.

The same case may apply for interior light bulbs. Appearance may not be such an important factor here. However, when it comes to performance, use of inferior material to cut costs may lead to weak bulbs that don’t illuminate as they should. In addition, they may not last that long since they don’t adhere to operational requirements.

Aftermarket manufacturers often operate without the specific design instructions and standards that guide Original Equipment Manufacturers (OEM). As a result, they typically replicate the appearance of OEM parts, but this process can lead to slight variations in how these parts look and fit in your vehicle.

This issue is particularly prevalent in the production of headlights, where the pursuit of reduced production costs can result in products that are less functional or durable compared to their OEM counterparts.

Buyers will notice the difference only when they encounter a problem.

A Ford Focus headlight bulb replacement guide is the perfect tool to use if you need to install LED headlights, interior LED and SMD bulbs, or replace your existing headlight bulbs with Xenon or HID headlights. It contains all the information you need about the required bulb sizes.

Light bulb replacement guides usually contain catalogued information covering the requirements and procedures to follow when you need to change a broken headlight bulb, replace existing light bulbs, or install new HID headlights and LED light bulbs.

They save time and ensure that you do not waste countless hours figuring out what to do.

The information, however, is only available for reference purposes. Always keep in touch with your owner’s manual or local car dealership to ensure that all your bulb sizes, wattages, and voltages are correct.

Aftermarket Light Bulbs: Upgrade Options

The Ford Focus is a compact car that offers excellent agility and accuracy. It’s currently in its third generation and leaves plenty of room for some custom headlight and LED upgrades. The Focus stands out with its 160-horsepower, 2.0-liter, 4-cylinder engine that gives an impeccable 26/36mpg fuel efficiency.

On the outside, it combines its handsome and streamlined look with a functional interior. Whether you’re traveling upcountry or grabbing some groceries, a new LED lighting system will have you enjoying every moment of it. This is especially if your headlamps suddenly burn out. Get yourself the best and most durable Ford Focus light bulbs provided by manufacturers such as Putco, PIAA, and Lumen. These ensure that you never have to drive in the dark or suffer under tough weather.

A faulty light bulb can affect the safety of your car while driving. To avoid this, it is a good idea to always have a spare set of lights on you. Replacing a burnt out light bulb in your Ford Focus is not a difficult task. You just need a few common tools and a new bulb to change it yourself.

Tools needed:

  • 10mm socket with extension and ratchet
  • small flat head screwdriver (may be Phillips)
  • T20 star bit (may be T15)
  • E7 Torx bit (E6 may work as well. Won’t require buying new bits if not necessary)

When you use aftermarket light bulbs in your Ford Focus, the results will vary depending on the bulb manufacturer. Some upgrade options for your Focus are less expensive than others. You might find that you need to buy new hardware when swapping out stock light bulbs because different manufacturers use their own types of hardware in their lights.

Installation & Diagrams

  • Engage the handbrake and turn the ignition off.
  • Allow your engine to cool down.
  • Open the hood and head over to the light you wish to fix.
  • Lift the surrounding plastic trim and use the Philips and Torx screwdrivers to remove the bolts securing the headlight housing in place.
  • Pull the assembly out and remove the electric connector from the back.
  • Turn the bulb counter-clockwise to remove it.
  • Install the new bulb and secure it in place. Don’t touch the glass as prints can affect its durability.
  • Re-install the electrical connector.
  • Repeat this process for the dip beam and indicator.
  • Put the lighting assembly back in and make sure it aligns with the bodywork.
  • Screw all the bolts back in place and close the hood.

    • The easiest way is to consult the manual. But if this is not an option, check out our chart. You should find the year of manufacture of your model to check out the factory bulbs.

  1. How do I install D3S on a 2018 Ford Focus SE? I open the headlight to look inside but I really don’t know what I’m lookin at. I don’t think I see a connector for a D3S HID bulb
