Finding The Right Headlight Bulb Fitting For Your Car

Finding The Right Headlight Bulb Fitting For Your Car

Each car has different lights and therefore requires different bulbs. There's headlightsfog lightsbrake lightsindicator lightssidelights and interior lights - just to name a few! Along with all of the different bulbs, there are also different fittings, depending on your vehicle make and model. A fitting refers to the shape and size of the base of the bulb in order for it to correctly fit your vehicle.

There are a few different ways that you can find out what fitting your car needs for the particular type of bulb you want to purchase, including using the PowerBulbs bulb finder, and checking your vehicle handbook.


Using our online bulb finder

To find out which fitting you need for your vehicle and the bulb you are buying, take a look at our easy-to-use online bulb finder.

As a quick example, if I were looking to purchase bulbs for a Ford Fiesta 2009 model, I would simply go to the PowerBulbs homepage and follow these steps:

  • Go to the online bulb finder
  • Select 'Ford' as the make, and 'Ford Fiesta 2008-2012' as the model
  • You'll then be taken to a page similar to this that indicates the fittings you need for each type of light
  • Double check this information in the vehicle handbook. This will have the most up-to-date information for your vehicle
  • Once you've figured out the fitting, you can then browse by fitting by clicking on the button next to which light you're wanting to replace (check out the image below)
  • TOP TIP - if you're unsure what you're looking for, most people want to replace the bulbs they use for normal night time driving. These have a few names: dipped beam, low beam and headlight beam are the most common.

Other methods to find your fitting

You can also contact your vehicle manufacturer for the fitting information, or simply take a look in your vehicle handbook, which should state all the fittings that your vehicle needs for each type of light.

If you are a bit more hands-on and are able to remove your headlights yourself, you can remove the headlight and take a look at the bulb. The bulb will state the fitting around the casing i.e 'H7'. Take a look at this example:


What if you can't find the fitting details for your car?

Unfortunately, we don’t always have data for every vehicle, especially as new models are introduced quite often. If your vehicle isn’t in our database then you could use one of the methods described above instead - either contact your vehicle manufacturer, look in your handbook, or take your existing bulb out to inspect it.

In summary - once you know what fitting you need, all you have to do is search for it in the website search bar and you will see all the bulbs we supply in that fitting. Pick your bulbs, place your order and you’re all set!
