Don’t worry, when asking yourself what headlights do I need or what size are my headlight bulbs, switching to LED headlights is not as hard as it seems when you follow these simple directions.
The first thing you need to find out to change headlight bulbs on a car is what size headlight bulb you need for your car. Getting the wrong kind of headlight size automatically means that the lights will not work.
There are many different models. Each one matching a specific car model, type and even year so don’t just pick out a set of at random.
Read through our quick guide on which LED headlight bulb sizes you need, so you will know what it all means.
What Headlight Bulb Do I Need?
Looking up the answer to, what headlight bulb do I need for my car, should only take a few minutes. There are three simple ways to find out which kind of you need, these are:
1. By Checking Your Car Manual
Do you still have your car manual lying around somewhere? Good, because this is one of the quickest ways to find the correct light number for your car.
Check the contents page for where you can find the information on the replacement and what headlight size you need. Usually, the headlight bulb guide, this is either in the vehicle care section or the lighting and electronics sections.
Find the table that shows an overview of all the different light replacement numbers. The light bulbs might also be called the high/low beam headlamp.
Simply read off the number and search online for LED bulbs with the same fitting. No calculations or conversions needed.
Do you not have the physical car manual? Most car manuals are available online, now.
Do a quick online search for your car model’s manual. In most cases, you will be able to find it on the website of the car manufacturer or the dealership.
2. Finding the Number on the Old Bulbs
The more DIY handyman option is to find the replacement number on the actual bulbs. This option takes a bit more effort but you can be 100% sure that the type and size are correct.
The fitting is usually engraved into the base. Keep the above reference number overview with you so you can recognize the number sequences.
The good news is that there is no difference in fitting models between different types of LED headlights. Halogen headlights and most LED headlights bulbs are labeled following the same reference numbers.
This means that you can easily switch out your halogen headlights for LED headlights. Most manufacturers have simple conversion kits that are as easy as a plug-and-go.
3. Using an Online Headlight Bulb Number Database
Nowadays, you can reference an online directory for the correct bulb number. There are several free online directories, some more complete than others.
We recommend using the Philips Automotive Bulb Finder to answer the all-important question of ‘what kind of headlight bulb do I need’, simply type in your car model, make and manufacturing year and the directory will present you with all the numbers you need to know for your vehicle.
You are likely to be recommended a Phillips brand bulb through this search engine. However, that isn’t a bad thing as Philips Vision bulbs are considered some of the best on the market.
The Philips LED bulbs have more focused lighting compared to other brand lighting technologies. The bulbs are also moisture-proof, shockproof and can handle sudden voltage changes.
Either way, as you can see, finding what headlight bulb size and their correct replacement number is easy. It really is a matter of reading off the number from either the online or physical manual, via a fitting directory or from the bulbs themselves.
