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, here it is worth pointing that the procedure for fog lights, indicator lights, and brake lights is the same. There are three simple ways to find out which kind you should have, 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, but should you not be able to lay your hands on it, then you could check out this site for your vehicle manufacturer, the model of car and manual, hey presto you now have one.

Check in the contents page for where you can find the information on the headlight fitting you require. Usually, the bulb guide, this could either be in the vehicle care section or the lighting and electronics sections.

Check The Cars Manual

Find the table that shows an overview of all the different light fitting numbers. The light bulbs might also be called the high/low beam headlamp.

Simply read off the number and search online for LEDs with the same fitting. No calculations or conversions required.

Don’t forget a quick look online or 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 DIY handyman option is to find this on the actual bulb. This option takes a bit more effort but you can be 100% sure that you have the correct one.

The fitting is usually engraved into the base. Keep this overview for reference handy so you can recognize the sequences, Here it is an H7 bulb.

The good news is that there is no difference between different types of LED headlights and Halogen fittings, Most LED headlights bulbs are labeled following the same references.

Therefore you can easily upgrade your cars bulbs to LED headlights. Most vehicle 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 reference No., and 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 information 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 bulb fitting and their correct fitting reference is easy. It really is a matter of reading off the number from either the online or physical handbook, via a fitting directory or from the bulbs themselves.
