What Are OEM Headlights?

Before you can know what OEM headlights are, first you have to know what OEM parts mean. OEM parts stand for Original Equipment Manufacturer, which means the parts to the vehicle are the originals that came on the vehicle from the factory. Or, in easier terms to understand, the part is a direct fitment to the vehicle.

Buying OEM headlights vs aftermarket headlights can get kind of confusing, depending on why you’re looking for new headlights, so here we’ll clear up a few commonly asked questions about OEM headlights!

How Do I Tell If My Headlights Are OEM?

The best way to find out if your headlights are Original Equipment Manufacturer (OEM) headlights is by finding the part number on one of the headlights.

Pick either side, and for almost all headlights, the part number will be on the backside of the headlight.

Unfortunately, you might have to unbolt the headlight and pull it out to see the number, because it could be located in a few different-hard to-read spots.

This should be the only number you’ll find on the headlight, which should start with a P or PA, and then is followed by a set of numbers.

If your car wasn’t originally fitted for LED headlights, you will probably have to do some converting to a LED headlight setup.

What Is an OEM Bulb?

An OEM bulb would be the exact same kind of bulb your vehicle would have left the factory with.

Other types of bulbs might fit into your OEM headlight setup, and they might not.

these bulbs might fit, but they could cause you problems.

What Does OEM Equivalent Mean?

Sometimes, a part might not be made from the factory any longer, making it hard to find OEM parts for certain vehicles, especially older vehicles.

Therefore, aftermarket companies will pick up the slack, and make parts that are OEM equivalent.

This would mean that, by most accounts, the part you get may not be OEM certified by the factory.

However, if you get it from a certified aftermarket dealer, the part you purchase will bolt right up as if it was an OEM part.

Which Is Better – OEM or Aftermarket?

Which Is Better - OEM or Aftermarket?

OEM is always better if you’re looking for a part (i.e a headlight or headlight bulb) to match up to your vehicle perfectly.

If you are looking for an upgrade on a certain part of your car, then aftermarket is the only way to go.

No OEM parts for your car would be considered an upgrade.

However, if for some reason a certain part for your car just simply isn’t being made anymore, then you might have to go OEM aftermarket equivalent to get a part that is an exact match.

Note that there are some cases where private owners will sell OEM parts.

However, chances are that this is because the company knows the manufacturer has stopped making the part, and will sell it to you with a price markup.
