2024 Subaru Crosstrek Bulb Sizes (Headlight, Tail, Fog)

Quick reference

LED vs halogen upgrade considerations

The 2024 Subaru Crosstrek comes with a mix of halogen and LED bulbs, depending on the trim level. If you have a base model with halogen bulbs, you might be tempted to upgrade to LEDs for a brighter, more modern look. However, there are a few things to keep in mind before you do.

First, you'll need to make sure you buy the right size and type of bulb. The Crosstrek uses a variety of different bulb sizes, so it's important to double-check the size of the bulb you're replacing before you buy a new one. You can usually find the bulb size printed on the base of the old bulb.

Second, you might need to install a CANBUS adapter. CANBUS is a system that monitors the electrical system in your car. If you install an LED bulb without a CANBUS adapter, the system might think that the bulb is burned out and give you a warning light on your dashboard. A CANBUS adapter will trick the system into thinking that the LED bulb is a regular halogen bulb, so you won't get any error messages.

Finally, you might need to use an adapter to get the LED bulb to fit properly. Some LED bulbs are a different shape than halogen bulbs, so you might need an adapter to get them to fit securely in the socket. You can usually find these adapters online or at your local auto parts store.

How to replace each bulb

Low and High Beam Headlights

To replace the low and high beam headlights on your Crosstrek, you'll need to open the hood and locate the back of the headlight assembly. The low beam bulb is the one on the outside, and the high beam bulb is the one on the inside. To remove the old bulb, simply twist it counterclockwise and pull it out. To install the new bulb, just do the reverse.

Fog Lights

To replace the fog lights, you'll need to get under the front of the car. The fog light assembly is located in the lower bumper, on either side of the grille. To remove the old bulb, simply twist it counterclockwise and pull it out. To install the new bulb, just do the reverse.

Front and Rear Turn Signals

To replace the front turn signals, you'll need to open the hood and locate the back of the headlight assembly. The turn signal bulb is the one on the very outside. To remove the old bulb, simply twist it counterclockwise and pull it out. To install the new bulb, just do the reverse.

To replace the rear turn signals, you'll need to open the trunk and locate the back of the taillight assembly. The turn signal bulb is the one on the very top. To remove the old bulb, simply twist it counterclockwise and pull it out. To install the new bulb, just do the reverse.

Brake and Tail Lights

To replace the brake and tail lights, you'll need to open the trunk and locate the back of the taillight assembly. The brake and tail light bulbs are the two on the bottom. To remove the old bulbs, simply twist them counterclockwise and pull them out. To install the new bulbs, just do the reverse.

Reverse Lights

To replace the reverse lights, you'll need to open the trunk and locate the back of the taillight assembly. The reverse light bulb is the one in the middle. To remove the old bulb, simply twist it counterclockwise and pull it out. To install the new bulb, just do the reverse.

License Plate Lights

To replace the license plate lights, you'll need to remove the two screws that hold the license plate bracket in place. Once the bracket is removed, you'll be able to access the license plate light bulbs. To remove the old bulbs, simply pull them out. To install the new bulbs, just push them in.

Side Marker Lights

To replace the side marker lights, you'll need to remove the two screws that hold the side marker light assembly in place. Once the assembly is removed, you'll be able to access the side marker light bulb. To remove the old bulb, simply pull it out. To install the new bulb, just push it in.

Dome/Map Lights

To replace the dome/map lights, you'll need to pry off the lens cover with a small flathead screwdriver. Once the cover is off, you'll be able to access the dome/map light bulbs. To remove the old bulbs, simply pull them out. To install the new bulbs, just push them in.

Common lighting issues for this generation

One of the most common lighting issues with the 2024 Subaru Crosstrek is that the halogen headlights can be a bit dim. If you're not happy with the brightness of your headlights, you can upgrade to a set of LED bulbs. As we mentioned earlier, you might need to use a CANBUS adapter and/or an adapter to get the LED bulbs to fit properly, but it's a relatively easy and inexpensive upgrade.

Another common issue is that the turn signal bulbs can burn out prematurely. This is especially true for the front turn signal bulbs, which are located in the headlight assembly. If you find that you're replacing your turn signal bulbs more often than you'd like, you can try upgrading to a set of LED bulbs. LED bulbs last much longer than halogen bulbs, so you won't have to worry about replacing them as often.

Finally, some people have reported that the dome/map lights can be a bit finicky. If you're having trouble with your dome/map lights, the first thing you should do is check the bulbs. If the bulbs are good, then the problem might be with the switch. You can try cleaning the switch with a can of compressed air, or you can replace it altogether.
