2015 Toyota Corolla Bulb Sizes

Quick reference

LED vs halogen upgrade considerations

The 2015 Toyota Corolla is a popular car for a reason: it's reliable and easy to maintain. When it comes to lighting, you have a few options. While the higher trim levels of the 2015 Corolla came with factory-installed LED low beams, most models use traditional halogen bulbs. If you're looking to upgrade to LED bulbs, there are a few things to keep in mind.

First, you might encounter CANBUS errors. CANBUS is the system that your car uses to monitor its various components, including the lights. LED bulbs use less power than halogen bulbs, so the CANBUS system might think that a bulb is burned out. This can cause a warning light to appear on your dashboard. To avoid this, you can buy CANBUS-compatible LED bulbs or install a resistor.

Second, you might need adapters to install your new LED bulbs. This is especially true for the low beam headlights. The factory halogen bulbs are held in place with a clip that might not work with an aftermarket LED bulb. Fortunately, there are many affordable adapter kits available.

How to replace each bulb

• Low and high beam headlights: The low and high beam headlights are located in the main headlight housing. To access them, you'll need to open the hood and remove the plastic cover behind the headlight assembly. Then, you can twist the bulb socket to remove the old bulb and install the new one.
• Fog lights: The fog lights are located in the lower bumper. To replace them, you'll need to access them from underneath the car. You might need to remove a few plastic clips to get to the bulb.
• Turn signals, brake lights, and tail lights: The rear bulbs are all located in the tail light assembly. To access them, you'll need to open the trunk and remove the plastic cover. Then, you can twist the bulb sockets to remove the old bulbs and install the new ones.
• Interior bulbs: The dome and map lights are easy to replace. You can use a small flathead screwdriver to pry off the plastic covers. Then, you can simply pull out the old bulb and plug in the new one.

Common lighting issues for this generation

The 2014-2016 Corolla generation is known for being very reliable, but there are a few common lighting issues to be aware of. The most common issue is premature burnout of the halogen low beam headlights. This is often caused by a voltage issue, so it's a good idea to have your electrical system checked if you're experiencing this problem. Another common issue is moisture in the headlight housings. This can cause the bulbs to short out or the lenses to become cloudy. If you're experiencing this issue, you'll need to have the headlight housings resealed or replaced.
