What is a trunk light bulb?
Your car’s trunk light bulb is what illuminates the trunk when you open it. Depending on your vehicle, the bulb can be a small, standard filament bulb powered by a series of relays or a light strip that activates when you pop open the trunk. These bulbs can last for around five years, but they are susceptible to damage and will burn out over time.
Although you don’t need a working trunk light bulb to drive your vehicle, it is a helpful tool that allows you to clearly see your trunk and access your belongings when it’s dark.
When should I replace the trunk light bulb on my car?
Here are a few signs that it’s time to replace your trunk light bulb:
Lights are completely out: If your trunk light does not turn on at all when you open your trunk or press the trunk light switch, it’s time for a replacement. Your light may be burned out or faulty.
Dim light: Flickering or dim trunk lights indicate dying bulbs. Replace a dim or flickering trunk light bulb sooner than later to further avoid complications.
Damaged bulbs: If you notice cracks or corrosion on or around the bulb’s glass, you should have it replaced.
Lower visibility: If you have trouble seeing the contents of your trunk, you may need to replace your trunk light bulb.
How often should a trunk light bulb be replaced?
On average, trunk light bulbs last five years. If you use LED lights, your trunk light bulbs could last up to 12 years or more.
Pro tip: Routinely inspect your trunk light to ensure the bulb is working. If you notice any issues, take your vehicle to a mechanic for a replacement.
Can I replace my trunk light bulbs myself?
Yes, you can perform a DIY replacement for your trunk light bulbs, but it's highly recommended that you take your vehicle to a car repair shop for light replacements. Since they are highly fragile, your trunk light bulbs could burn out faster if they are mishandled or installed incorrectly.
To ensure your lights are properly installed, your best option is to get a certified mechanic on the job.
