What is a license plate light?
License plate lights are placed above your vehicle’s license plate so that it can be seen when it’s dark. Driving without properly functioning license plate lights could leave you subject to penalties like traffic tickets.
Since these lights are usually inexpensive to replace, it’s ideal to replace them as soon as possible when they stop working.
When should I replace the license plate light on my car?
Because it won’t affect your ability to drive, a bad license plate light is an easy car problem to miss—which is why it’s a good idea to check on them occasionally.
Here are the most common symptoms to look out for:
License plate light won’t turn on: If your license plate light won’t turn on at all, there could be several possible culprits, including a burned-out bulb, a faulty socket, a blown fuse, or wiring problems.
License plate light won’t turn off: If your license plate light won’t turn off, the assembly could be experiencing a variety of electrical issues. A certified mechanic can look at your license plate light assembly and determine what parts, if any, should be replaced.
License plate light works inconsistently: A license plate light that only works some of the time could be related to an electrical problem or a loose connection somewhere in the system. A mechanic should be able to help you find the culprit and determine the right fix.
Excess moisture in light cover: Water and electricity don’t mix well—so if your license plate light isn’t working and you notice water present in the cover(s), the problem could be due to excess moisture in the system.
Visible damage: If your vehicle experienced physical damage around its license plate area, it’s a good idea to check whether the license plate lights themselves were affected.
How often should a license plate light be replaced?
License plate lights only need to be replaced if you’ve noticed they’ve stopped working. After a certain amount of usage, the light bulb’s filament can eventually fail.
Some light bulbs and lamps will last longer than others. LED license plate light bulbs can generally be expected to last longer than incandescent bulbs.
It’s often reasonable to expect a license plate light to last the life of a vehicle, but it’s not uncommon for them to fail prematurely, either—especially if they’ve been exposed to moisture or other types of physical damage.
Can I replace my license plate light myself?
Replacing a license plate light on a vehicle is a pretty easy fix in most cases—and you can save a lot of money in labor costs for this repair by doing so. It usually consists of unscrewing the light cover and swapping out the burned-out bulb.
That said, while the basic steps for this repair are straightforward, some license plate light assemblies can be trickier to work with than others—especially if you end up needing to replace additional parts. If you don’t feel comfortable replacing your license plate light yourself, you can always have a certified mechanic do so for you.
