The Toyota Avalon is a full-size sedan that serves as Toyota’s flagship vehicle. Since its introduction to the market in 1994, the Toyota Avalon has been known for its reliability. However, some components of the Avalon will still need replacement after typical wear and tear. One of the important Toyota Avalon parts that will need to be replaced after a few years are the headlights.
When to Replace your Toyota Avalon Headlight
Your headlights perform an essential function. Without proper illumination from your headlights, you increase your risk of getting in a motoring accident due to poor visibility.
To ensure that your headlights won’t fail you when you need them the most, it’s important to look out for signs that your headlight bulbs or the headlight assembly itself needs to be replaced. Here are some reasons to replace your Toyota Avalon headlight.
If your Toyota Avalon has halogen headlights, you’ll notice that after some time, the lights will start to get dimmer. This is a common warning sign that your headlight bulbs will need to be replaced soon.
Blown Out Bulbs
The most obvious reason to replace a headlight bulb is when it finally fails. For LED or HID bulbs, they don’t usually get dimmer with age. That’s why you’ll have to wait until they blow out before replacing them.
Flickering lights can be a sign of bulbs that need replacing or of faulty wiring. It could also point to corroded terminal connections or some other system component failure.
Scratched Cover Lenses
If one of your headlight cover lenses gets too scratched up that it affects the brightness of your headlights, it’s time to get a headlight assembly replacement.
When you’re planning to replace your headlight bulb, make sure to replace them in pairs even if just one of them blows out. Replacing your headlights in pairs assures you that both of your headlights are always in excellent working condition.
Choosing Your Toyota Avalon Headlight Bulb Replacement
Because of the Avalon’s long production history, the car’s headlight bulbs vary depending on the particular year and model. In general, Toyota Avalon headlight bulbs usually belong to one of two types of light sources: halogen or HID (high intensity discharge).
If your Toyota Avalon was produced before 2005, you likely have halogen headlights. From 2005, Toyota have outfitted the Avalon with either halogen or HID lights depending on your car’s particular model and trim.
If you’re upgrading your stock headlights with LED lights, it’s important to know the exact size of your headlight bulbs. Most car parts websites allow you to input your vehicle’s make, model, and year to help you find the perfect fit.
Toyota Avalon Headlight Replacement Cost
A headlight assembly replacement for your Toyota Avalon can cost anywhere from $100 to $1,000 for a pair of headlights. OE replacement bulbs, on the other hand, cost around $10 to $30 per pair. Price is affected by the type of light source you prefer, whether the replacement kit includes bulbs or not, and the model and year of your Avalon.
Frequently Asked Questions
If one headlight bulb has burned out, is it necessary to change the other one too even if it is still in good condition?
No, it is not necessary to change both headlights at the same time. However, it is more practical to buy and change them in pairs. Both headlights are used at just about the same frequency and intensity. So if one has already died out, there is a high probability that the other one is about to reach its demise as well. It would be wise to have a spare in hand when that happens. Also, there may be an imbalance between the brightness of the two headlights. Since one is older than the other, it may appear dimmer compared to the new one.
What are the advantages and disadvantages of halogen and xenon headlight bulbs over each other?
A halogen bulb has a thin filament inside, which is capable of giving off a bright white light. Because of the halogen gas inside the bulb, the filament is expected to last longer than traditional headlight bulbs. However, road vibrations can break the filament inside a halogen bulb. This drawback makes the xenon bulbs more durable. Xenon bulbs don't have any filament that could break. Instead, they use two electrodes and form an electric arc to generate lighting similar to natural daylight. Xenon bulbs produce three times more illumination than halogen bulbs, too. That's why many Toyota Avalon owners have upgraded their headlights into xenon despite the higher cost.
What can possibly go wrong with a Toyota Avalon headlight?
Three things must be initially checked to know what is wrong with a Toyota Avalon headlight: wiring, fuse, and charging system. These components are commonly where the headlight problems root from, and the problem can be as simple as a short circuit or a disconnected ground. To know for sure, voltage from the wiring must be gauged. The headlight problem could also be caused by a bad fuse, a dead cell in the battery of the charging system, or a defective alternator. So usually headlight troubles are results of some electrical issues in a Toyota Avalon.
