If there’s a competition of the mightiest vehicles out there, the Tundra will certainly be in the finals. The Japanese full-size pickup truck is known for its reliability, great off-road performance, towing and hauling abilities, and powerful V8 engines.

That’s why it is of the utmost importance that the headlights of your Tundra are in the best possible condition. For some drivers, an update to the existing headlights might be required. Sure, the Tundra has really powerful headlights in its own, but there is always room for improvement. This is especially true for a vehicle that will spend a lot of its life in the wilderness, where the nights are only illuminated by the moon and the stars.

So, if you are one of these drivers, this article is for you. We will show you how to upgrade your Tundra’s headlights to HID lights , so that can drive safe and confident during the night.

If you prefer the halogen lights over the LED or HID types, then be sure to check out our other articles on upgrading Toyota truck headlights .

The first thing you need to know about fitting xenon bulbs into your Tundra is that they require a ballast for direct connection with the electrical system of the vehicle. The ballast takes care of converting power coming from the battery into appropriate current for fueling up the bulb. On top of that, it also sends power through an igniter wire for keeping the bulb lit, even during turns or hard braking.

Simply said, ballasts are one of the essential elements to HID lights . Without them, your headlights will not turn on. Of course, if you don’t have any experience with car electrical systems, it is best that you consult with a professional aftermarket parts manufacturer about which type of ballast can be plugged into your Tundra. You should also ask them about compatibility issues and what bulbs can be used safely without worrying too much about the possible damage to the vehicle’s electrical system.

Of course, Xenon gas-filled bulbs (the ones needed for upgrading Toyota truck headlights) require special care when handling them as well Their glass envelope is filled with some nasty chemical, so exposing it to oxygen and weather will destroy their quality and the light output. That’s why they should be fitted into your Tundra as soon as possible after you buy them.

If you decide that HID lights are the ones for upgrading Toyota truck headlights on your Tundra, then we can show you what kind of bulbs to choose in order to get the most out of them. You can find both types of Xenon gas-filled capsules in two varieties:

* Low/High beam;

* Single beam (driving lights);

The standard Low/High beam bulbs require external anti-flicker modules in case your car is equipped with an electronic flasher unit or when driving an older vehicle without such a device. It is done because the ballast sends power through the igniter wire at high frequency, which can cause flickering when connected to older cars. If you have a modern car with an electronic flasher unit, then you won’t need that anti-flicker module.

The second type of Xenon gas-filled capsules are single beam bulbs (they come in several varieties as well). They don’t require any anti-flicker modules to work properly and they can be used if your Tundra already has separate fog lights or driving lights.

In this guide, we will tell you about how you can improve the headlights on your Toyota Tundra, and how to keep them in the best shape in the years to come.

How to find the right headlight bulbs for Toyota Tundra?

Replacing the headlight bulbs on your Tundra may be easy, but finding the right one is anything but this. The thing is, every generation of Tundra comes with different bulb type in the headlights. The best way to know which headlight bulbs your Tundra has is to check in the owner’s manual or ask at the nearest Toyota dealer. For example, the latest Toyota Tundra has H4 bulbs, while the previous generation has 9003 bulbs, that are used both for the low beam and the high beam. While this is generally true for every Tundra out there, it is still recommended that you check before you buy.

Now, let’s assume you already know which type of bulb your Tundra has. According to the owner’s manual, if your truck is equipped with HID lights, then an H4 or H11 bulb should work just fine. However, for halogen headlights only H4 (low-beam) and 9003 (high-beam) are allowed. That means that any other types of headlight bulbs won’t fit into the lighting system properly or at all. Now that you know what will fit let’s see what options are available on the market today.

The first thing you might want to do before buying a new headlight bulb is to check out how much time does one of your current bulbs last and how bright it is. The whole point of changing a headlight bulb is to improve the illumination of road and the field of vision, so if you’re not getting any improvement it isn’t worth your time or money. Another thing you should keep in mind is where the light goes. If one of your headlights has problems illuminating to one side, then changing just a single headlight bulb won’t do much good, as you’ll still have bad lighting on that side. So when buying new headlight bulbs go for matched pairs, so they illuminate to both sides equally well.

How to upgrade the headlights on the Tundra?

The most obvious thing to do when replacing the headlight bulbs in your Toyota Tundra is to install high-quality halogen bulbs from reputable manufacturers. We know, there are a lot of cheap options that promise that they can illuminate the road better and that last for longer, but in our opinion, they are not worth it.

An even better option is HID headlight bulbs. These use the same technology as Xenon bulbs and generally illuminate the road much better. They also last longer than halogen bulbs and require less energy. However, they are much more expensive, especially because they can only be installed with the help of a conversion kit. This raises the price even higher. All in all, we think that they’re worth it if you want better lighting in youth Tundra.

In the last few years, LED bulbs have become a viable option. They promise even brighter light with less energy consumption and are definitely the way to go into the future. However, this is only if the housing is already made for LED bulbs like for example LED matrix headlights that are built into new premium vehicles. If you install LED bulbs into your existing Tundra headlight housing, the performance leaves a lot to be desired. Sure, the bulb will shine brighter, but the ray of light will not reach as far as with halogen or HID bulbs.

With all that said, the best upgrade option is entirely new aftermarket headlights. There are a lot of different models for the Tundra available, most of them of the Xenon (HID) variety. This means that they will illuminate the road much better and that they will last longer. Other than that, aftermarket headlights look much better than the OEM ones and come with striking LED daytime running lights. Some of the models are even customizable, with different colors for the LED lights available. All in all, if you’re serious about the lighting on your Tundra, aftermarket headlights are the way to go.
