Toyota 4Runner Bulb Size

Toyota 4Runner Bulb Size Chart

Replacing your Toyota 4Runner ’s parking light, headlight, or turning signal can be time-consuming. Especially if you need to find the right replacement size.

Replacement options for your headlamp bulb include: Xenon Headlamp kit, High-Intensity Discharge Headlight Kit, and LED Headlights. Those for your interior lighting bulbs include SMD bulbs and LED bulbs. We’ll go through each product type and the colors available.

Xenon Headlamps [plastic headlight housings] do cost more than Halogen bulbs because they use Xenon Gas, but the benefits far outweigh the cost savings. Benefits of using Xenon Headlights include: increased visibility through a whiter light, closer color temperature to natural sunlight, and an average life of 100,000 hours (compared to 1/2 that for halogens). These types of headlights come in white and blue and you can typically find them at most stores such as AutoZone and Pepboys; however since their popularity has increased you’ll want to try online retailers for better pricing. The average price is around $6 per bulb compared to $4 for halogens.

High-Intensity Discharge (HID) Headlights consist of a blue bulb surrounded by an orange coating. It’s more expensive than Xenon headlights, but you’ll get 6X the life and visibility compared to Halogen bulbs. You can also get HIDs in colors other than blue such as green and purple; however these are specialty lights typically used only on off-road vehicles or projectors that don’t use reflectors. The average price is $12 US per bulb compared to $4 for halogens.

Our final type of headlight is actually LED headlights which actually work out cheaper than either Xenon or High Intensity Discharge lights when you consider their average lifespan is 50,000 hours. This is especially true when you take into consideration that they produce no heat whatsoever and use 1/10th the energy of HIDs or halogens. The only downside to LED headlights is that they’re typically red which means color-blind people won’t be able to see them at night.

Xenon Headlight Kits

Xenon Headlight kits are one of the most common option for aftermarket headlamp replacement. Xenon headlights are brighter, last longer, and use less energy than halogens.

Xentec HID is a popular choice among Toyota 4Runner owners. The part number for this kit is 4050300HID. This includes two pieces: an H11N high-intensity discharge (Xenon) bulb and ballast that can be wired into your existing electrical system or you can get the entire assembly installed by specialist.

The installation is fairly straight forward with almost no modification required. First, you will have to access the back of your headlight assembly to remove the halogen bulb.

After that, insert the Xenon bulb into place and secure with a new gasket. Then plug in the ballast to avoid any moisture damage. You can also purchase wiring adapters if you are planning to do this yourself.

Some users that already done HID retrofitting may also want to consider getting low beam filter for their projector lens, as it can help reduce light scatter during night driving.

Xenon headlights provides surround lighting at all angles which improves safety especially when driving around sharp curves or on hilly roads at night or inclement weather conditions.

Why not get Rid of that dull halogen headlight? Our favorite is Kensun’s HID low beam headlights .

High Intensity Discharge Headlight Kit

High-Intensity Discharge (HID) headlight kits produce a brighter and more intense light than traditional halogen headlights.

The color of light produced by HIDs is often compared to daylight, making the vehicle more visible in extreme weather conditions and at night.

One of the reasons why HIDs are becoming more popular is because they use about 35-40% less power, allowing for greater performance.

While HID lights offer superior lighting over halogen lamps, there are several downsides to these headlights.

HID bulbs run much hotter than halogens and require special cooling systems that include vents, fans and liquid cooling plates. This makes them noisier than standard headlights.

They also must be paired with a high-voltage ballast which may cause radio interference in some vehicles. While most modern electronics can easily adapt to this interference, many older cars cannot. And since the ballasts are wired directly into the headlight circuit, any problem with the ballast will render both of your headlights inoperable.

Another downside is that HIDs need a longer time to reach full brightness, which can be dangerous at night, especially for older drivers who may not be able to see as well.

Some cars with dimmer switches don’t work properly with aftermarket HID kits because the lights aren’t bright enough when turned on low beam and too dark when turned up high. Finally, even though they don’t burn out like halogen bulbs, they do suffer from shortened life spans which means you’ll have to keep replacing them every 2-3 years.

Headlight kits such as Hella’s eXtra series or Kensun’s Xenon HID kit are great options for replacement. 

Best LED Headlights

LED headlights have become increasingly popular over the last few years as a direct replacement for factory bulbs.

They’re bright, cheap, available in many colors, and plug in to your factory headlight sockets.

But when it comes to replacing the reverse lights, many people are left in the dark about how these LED bulbs can cause problems when installed incorrectly.

The issue is usually caused by installing an LED bulb with a polarity protection diode into your car’s taillight socket.

The fact that they don’t work when inserted backwards isn’t the problem; The problem comes in when you try to fix them without knowing what made them stop working in the first place.

If you’ve ever tried changing out the factory reverse light bulbs only to find that they no longer function properly after installing LEDs , this article should help clear things up .

LEDs draw less power than factory incandescent taillights. The factory reverse bulb operates on 12 volts, and draws approximately 0.1 amps (0.12 watts) .

The brightness of the LED replacement bulb similarly decreases when it’s connected to a lower voltage source. A standard LED, operating at 3 volts , is about 20% dimmer than at 12 volts .

These features make them less attractive as automotive reverse lights: The low draw means they usually aren’t bright enough to illuminate much more than your license plate, even when they function properly.

A typical taillight circuit consists of three wires running through your car’s tail light sockets: Live(+) , earth ground , and taillight filament (+).

Diode Dynamics is a popular option here . Kensun also offers high-quality LED headlights  that are DOT approved and plug in directly without any modifications needed.

Interior Bulbs

LED bulbs for your interior lighting kit may be the way to go if you’re looking for brighter lights, less energy consumption, and longer life time than stock halogen bulbs.

It is fairly common that when people switch to LED exterior bulbs they need to change their interior bulbs as well since they will no longer fit in the socket due to difference in size or connector type.

Replacement options include: SMD , T10 Wedge Base, Bayonet Base, PAR16 PAR20 PAR30 , and even the incredibly popular T20 Wedge base.

SMD LED’s are brighter than both bayonet or wedge bulbs, but not as bright as the higher-wattage ones such as PAR30 or PAR36; they fit in all standard bulb sockets with no modifications needed to your 4Runner.

SMD bulbs  are one of the most common choice for aftermarket interior lighting upgrade. They also make great side marker lights since they stick out nicely from the housing and would be perfect for that purpose.

For Toyota 4Runner owners we recommend looking into this option.
