Product Details

2014-2021 Toyota 4Runner LED Low Beam Bulbs: Looking for upgraded LED Low Beam Bulbs from a reputable brand and value the fact that we've actually tested them on your truck? Our HR Tested kits include all the right components to ensure perfect fit, function, and performance from the upgrade. At Headlight Revolution, we do 2014-2021 Toyota 4Runner LED lighting upgrades better!

The GTR Lighting CSP Mini LED bulb: was designed with two main ideas in mind: #1: Perfect Fitment into any fog light housing - specially designed to closely mimic the size and shape of your original halogen light bulb for maximum capability! #2: Perfect Beam Pattern due to the alignment and design of the low-profile copper PCB and Philips Z ES "CSP" style LED chips.

This LED configuration: creates a similar light output profile as compared with the original filament bulb for an accurate beam pattern.

Heat Sink Technology: No Fan Noise! Fans work well to cool down powerful LED fog light bulbs, but the GTR Lighting CSP Mini is unique blend of power and efficiency that does not require active cooling. Coming in at only 16 watts of power, and featuring the Philips Z ES high-efficiency chips, these bulbs create about 2 times as much light as your original halogen bulbs at less 33% less power consumption. In short, they're super efficient so they don't need a huge fan mounted to the heat sink to stay cool! The powder-coated aluminum body of the bulb acts as the heat sink for both the internal driver and the LED bulbs themselves.

Thermal Management: The GTR Lighting CSP Mini LED bulbs are equipped with a sophisticated thermal protection circuit to avoid failures due to overheating problems. We've tested these bulbs at 194 degrees Fahrenheit for 15 days straight without failure! The maximum power draw of these bulbs is 16 watts of power and if the LED thermister sensor reaches a temperature of 140 degrees Fahrenheit or hotter the temperature protection kicks in and reduces the light output to a safe level. This smart technology allows the bulbs to never get so hot that they burn out the chips, which is the most common reason for LED bulb failure. Even at a reduced level of 13 watts of power consumption (to prevent over-heating...), the GTR Lighting CSP Mini LED fog light bulbs will still be noticeably brighter than your old halogen bulbs! This function happens 100% automatically and ensures the longest possible lifespan of your fog light bulbs!

Furthermore: the GTR Lighting CSP Mini LED fog light bulbs are equipped with the highest quality possible chip technology. We use the genuine Philips Z ES "CSP" style LED chips that have a higher heat-resistance rating than other similar versions. Beware of imitators! If someone is selling a bulb that looks like ours, make sure they're using the good chips like Philips ZES! These LED chips are rugged, heat-resistant and create the tightest optical source for the best beam pattern. Your fog light bulb LED chips really do make a difference!

Brightness: Your original halogen incandescent fog light bulbs produce roughly 1,000 Lumen per light bulb, at about 55w of power consumption. The GTR Lighting CSP Mini bulbs produce 2,500 Lumen of light at only 16w of power consumption! Not only do these bulbs have the ability to be 2-3 times brighter than your old light bulbs, in most applications they will also mimic the OEM beam pattern to protect other drivers' vision at night!

Want your fog lights: to shine brighter and further but your current bulbs just aren't cutting it? Want to get rid of that old yellow tinted light and give your ride an updated look with a cool white light beam? Look no further! Built with high power premium quality Philips Z ES LEDs, these LED fog light bulbs will cast a precise light beam that will give you increased visibility, a wider viewing angle, and a much longer Limited Lifetime over conventional halogen bulbs. The bulbs feature great heat management with 1070 aluminum construction, Intelligent Thermal Management, and the newest "CSP" style LED chipset from Philips.

Fitment: Match the bulb number of your original application (example: 9005, 9006, H4, H13, etc...) with the matching GTR Lighting CSP Mini LED fog light bulb and replace bulb for bulb. Fits all applications including projectors, and fog lights with dust shield covers.

NOTICE: If your vehicle uses a CAN BUS system to operate the fog lights, you may need additional parts like an LED CANBUS or PWM module. Contact us for details if you are unsure.

HR Tested: Here at Headlight Revolution, we've spent the time to install and test all HR Tested products, so we know it'll work exactly as shown and right out of the box!

Nice plug and play LED bulb


Easy plug and play bulb on 2018 4Runner. Not the brightest of the options but still an impressive upgrade from stock. I installed in fog lights as well and that was a dramatic difference in terms of light output and road visibility. The 6000k color takes some getting used to after running stock halogen bulbs, but give it some time to let your eyes adjust.

Great upgrade

I installed these to upgrade my 4Runner low beams. I didn't want to modify anything or drill holes these fit perfect plug and play. I think I might get the high beam kit too.

Much Brighter - Decent Beam Pattern


Overall, high quality bulb and easy to install. I had these in my vehicle for about 8 months before having to remove them due to the beam pattern. I installed them exactly as described however I found many "gaps" in the light on the road, specifically closer to the vehicle. The gaps or dark spots became a bit to distracting to me so I switched them out and went back to a brighter halogen (for now). I don't think the less than stellar pattern is just these bulbs, but likely all LED's right now. If you are looking for much brighter lights this is a great option however if you're very particular like me about beam pattern maybe consider a nice HID or high quality halogen. I wouldn't hesitate to recommended the bulbs and HR even though I was slightly disappointed.

S-V.4 perfect fit.


Bulbs had too much of a blue color than what I was expecting. Wish they were more white in color. Not as bright as I would like. Overall not terribly but not great.

Great led lights


First of all thank you to the staff for the help and answering all my questions with out getting upset like other places. The S-V.4 perfect fit low & high beam are super bright and easy to install. I highly recommend this light and any product from them.

4runner S-V.4 perfect fit


I have been having issues with the stock Halogen bulbs burning out every year or so. I Decided to try LED's this time. I must say I am impressed definitely brighter that stock. Nice clean beam pattern. Super easy to install. Build quality was excellent.

Great for an LED, but there are better options... for me.


First off, these are probably as good as it gets for an easy, direct fit LED "bulb" insert.

They are indeed a bit brighter than stock, especially in the "garage test". They actually look way brighter against a wall than OEM long life bulbs.

On the road is where these fell apart for me.

Personally, they are too blue. They look pretty from the front, but driving behind them... I find I prefer a "yellower" light. They almost make yellow center lines look green. Again, this is merely a personal quibble. I've seen way worse looking lights.

The pattern they throw is quite even and I was quite impressed by this quality. The cutoff appears excellent, too. I might've been very happy with these if I liked the color and didn't plan on testing them against a nice halogen bulb...

A Philips Xtreme Vision or Osram Night Breaker Laser bulb works so much better for ME.

Mostly, the Philips/Osram halogen beam spread seems greater and it looks like they throw a bit further to my eye. The halogen light color seems easier on my eyes for some reason. The bluer LED color almost hurts after a while.

In summary, the S-V.4's are great for an LED option! I just don't care for them when compared to a nice halogen.

I would think these LEDs would be best suited in a fog beam application for their close range brightness and beam/cutoff quality... but I like yellow fogs.
