7443/7444 Red LED Brake Light and Taillight Bulbs

Our ultra-bright 27W, 1600LM 7443/7444 brake light and taillight bulb is built for parking, brake, and turn signal use, delivering deep red illumination across a full 360 degrees.

Unlike other brands that place resistors on both filaments (which can cause the housing to melt or LEDs to fail), our 7443/7444 LED brake light and taillight bulbs have a built-in resistor only on the turn signal filament.

To make them last longer, we have added a cooling fan that activates only when the high filament is turned ON, cutting heat during resistor use and keeping the LED away from constant heat exposure. This is what keeps hyper flashing and error codes off your dash, and it's a direct replacement for your factory incandescent bulb, no separate resistor or extra parts needed.

Best-in-Class Brightness

Each 7443 red LED bulb features 12 high-performance 1860-style deep red LED chips, putting out 1600 lumens. That means your turn signal bulbs and this red LED brake light bulb will run noticeably brighter than a stock incandescent bulb.

Reliable Compatibility

Whether it's a 7443/7444 brake light bulb or a 7443/7444 tail light bulb with a built-in resistor, it works with 99.8% of vehicles without any issue. However, a small number of systems with highly sensitive onboard computers may need special handling.

Installation

Difficulty Level: Beginner
Installation Time: About 10 minutes
Type: plug-and-play, no splicing or complex wiring required

Turn off the vehicle, access the rear light assembly, remove the old 7443 bulb, inspect the socket, and push the new LED firmly into place. Test the tail, brake, and turn functions before reinstalling the housing. For the complete procedure, follow Underground Lighting’s step-by-step 7443 brake light installation guide.

Yes. 7443 and 7444 bulbs share the same dual-function T20-style base and can generally be interchanged when the vehicle socket supports both. However, always verify the vehicle’s original bulb number, socket, electrical configuration, and required brightness before replacing one with the other. This Underground Lighting bulb supports both 7443 and 7444 applications.

The 7443/7444 Red LED Brake Light & Turn Signal Bulbs cost $64.99 for a pair. Each bulb produces 1600 lumens and has a built-in resistor, so no additional resistor is needed for the turn signal circuit.

A red 7443 LED is recommended for brake and tail lights behind red lenses because it preserves strong, pure red output instead of relying on a white LED filtered through the lens. For turn signals, the required color depends on the vehicle’s lighting setup: use red for red signals or amber where amber output is required.

Generally, yes. 7443 and 7444 are dual-function bulbs with compatible T20-style bases, so they can often be substituted. However, compatibility depends on the vehicle’s socket, wiring, factory lighting configuration, required bulb specification, and lens/color requirements. Check the original bulb number before ordering. For related bulb differences, see Underground Lighting’s 7443 vs. 7440 LED bulb guide.

A 7443 brake light bulb handles the brake light, parking light, and turn signal, all from one bulb. It's one of the most common bulb sizes used across brake and tail light applications on modern vehicles.

A 7444 bulb is essentially the same size and function as a 7443, just built with a slightly different internal wiring configuration for certain vehicles. Both fit the same socket, so this pair works as a direct replacement whether your vehicle calls for a 7443 or a 7444.

7443 taillight bulbs come with a long lifespan. They can run 50,000 to 100,000 hours of light, much higher than the Incandescent bulbs which lasts around 750 to 2,000 hours.

Yes, provided your vehicle uses a compatible 7443/7444-style bulb and socket. The bulb can perform the functions required by the compatible factory application, so it does not need every vehicle to use all three functions. The key requirement is matching the correct bulb number and electrical configuration.

2016 Chevy Silverado 2500HD

Installation was smooth and easy and very bright and works great! I did notice that if you are stuck in traffic and moving slowly, they will hyper flash but doesn't last long. Love them!

Superb quality

After a lengthy R&D process on a modified harness, I now have 2023 ram halogen tails in my 2012. I like the look of the halogens vs the factory led. But the standard bulbs are lackluster. After your bulbs weee installed, it was perfect. Crisp, clean, and very bright!!!

Review LED’s with resistors

Happy with them & no hyper flash,as soon as i purchased i was given a better discount offer which is consumer conflicting as to why not offer tge better discount which leads me to believe the originsl price was high in order to profit more so off of unsudoecting condumer/customers….I dont want to give a bad review on socisl media or consumer reports like Yelp but thats why those are available to consumers to inform others as in a condortium of sticking together to hrlp one another,by word of mouth will always be the #1 form of advertisement bar none…power in the people🙏🏼

Blows The Stock Halogens Out Of The Water!

These LED backup/ brake light bulbs are extremely bright and are so much better than the stock halogen bulbs.

Very bright lights

7443/7444 Red Brake light Bulbs

I've been using these in our 2017 Enclave and Ram for years. The amber front turn bulbs and the reverse light bulbs as well.

They are amazing. No hyper flash and extremely bright (they actually cause the reflective street signs to flash from many car lengths back from the intersection). OEM bulbs? No comparison.

If you want LED's and don't want the hyper flash or a resistor wiring job, get these. They will exceed your expectations.

Awesome!

Brighter than factory, and as advertised, no hyper flash!

They WORK!

So far, so good. Just installed and tested them in the driveway and no issues, no hyper-flash! Now I just need the bulbs for the FRONT turn signals!

No resistors needed

I was very skeptical about these LED lights. This would have been the 3rd brand I’ve tried. The other brands say they would work in my Chevy Silverado. They didn’t!! However underground lights hold true to the description about these LED lights. They work great and absolutely no hyper flashing. I would recommend if you are changing from halogen lights to LEDS.

My third purchase from Underground and as usual NOT disappointed. I have recommended them to my friends and all have been extremely satisfied. LED high and low head light replacement perfect. Third brake light cargo light very bright. And now reverse light and brake light very bright. Simple simple simple! Highly recommend.

Blazer lights are blazing

Installed 7443/7444 brake/turn signal bulbs and they look great! No codes and no issues. Hopefully the cooling fan makes the difference over time, as all the others failed after a few months. Great looking product and great service too!

Error, free, red LED break and turn signal

These error free taillights are absolutely amazing. No splicing wires and adding resistors. I wish they had this technology out 10 years ago. Direct plug and play about a five minute install.

Excellent quality

These are the 3rd set of lights I've bought from this company and you have a lifetime customer! They do not hyperflash and are bright! They are in both of my vehicles and I love them.

Shipper quickly. No hyperflash, just as stated. Definitely a big upgrade for my rear signals.

Pricey but perfect it and great performance

Bright brake light bulbs.

So far so good these are much brighter than my stock bulbs and work properly in my 2025 GMC.

Good

So far, so good. Seem to work as advertised.

Excellent customer service

Order placed promptly. Received phone call to confirm shipping choice. Parts arrived on time and worked as described. No hyper flash or warnings when installed on brake lights in 2024 GMC Sierra elevation. Thank you!

Way brighter!

So far so good! I just really hope they don’t hyper flash after having them a while!

Break light

I hope that they last longer than the other ones I had bought, from a different company, these seem great, just kinda pricey

Beyond bright!

Highly visible even through smoked lenses!

Awesome

Totally awesome brightness and no hyper flash or can bus errors.

Help I can’t see

I purchased replacement LED lights for my Silverado just the tail and back up lights … after installing I had my darling wife help me check to make sure they were working properly.. right bilnker ..left.. tail … and the back up..they were so much brighter I had spots in my eyes …I’m a returning customer and have bought various other lights from Underground.. they a shipped fast ..and if you call the customer service they answer.. a real human .. with answers.. every time I buy a new car or truck I install bright LED lights because you really can’t have enough light … the next car I will buy again from Underground

Amazing lights. Super bright. Fit very snug. Love them

The fan is very loud when I step on the brakes. Is that normal?

Underground Lighting

Some taillights the fan will echo. Try flipping the bulb 180 degrees.
