LED Tail Light Bulbs with Resistors

7443/7444 Red LED Brake Light Bulbs – Description and Overview

Best Performance in Industry. Our Ultra Bright 27W 1600LM 7443/7444 Parking/Brake and/or Turn Signal Light Bulbs LED W/Built-in Resistors No Hyper Flashing (2 Pieces) are Deep Red colored type LED lights that cover 360 degrees to provide maximum output. Unlike other brands, with resistors on both the filament, we created a CANBUS LED that only has a built-in resistor only on the turn signal filament. Having a resistor on both the filament will lead to melting the housing or the LED falling apart in the housing. We even took it one step future to ensure the longevity of the bulbs by adding a cooling fan. The fan only turns on when the high filament is engaged, to reduce heat when the resistor is on.  Our Design protects the LED from being exposed to constant heat eliminating this issue. This assures no hyper-flashing or error codes. Our LED is designed to replace the factory incandescent bulb without the need to add extra resistors or parts.

Best-In-Class Brightness. Each LED is equipped with 52 SMD LEDs Deep Red Colored type LED lights 360 degrees to provide the max output. Each bulb is 1600Lm, your turn signals will shine a lot brighter than the stock incandescent bulb.

You’ll be hard-pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these bulbs feature an impressive 52-deep red color LED chip design.

Will work on most vehicles. Some vehicles have really picky computers and might not accept a LED. Works on 99.8% Of vehicles.


    Difficulty Level: Beginner - Simple Installation for anyone.

    Installation time is approximately 10 minutes. There is no need for slicing or complicated wiring. This light is a plug-n-play installation and operation.

      Frequently Asked Questions on LEDs

      Will LED Bulbs Damage My Car?

      No. LEDs will not damage your vehicle if properly installed. In addition, you want to purchase the correct LED light that will fit your car. For example, if your vehicle has a CANbus system, you want to buy the right product and install it correctly to avoid any potential issues.

      If your car was not originally designed for LED Bulbs, you can purchase a LED bulb and install them. They are safe and will not damage your vehicle as long as you buy top-quality products.

      Why Are LED Lights Better?

      An LED light bulb saves more energy, produces less heat, and has more light. In addition, it uses 85% less electricity than standard lighting. It is also a lower-cost product but has bright light with a longer life span.

      LED light is different from incandescent light. Blue LED combined with yellow phosphor creates white light. The high efficiency of LED light makes it a popular choice.

      What Is the Lifespan of LEDs?

      LEDs have a long life span. When an LED is operating at 70% capacity, it has reached the end of its life span.

      Incandescent bulbs have around 750 to 2,000 hours of light. In comparison, LED bulbs can have 50,000 to 100,000 hours of light, making them better investments.

      Can I Replace Incandescent Bulbs with LED in My Car?

      Yes! You can change your initial bulbs to LED in your vehicle. In addition, there are different places where you might want to swap out for LED lights. For example, you can change your headlights, rear license plate lights, interior door entry lights, rear brake lights, and more.

      First, however, you need to inspect what type of bulb you need. There are different bulbs with various designs, so you must buy the right one to fit.

      Second, different areas of your car may require special tools or specific parts to work properly. Once you have found the products you need, you’re ready to go LED.

      Frequently Asked Questions about Turn Signal LED Bulbs (FAQ's)

      Which color LED is best to install in my red lens taillight?  

      Red LED is the best option to put in a taillight with a red lens. Red will give you a nice deep bright red color. Where white would make the light output look like a soft pink. 

      My rear Brake light is also my parking light and turn signal will your LED work for all 3 functions?

      Yes, as long as you buy the correct part number our led bulb will do all the same functions that your OEM bulb did.

       Are LED light bulbs good for eyes? 

      Many people worry that the increased brightness of LED headlight bulbs will result in a shine that is too bright for others on the road. However, we feature lights that are specially designed to focus light in a way that will not blind oncoming traffic. Your Red LED lights from Underground Lighting contain the perfect balance of brightness, style, and safety on the road.

      What is hyper flash and what causes hyper flash?

      Hyper flash is where the turn signals or indicators on a vehicle blink at a much faster rate than normal. This can be caused by several factors:

      • Bulb Failure: The most common cause of hyper flash is a burnt-out or malfunctioning bulb in one of the turn signals or hazard lights. When one of these bulbs fails, the system detects a lower load on the circuit and increases the flash rate as a warning to the driver.
      • Installing an LED Bulb: When replacing traditional incandescent bulbs with LED bulbs in vehicles that were not designed for LEDs, you might experience hyper flash. LED bulbs use less power, and the vehicle's flasher relay may interpret this as a burnt-out bulb.
      • Faulty Flasher Relay: The flasher relay is responsible for controlling the rate of blinking of the turn signals. If it malfunctions, it can cause hyper flashing or erratic blinking. Replacing a faulty flasher relay can resolve this issue.
      • Wiring Issues: Damaged or corroded wiring can disrupt the electrical flow in the turn signal circuit, affecting the flash rate.
      • Incorrect Bulb Type: If the wrong type of bulb is installed, it can draw too much or too little power, leading to hyper flash.
      • Resistance Issues: Some vehicles use a variable load sensing flasher relay, which can detect changes in resistance. When adding additional lights or modifying the wiring, you might change the resistance in the circuit, causing hyper flash.

      Why do I have hyper flash on the dash after installing LED turn signal bulbs?

      LED bulbs draw a lot less power and current making the Body Control Module think the bulb is out.

      Why do I still have hyper flash after Installing Underground Lighting LED turn signal with built in Resistors?

      The most common reason is basic mistake many make. Make sure you start the vehicle and let the engine run before testing your turn signal for hyper flash. Starting the engine turns on the BCM so the computer can see the resistance in the bulb.

      Do I need to have Underground Lighting Led turn signals in the front and rear to not have hyper flash issues? 

      The short answer is no, you don’t. However, you need to have resistors on every turn signal bulb that doesn’t have resisters built in. The front and rear turn signals are tied together so you can not have resistors in the front and not the rear for example if both front and rear are LEDs.

      No hyper flash and bright

      I had terrible luck with Amazon bulbs that claimed to have built in resistors. All caused hyperflash and warning light on the dash. These work great and the fans are very quiet. Some of the Amazon ones with fans were so loud you could hear them INSIDE the truck!

      Work great just what I was looking for!

      Bright red, absolutely no hyper flash, easy plug and play install, I will say that the bulbs are a little bigger then I excepted be sure to refer to tech specs to make sure this will fit your application. These work perfect

      These bulbs work great in my Silverado. They do not hyper flash like others I have tried.
