Poor visibility in rain or daylight glare?

  • 300% brighter than halogen for clearer signalling
  • Built-in resistor eliminates hyperflash instantly
  • Advanced cooling extends lifespan up to 10× longer
  • 7443 LED plug & play, zero wiring required
  • Designed in the USA, assembled with Japanese components

2015-2018 Ford F-150 Front Turn Signal Bulb Replacement

Upgrade your dim or faulty 2015 Ford F-150 turn signal bulb with a brighter 7443 LED designed for the compatible front turn signal application on Ford F-150 series vehicles. Each bulb produces 1200 lumens through 54 SMD LEDs, giving the front signal a broad 360° light pattern.

Our 7443 bulb with built-in resistor handles the turn signal load inside the bulb, so you don't need to install a separate resistor or modify the factory wiring. CANBUS, nonpolar, and CK-compatible electronics keep the upgrade simple.

Built-in Resistor for No Hyperflash

Switching from a factory halogen bulb to an LED can cause rapid flashing because LEDs draw less current. The built-in resistor adds load specifically to the turn signal circuit, helping maintain the normal flash rate without an external resistor.

The resistor is used only for the turn signal circuit rather than both circuits. This limits unnecessary resistance and heat during normal operation.

1200 Lumens With 360° Amber Output

Each F-150 front turn signal bulb uses 54 SMD LEDs to produce 1200 lumens with a 360° beam pattern. The broad output distributes amber light across the factory housing instead of concentrating it in one direction.

That gives your  2015-2018 Ford F-150 front turn signal bulb brighter, wider light output while maintaining the required amber signal color.

7443 LED for Ford F-150 Turn Signals

This LED uses the 7443 bulb configuration for the compatible F-150 front turn signal and DRL application. The design provides a direct-fit LED option for the compatible factory socket on Ford models like the 2015 Ford F-150, 2016 Ford F-150, 2017 Ford F-150 & 2018 Ford F-150.

Built-in Cooling Fan with bulb

The LED assembly combines a full metal heatsink with a built-in fan to manage heat during operation. Active cooling helps maintain stable light output during repeated turn signal use.

The cooling system is built into the bulb. It extends the lifespan of the bulb by continuously dissipating heat.

Plug-and-Play Installation

Replacing the 2015-2018 F-150 front turn signal bulb takes approximately 10 minutes. Remove the factory bulb, install the LED replacement, reconnect the socket, and test the signal.

No cutting, splicing, or complicated wiring is required.

 2019 is a split year—both types exist depending on trim

7443 and 7444 bulbs are not exactly the same, although they are very similar in design and function. Both bulbs are dual-intensity and are commonly used for tail lights and brake lights. However, the 7444 bulb generally has a slightly higher wattage and brightness output compared to the 7443 bulb. They are often interchangeable in many vehicles, but it's always best to check your vehicle's owner manual or use our Vehicle Finder Tool to ensure the correct fitment and compatibility.

Installing 7443/7440 LED bulbs is straightforward:

  1. Safely remove the old bulb from its socket.
  2. Plug the new LED replacement bulb into the existing socket.
  3. Test the light to ensure proper operation.
  4. Secure the housing and enjoy your upgraded lighting!

Some vehicles, especially Canbus systems, may need load resistors to prevent hyperflashing or error messages. Underground Lighting offers compatible resistors for proper functionality.

Yes, 7443/7440 LED bulbs are significantly brighter than halogen bulbs. They provide sharper illumination, improving visibility and safety on the road.

7443 and 7440 bulbs aren’t interchangeable because they have different socket configurations and functionalities. Make sure you select the correct type for your specific lighting requirements.

No LEDs run cooler than OEM bulbs and will not harm or cause any damage to your wiring harness or housings. And our LEDs have an advanced cooling system, making it efficient and durable with a lifespan of 25k+ hours

No, the LED does get hot, but not as hot as an incandescent bulb.

Did you start the engine before testing? The vehicle engine must be on and running for the BCM to turn on for the load resistors to be detected. Read the Hyperflash guide & know the details
