Weak signal visibility in daylight or rain?

  • 300% brighter than halogen for clearer signalling
  • Built-in resistor eliminates hyperflash instantly
  • Advanced cooling extends lifespan up to 10× longer
  • 3157 plug & play, zero wiring required
  • Designed in the USA, assembled with Japanese components

Why does this LED Turn Signal for Ford beat everything else?


  • - Direct Fit for 1997-2014 Ford F-150, 250, 350 Models, check compatibility for fitment details.

  • - Sunlight glare, rain, and fog reduce signal contrast. 1200-lumen LED output improves visibility, helping oncoming and adjacent drivers react faster as compared to ~300–400 lumens Halogen bulbs' output.

  • - Amber Color Option - Best color option for turn signal bulbs as it's a legal mandate in multiple states and produces a crisp light

  • - 54 SMD LEDs produce 1200 lumens across a 360° beam angle, ensuring visibility from front and side angles. This improves lane-change signalling, intersection awareness, and driving safety.

  • - Dual-intensity circuit supports low-output DRL and high-output turn signal modes, switching instantly for clear signal separation and consistent operation without flicker or overlap.

  • - LED bulbs draw lower current than halogen bulbs, triggering rapid blinking. Built-in resistor simulates factory load (~60–120 flashes/min), restoring correct flash rate without external resistors.

  • - Excess heat reduces LED efficiency and lifespan. The fan + metal heatsink system regulates temperature, maintaining stable brightness and extending lifespan up to 10× longer than halogen bulbs.

  • - Designed in the USA and built with Japanese components, ensuring durability and precision. Improved thermal and electrical stability delivers consistent 1200-lumen output and long-term reliability.

Yes. OEM-spec 3157 base ensures proper locking and contact alignment. Dimensions (2.4" length, 0.83" diameter) are optimised to fit factory housings without looseness or instability.

Installing 3157 and 3156 LED bulbs is a straightforward process. Start by turning off your vehicle and removing the old bulb from its socket. Then, carefully insert the new LED bulb into the socket, making sure it's securely in place. You need to test the bulb to confirm it works correctly before reassembling any components, and always handle the bulbs carefully to avoid damage. 

If you come across any issues like flickering or non-functioning bulbs, check for compatibility or use a load resistor to resolve electrical inconsistencies. For easy installation, check your vehicle’s manual and the bulb manufacturer’s guidelines. 

Yes! The 3157 LED bulb is the dual filament option for the 3156 LED bulb, and you can easily use it in the same socket. The two will work together seamlessly to instantly upgrade and update your older, dimmer Halogen bulbs with the unmatched brightness of an LED Turn Signal. However, a 3156 bulb can’t work in a 3157 Socket.

  • Check owner’s manual bulb chart
  • Remove existing bulb: 3157 = dual-filament wedge base
  • Match with front turn signal/DRL circuit specification

Yes. Dual-intensity output maintains reduced brightness in DRL mode, preventing glare while ensuring visibility, and switches to full intensity during turn signal activation.

Yes. Circuit prioritisation ensures DRL dims or turns off instantly, with no flicker, overlap, or inconsistent behaviour during turn signal operation.

Amber output remains consistent in color, with lower intensity in DRL mode and full brightness during signalling, ensuring clear contrast and visibility through clear lenses.

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
