Reverse Backup lights too dim at night? 

  • Higher output than halogen for clearer visibility
  • Stable LED design prevents flicker and early failure
  • Full metal heatsinking improves durability
  • 7440/7443 plug & play, no wiring required
  • Japanese Components with a 2-year warranty
  • - Direct Fit For:

    • 2018 Ford F-150
    • 2019 Ford F-150
    • 2020 Ford F-150
  • - Stock incandescent bulbs produce weak output with poor light distribution. Low lumen intensity reduces rear visibility, making it harder to detect obstacles, curbs, and pedestrians in low-light conditions.

The measured 500-lumen output with the top projector lens enhances focused light projection, while side illumination improves spread. This combination increases rear clarity and usable light coverage especially during night.

  • - Four-sided illumination with 12× 3030 SMD LEDs plus top-mounted high-power chip creates balanced output. This improves wide-angle coverage and direct rear projection simultaneously.

  • - Many LED claims are calculated, not measured. Verified 500-lumen output ensures accurate brightness, providing predictable performance compared to factory bulbs and unreliable competitors.

  • - Poor heat management damages LED chips our bulbs have a full aluminium housing that distributes heat evenly, protecting internal components and maintaining consistent brightness over extended use.

  • - 7440/7443 base with non-polar design installs directly into factory sockets. No wiring or modifications required, ensuring quick installation and immediate operation.

  • - Upgraded aluminium circuit board improves heat dissipation and chip protection, preventing flickering and failure while ensuring long-term durability under regular use.

  • - 90% more energy efficient than halogen and HID options.

     

    ⚠️ Note:
    7443 can replace 7440, but 7440 cannot replace 7443

Yes. 500-lumen tested output exceeds standard incandescent brightness, improving rear visibility and reversing safety.

Yes. 7443 bulbs are backward compatible with 7440 sockets, but 7440 cannot replace 7443.

Projector lens focuses light directly backward, while side LEDs improve spread, resulting in better overall illumination coverage.

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.

It depends on the vehicle and application. At Underground Lighting, the bulbs have built-in resistors, so you don't need to add an external one.
We offer other resistor options as well.

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.
