Engineered Solution: Thanks to the smaller than usual footprint of the 4Bangers, we now have a powerful fog light upgrade that fits properly and looks right on the 2021-2023 F-150. Other adapter kits for more traditionally sized LED pods stick out like a sore thumb. Not here. Morimoto engineers spent hundreds of hours hands-on in the garage during development of the Banger brackets alone, and fitted bezels make the finished result look truly factory. Super Wide Output: The factory LED fog lights on these trucks perform well, but the aftermarket can always do better. The 4Banger optics feature dual axis control: 1) for width, and 2) active hot spot control to project peak intensity right along the top of the beam pattern. The proper vertical gradient and powerful Nichia or Osram LEDs make these the brightest SAE-Compliant fog light pod on the market today (Photometrics are third-party verified SAE Compliant by Calcoast ITL). The 4Banger SAE Wide beam delivers the best combination of width, intensity, and control -- making it the most effective on and off-road LED fog light in the world. NCS or HXB: Morimoto 4Banger pods are available in two tiers of performance: NCS (for Nichia NCS LEDs) or HXB (for Osram HX Boost LEDs). NCS pods produce 1,300 raw lumens each, whereas HXB produce a whopping 3,000 raw lumens each. Either way, they’ll far surpass your stock fog light output! All Weather: The optional, white-output version is ideal for all-around visibility. For those who desire optimal output in rain, snow, or fog--the Yellow-output version will slay in shady weather. Easy Setup: Everything is designed to bolt-on and plug-n-play. No modifications are required to your vehicle or its wiring to add 4Banger pods in place of your factory fog lights. Each kit includes all the necessary hardware and high-quality wiring adapters to connect with your factory fog light harness. If your truck has LED DRLs in the fog lights, the two optional relay harnesses allow retention of the active turning L/R function. For trucks without these, only one relay harness is needed. Fully Adjustable: These things are powerful, and while their wide beam pattern is perfect for use as a fog light, power is nothing without control. All brackets have +/- 6 degrees of vertical adjustability so that you can dial in the aim and ensure every ounce of intensity ends up on the road ahead, not in the eyes of oncoming traffic. This wide range of adjustment allows proper aim whether your truck is lowered, lifted, or stock height. Air Cooled: As if the style, the fitment, the adjustability aren't enough: we have incorporated duct work into each bracket to actively cool the LED pods while you drive. This improves lumen maintenance by eliminating heat-soak, which is common in other LED pod fog light kits that have no ventilation for the heat sink.
