Morimoto GMC Sierra HD (20-24) BigBanger LED Ditch Light System
Morimoto BigBanger LED Ditch Light System — GMC Sierra HD (2020–2024)
The BAF145 BigBanger kit is the long-range end of Morimoto's ditch light range for the Sierra HD. Two beam patterns — Combo and Spot — are offered in both NCS and HXB pods, in white or yellow output. Combo balances width against distance; Spot penetrates up to 800 meters.
The A-pillar brackets are laser-cut from 304 stainless steel and powder-coated, and they install on a 2020+ Sierra HD without modifications. Potted internals, over-molded wiring, and main gaskets carry an IP69K weather rating.

Will this fit my Sierra HD?
Yes. The A-pillar kit is engineered for seamless fitment on 2020+ GMC Sierra HD trucks and installs without modifications.
Should I run white or yellow pods?
White output gives ideal all-around visibility. Yellow excels in rain, snow, or fog — Morimoto uses phosphor-converted yellow LEDs that generate yellow light at the source, which penetrates airborne particles without sacrificing output.
Combo or Spot?
Combo balances width and distance illumination for driving in remote areas. Spot penetrates up to 800 meters for long-range visibility.
Do I need a wiring harness?
The pods route their input wiring into the engine bay via cable routing clips and are plug-and-play with Morimoto's switched relay harness, which is purchased separately.
