The Heretic 40" LED light bar is a beast of a light when it comes to LED light bars. They truly turn darkness into light. These high performance 6-series clear LED light bars are housed in CNC machined aircraft-grade aluminum, and outfitted with best-in-class circuit boards that allow temperature control and long-lasting light. The 40” LED  light bar is recommended for forward-facing applications in aftermarket roof racks like PRINSU and UTV roll cages. This light bar is best for visibility on clear night conditions. With the bracket included this is a 42"LED Light Bar.

Spotted from space!

Quality, craftsmanship, light output, all are easily 10 Stars! This lightbar by far shoots farther, is brighter, and better quality than anything else I’ve seen on the market. Really stands out amongst the crowd at local meets. At this point you’ve spent too much time reading this when you should have purchased already! Cannot say enough good things and will for sure be a repeat customer.

Lots of light!

Got the Heretic 40" Light Bar to go with my TrailRax rack for my Bronco. Install was pretty straightforward, I followed the Heretic video and connected it directly to one of my upfitter switches. The bar is super bright, at some point I plan to add the Heretic fogs (and maybe ditch too) to complete the look. Pricey, but the quality is really nice, and I think it's one of the best looking low profile options.

Special Mounts for Heretic 50" Light Bar for 1995 Defender 90

Going in, I knew the original brackets that came with the 50" light bar will not work on the exterior roll cage of my fully restored 1995 NAS Defender 90. So I contacted my good friend and owner of Piedmont Metal Fabrication, Bob. He designed, machined and anodized these beautiful brackets. He even machined a tunnel for the wiring. From a distance, the light bar looks like it's just floating. Very pleased with Heretic Studio's slim design, super bright light bar and the custom mounting brackets by Piedmont Metal Fabrication. email:
