Frequently Asked Questions

Will the 20-50” FLEX ERA® LED Light Bars come pre-assembled?

No. Regardless of if you buy a 20”, 30”, 40” or 50” bar, they will not come preassembled. But don’t worry! The inside of the box itself contains a full, true-to-scale assembly guide to ensure you get it done quickly. Even better - we included all of the tools necessary for installation. Grab a beer and get to work, it shouldn’t take too long at all!

How do I link the segments together?

The ends of each 10” segment are universal in that they can accept either and End Mount Bracket or a Linker Bracket. Just make sure that you put the Overmolded Power Linker on prior to the main bracket! Use the included hardware and go snug without overdoing it.

How do I change the bar from straight to curved?

At each junction point of two 10” FE Bar segments, the linker bracket has two options for where to place the set screw that determines if the bar is curved or straight. Place the smaller countersunk bolts into the holes shown below on each junction to make it to your liking.

Screw placement for straight versus curved bar

Is the FE BAR based on the FLEX ERA 1 or FE4?

Not exactly. While it might look similar in size to the FE1, it’s an entirely new product. The bezels and shields are not interchangeable. In fact, the FE Bars have very similar performance to a single FE4 light due to the use of similar optic components, just in a different configuration. This product is a complete reimagination of the previous FLEX Array Bar, that stays true to the FLEX ERA Family of products.

What are the extra lenses that are included in the FLEX ERA® LED Light Bar boxes?

Each box of FLEX ERA® LED Light Bars lights come standard as a Master Kit, which includes all beam pattern lenses that are available. The lights come preassembled with the Combo Beam lenses (vertical lines ends of the lens). There are also Spot Beam Lenses (complete clear appearance) included in the kit.

When should I use the included spot beam or combo beam lenses?

For those that desire the furthest possible distance out of their light output, the Spot Beam lenses will perform best. For those that want short to mid-range distance coverage while also having more horizontal coverage, the pre-assembled Spread Beam lenses will be best.

Since the lens is designed to be swappable, how does this impact the warranty should anything happen? E.g. if water ingress occurs due to user error while swapping the lens?

Our standard KC Adventure Further Guarantee applies to these lights. We encourage you to swap out your lenses to see what works best for you - just do so in a clean and controlled environment. Feel free to check out our installation videos for best practices or give us a call and we'll be happy to assist!

What are the differences between the Amber Shields and the Performance Yellow Lenses?

While both enhance visibility in poor visibility conditions, Amber Shields will excel in extreme conditions like highly dense dust or silt, with their darker hue minimizing glare. On the other hand, our Performance Yellow Lenses offer a purer, brighter yellow output, making them great for a broader range of conditions from dust to wide-open and clear environments. In addition, the Amber shields simply snap over the face of the light, while the Perf Yellow Lenses will entirely replace the clear spot or combo beam pattern lens. Combo Clear and Spot Clear lenses come with the Master kit. All Performance Yellow lenses are sold separately.

What is the difference between the FLEX ERA® LED Light Bars and the discontinued FLEX Array Light Bars?

  • The FLEX ERA® LED Light Bar is the replacement for the discontinued FLEX Array Light Bars. We took sizing, styling, and feature-set cues from the original, and evolved the light in every single way possible.
  • A single 10” FE Bar features 108W and 7,912 lumens of output compared to the older FLEX Bar which was 50W and 4,875 lumens per light.
  • The FE Bar is fractionally larger in all 3 dimensions than the FLEX Array was, allowing for deeper and larger reflectors for groundbreaking performance.
  • Finally, the FLEX ERA® Bar features an Amber LED Backlight for a bit more styling.

Are there options for colored bezels beyond the gold one on FE Bars?

Absolutely! Customization and personalization is as core to the FLEX ERA Family as performance is. We also offer the bezels in 10” segments of red, blue, and black bezels.

Do the FE Bars include an amber backlight?

Yes. The FLEX ERA® Bar still has the main power circuit for the full brightness mode, and also uses a second power circuit to offer the Amber Backlight.

Do the FE Bars include blackout covers?


Can I use light locks with the FE Bar?

Yes, light locks are compatible with the FLEX ERA® LED Light Bars. Use SKU 7222 aka the M8-1.25 Light Lock Security Nut Set for the main end mount, and SKU 7223 aka the M10-1.5 Light Lock Security Nut Set for the bottoms of the L-Brackets. But remember, don’t lose the included key! Otherwise you’ll have a fun evening with an angle grinder if you ever need to remove the lights.
