Nilight 90021H Horizontal Bar Clamp Mounting Bracket Kit for Off-Road LED Light Bars (8-Pack) – Black
Product description
If you want your off-road LED light bar mounted solidly without extra drilling, this Nilight horizontal bar clamp bracket kit is designed for the job. It’s a practical solution for roof rack and roll cage setups where you’d rather secure the bar around a tube and keep things clean.
The essentials
This kit uses a clamp-style approach with horizontal bar mounting brackets. The company positions it as a rugged aluminum-alloy setup that holds the light bar firmly, while rubber inserts help dampen vibration—useful when roads get bumpy and you don’t want the bar rubbing against metal.
There’s also a “no-drill” mindset here: it references pre-perforated holes so you can add lights quickly with the provided Allen hex key. Not every vehicle setup will be identical, but on paper, this is the kind of mounting hardware that helps you move from “idea” to “installed and running” with less hassle.

Key things to consider before buying
The most important detail is fit: the description says the clamps can be used on tubes with diameters of 1 inch, 1-1/2 inches, 1-3/4 inches, and 2 inches. It also says it can be applied to LED light bars for “almost all types of vehicles,” which is broad—so you’ll still want to check your specific tube diameter and your light bar’s mounting pattern.
Also, note that the package list in the provided info mentions 4 mounting supports. At the same time, the product name calls it an 8-count pack. That mismatch doesn’t tell you the entire story, so before you commit, it’s worth double-checking what’s actually included in the box for your listing.


What you’ll notice in everyday use

The rubber inserts are the kind of feature you only really appreciate once you’ve got the bar mounted and you start driving. They’re meant to reduce vibration and help prevent the light bar from getting scratched by contact with the mounting surface. In real life, that means fewer annoying noises over rough terrain and less concern about cosmetic wear on the bar.
There’s also the “raised height” angle mentioned: the bracket setup is intended to elevate the light bar to help avoid scratches while driving. If you’ve ever mounted a bar too low and worried about it brushing surfaces, this is exactly the kind of design detail you’d want to see.
Installation experience (and the limits)
On paper, installation looks straightforward: pre-perforated holes plus an Allen hex key included. That combo is often what separates an easy afternoon install from a half-day of digging through tools and improvising.

That said, your end result will depend on your mounting location and how your roof rack or roll cage tube is oriented. If your tube setup doesn’t align well with the light bar’s mounting points, you may still need to spend time aligning everything before tightening.
Who it makes sense for


It suits you if you’re adding an off-road LED light bar to a roof rack or roll cage and you prefer clamp mounting over drilling. It’s especially compelling when you want a sturdy metal mount paired with vibration-damping rubber to protect the bar’s finish.
It may not be the best choice if you’re working with a tube diameter outside the stated ranges, or if your LED light bar’s mounting hardware doesn’t match the way this kit clamps and secures. In those cases, you could end up fighting fit issues instead of getting a clean, stable install.

Is it worth it?
Worth considering if you want a clamp-style mounting kit for an off-road LED light bar on roof rack or roll cage tubes, and you care about reducing vibration and protecting the bar from surface rub. The aluminum-alloy construction plus rubber inserts is the core of why this kit can feel solid over time.

Better avoided if your tube diameter isn’t one of the listed sizes, or if you can’t confirm that the included hardware quantity matches what you actually need for your light bar setup. And if you’re expecting a universal “works with everything” guarantee, keep your expectations grounded—this kind of kit still requires checking the compatibility between your tube, your bar, and the mounting points.
