Manufacturer Description

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness.

Replaced my 19 inch Nilight after 6 years. This 26 inch fits perfectly and is bright af. Outstanding product. Doesn’t come with wiring harness, but my existing one worked great. Looks awesome!

Brighter than my headlights on bright!
Color: 26Inch Light White
This Nilight 26 inch 540 watt 50,000 lumen Triple Row Driving light is the brightest light I've ever had on my truck. I bought a kit to mount the light to my Grill Guard, just above the bumper. I can see deer just like daytime, at least two blocks before I get to them. I've never seen a light bar as bright. There are no cons if you ignore the fact that it comes without a wiring harness. I definitely recommend this light bar!

Satisfied customer!
Color: 26Inch Light Amber&White w/Wiring Harness, Color: 26Inch Light Amber&White w/Wiring Harness
First, the picture isn't great, but I didn't intend it for the review. I'm really impressed with the quality and brightness of this light for the price! Installation was easy and straightforward. If you can do some basic work with hand tools, you can install this light in about 30 minutes, including wiring. I like the functionality of having the different light modes, although I typically just use the bright white setting. Some people complained about water getting into their light, but I haven't had any problem with water resistance after several months (including rain, snow, off-roading, and spraying it down with high pressure at the car wash. It fit perfect, just make sure you pay attention to the measurements before you order.

Great performance but low grade material.
Color: 26Inch light White +Wiring Harness, Color: 26Inch light White +Wiring Harness
I want to give it 5 stars but I can't because: The light bar is extremely bright and they go a great distance. I am very satisfied with how much it puts out. 5 out of 5 stars for its performance. HOWEVER nilight seems like they're starting to go cheap with their build material. 2 out of 5 stars for that. I have added photos of the older material vs new material for reference. Their old material is 3.3mm thickness compared to their new material at 2.7mm thickness. And that's for the mounting brackets and the light bar housing. It doesn't seem like .6mm would be a big deal but it's noticeably less rigid. Hand tight started bending the metal. Great product for sure but build material is low grade. Not trying to knock them, I love nilight products and will keep using them but it seems like they trying to save money by cutting weight which makes it less rigid. Dings and scratches come easily now. It worries me a little bit if it can take the abuse of vibrations over time from driving around now.

It will light up your life
Color: 26Inch Light White w/Wiring Harness
I only got to use them once before my jeep was totaled. They’re super bright. Great build quality. It survived taking a header down a mountain side and rolling 4 times. When the jeep was recovered, the light bar still worked!!
