In the world of Jeeps, commercial trucking, classic cars, and motorcycles, the LED headlight has become a hot topic. My name is Chris with Headlight Revolution, and in this review we are digging into the Nolden GL-180 LED headlights, one of the more interesting 7-inch round options on the market today. We tested this headlight in our stand at 25 feet from the wall so we could measure Lux, study the beam pattern, and compare it fairly against the newer competitors. If you want an honest look at what this light does well and where it leaves a little to be desired, keep reading.
Who Actually Makes the Nolden GL-180?
This headlight is most commonly known by its Nolden branding, and it has an interesting history. For a long time in the German truck aftermarket, this was a highly sought after headlight, but until very recently you could not even get it in the States. Once it was discovered that a company out of Taiwan called Giant Light was actually the one manufacturing it for the German company, it all of a sudden became super available. Now you can get it in a chrome version or a black version, and you can buy it from Nolden, directly from Giant Light, from Recon, or from United Pacific. No matter which brand you buy, it is the same headlight built the same way.
The GL logo on the front stands for Giant Light. If you flip the headlight over and look at the back, there is an embossing on the aluminum heatsink that reads NCC E GL-180. That is the Nolden brand carrying the Giant Light 180 part number. Whether you get it from Giant Light, Nolden, United Pacific, or anybody else, it is going to carry that same information, and down at the bottom it actually says Made in Taiwan.
How the Nolden GL-180 Beam System Works
The way this headlight operates is genuinely cool, and it obviously has a really nice look to it. On low beam, you have the center projector and the top projector turned on. That combination is what creates your cutoff line and the left-to-right spread, along with a little hot spot right in the middle. It is a smart use of two light sources to build a proper low beam pattern with a defined cutoff.
When you switch to high beam, a lot changes. The center projector actually turns off, and now the lower reflector bowl lights up while the upper projector stays on. That is what produces the distinctive five round circle configuration you see on the wall, plus the arcs that fill in the gap above the low beam cutoff line. It is a different approach than most 7-inch round LED headlights use, and it is one of the reasons this light stands out.
Details We Noticed During Testing
One of the details we appreciate is that this housing is marked DOT and SAE, so it is legal to use on American streets. That said, keep the regional supply chains in mind. If you want to use it in America, do not buy it from Germany, find an American supplier. If you are in Europe, find a European supplier. The product is the same, but sourcing it from the correct region keeps everything above board.
Something really interesting about this headlight that we do not see in many modern designs is the presence of two great big moisture vents. Most of the 7-inch round LED headlights we test either do not have them or use much smaller ones. These are large and clearly visible. If you are shopping across the broader market, take a look at our universal sealed beam LED headlight collection to see how different manufacturers handle housing design and sealing.
Mounting Depth and Fitment Warning
This is an important one. The Nolden GL-180 is not going to fit in a Jeep Wrangler. It is simply too tall, and it has a mounting depth of over four inches. In fact, the measured mounting depth is 4.45 inches, which is a huge amount of depth compared to many competing 7-inch round headlights. If you are a Jeep owner reading this hoping to run these, this is your heads up that they will not clear.
For applications where depth is not a problem, that is fine, but for Jeep Wrangler owners specifically, you will want to look at something shallower. If you need a Jeep-friendly option, consider the Holley RetroBright 7-inch round sealed beam LED or the Vision X VX Series 7-inch round LED headlight, both of which we have tested in the same 7-inch round format.
Electrical Specs
The United Pacific / Nolden / Recon part number 31300 uses five Osram LED chips and accepts a 9-32 volt DC input, which makes it flexible across 12-volt and 24-volt systems. It draws a modest 1.4 amps on low beam and 1.4 amps on high beam, so power consumption is very reasonable. That combination of wide voltage range and low current draw is part of why this design remained popular in the commercial and truck markets for so long.
Low Beam Beam Pattern and Lux Results
On low beam at 25 feet, this headlight measured 429 Lux, and the beam pattern is really nice. It has a slightly bluish white hue, and the spread is huge. We could not even see the whole thing at 25 feet because it goes off the edges of our wall. It has a defined cutoff line with that up and to the right dip, though it does not project quite as far down the road as a true projector headlight would. Keep in mind this is a slightly older model design.
Looking at the low beam more closely, the light does dissipate fairly sharply at the edges, so it is not nearly as bright out there as it is in the center. In terms of raw and effective output, the low beam is rated at 1880 raw lumens and 1550 effective lumens. On the road, you get a nice cutoff line in the ditch, a step in the center of the pattern to shield oncoming drivers, and a centered hot spot with a decent left-to-right flood. The beam pattern extends nicely into the ditch even if the downrange reach is not the longest we have measured.
High Beam Beam Pattern and Lux Results
When we switch to high beam, a lot changes. The center projector shuts off, the lower reflector bowl kicks on, and the upper projector stays lit. That creates the five distinct round hotspots in the center of the pattern, along with arcs that start in the middle and extend out to each side to fill in the gap above the low beam cutoff line. Those five distinguished circle hotspots are your long range, down-the-road lights, and further out they tend to mold together into more of a single round circle.
That extra light is significant. High beam jumps from 429 Lux on low beam all the way up to 981 max Lux at 25 feet, with a raw lumen rating of 2400 and an effective lumen rating of 1700. What is genuinely unique here is that on high beam you can still see a bit of a cutoff line on the left and right sides in the ditch. Most of the time, when you go from low beam to high beam with other headlights, nothing is controlled in terms of height, and the light just opens up completely and shines as much as it possibly can. The Nolden keeps some vertical control while still throwing a lot of light straight down the road.
How It Compares to Other 7-Inch Round Options
This LED headlight, originally marketed by Nolden and now available from several other brands, is a pretty decent competitor in terms of beam pattern and brightness. The controlled high beam is a real differentiator. That said, the deep mounting depth rules out a lot of vehicles, and the low beam does not reach as far downrange as some newer designs.
If you are cross-shopping, a couple of strong alternatives worth looking at are the Morimoto Sealed7 2.0 universal bi-LED headlight and the broader TRS universal LED headlight assembly lineup. Both give you modern bi-LED performance in the 7-inch round format.

Our Take
We are not going to rank these best to worst, because the right choice depends heavily on your vehicle and how you drive. What we will say is that the Nolden GL-180 has a cool look, a genuinely nice low beam pattern, and a high beam that keeps more height control than almost anything else in the category. The main drawbacks are the deep mounting depth (which eliminates Jeep Wrangler owners) and a low beam that leaves a little to be desired at the edges and downrange. If those tradeoffs work for your build, this is a solid, DOT and SAE legal choice with an interesting history and a proven track record in the truck world.
