It's a good one, buy it.
Size: 16 AWG-100 ft
Actual 5 stars! OFC, copper stranded wire, takes solder nicely when tinned, stiff and pliable enough to stay bent. covering melts INTO wire as expected. I was hoping for a good deal and got one.

Not bad for money. But the spot lens is def a narrow spot
Color: 4.5inch Spot Light, Color: 4.5inch Spot Light
I did a direct comparison to BD squadron pro with spot lens. Pic one is 1 squadron spot lens, pic two is 1 auxbeam 4.5 Not a pair. Only one light each. Then the video is 2 squadron pro one with spot lenses the other with combo lens. Then both auxbeam 4.5. I wouldn’t buy the spot lens unless you have other lights or just trying to light a narrow beam a long ways. The fill light is not good. I say the brackets and the finish is on par with BD, not as deep as the XL80 but similar in size. The BD XL pro is def brighter with better fill even with spot lenses. I would say 4 of these would match the XL Pro at half the money if you have the space for four of them. But even 4 don’t match the XL80’s. But for 160 bucks it’s a good solid light.

Great quality, and very bright.
Color: 4inch Spot Light, Color: 4inch Spot Light
I installed 4 of these pod lights in the front bumper of my 2009 f150 (2 spot beam, and 2 combo beam), and I am very pleased with the overall build quality, and brightness of these pod lights. Installing them is fairly straight forward once you have them mounted where you want them, and they look great! I highly recommend these lights if you are looking to upgrade the lighting on your vehicle! The video I have attached is with the amber lens, and the picture with the lights on is without the lens. I prefer to keep the lenses on most of the time since it does add a layer of protection from the sun, and bugs/rocks while driving. I also do prefer the amber color for driving at night compared to the white.
