🔧 Pro Tip

The 72-tooth ratchet is a game-changer when working in confined engine bays or tight under-dash areas. Utilize the deep sockets with a small extension for reaching bolts on suspension components or spark plugs, while the standard sockets are perfect for everyday fastening tasks. Always ensure your blow mold case is properly latched to keep your extensive collection organized and secure.

Too big for a tiger, but works well on the fiddy
Color: 4*2.5in Cube LED Pod
Not as bright as the graph says they are, or maybe I'm not in a dark enough area at night. But they definitely are blinding. Were too big for my adv bike unfortunately, but they work good on my truck as ditch lights. Not too bulky looking like the cubes are and no wind noise that I can hear. Definitely lights up the wma trails and the side shooters are very helpful. I will note though that as soon as your hood gets dusty it becomes blinding from the inside side shooters though. so I painted the yellow lens cover on the inside sides and it helps a lot with the hood glare.

Easy Install Onto Jeep JKU, No Switch Backlight or Mounting Holes, Great Customer Service
Color: 5in Cube LED Pod, Color: 5in Cube LED Pod
I installed the Auxbeam 5" 168W LED Cube Pods onto my Jeep JKU Anniversary Steel Bumper. It was an easy install with some YouTube videos to help me snake the cables into the cab. The unused holes in the steel bumper were the perfect size to fit the mounting bolts on the pod lights, and there was plenty of room to reach under the top edge of the bumper to install the nuts with some Loctite. To snake the provided cable through the firewall, I had to remove the installed socket. This was easy to do by simply recessing the retainer clip on each pin, taking a picture of the wired connector before releasing the wires so I knew how to reassemble, snaking the connectorless cable through the firewall into the cab where the pins were then reinserted and locked into the connector. I dressed the cable by zip tie to the existing wire harness at the top of the engine bay. In the cab, I pulled the side panel from the dash (driver's side) and made a small hole for the cable in the panel. After cleaning the dash with alcohol, the adhesive-backed switch seems to hold nicely in place. The lights were very bright and did a great job of illuminating the front and sides of the trail ahead of me. No backlight on the switch, which is a necessity, and I dont understand why that feature is not present. Also, there is no through hole to mount as the adhesive back won't stay attached, so the lack of a mounting hole is a big negative as well. 5 Month UPDATE: One of the lights got water inside. I noticed two screws that hold the glass cover were loose on the bottom of both sides. The other light also had the same loose screws but no water under the glass. I contacted Auxbeam, and they replaced the entire set in 2 days. Very awesome customer service.

Brightness and quality
Color: 4*2.5in Cube LED Pod
Got this for my 2024 Crosstrek. Got this one specifically due to its functionality that I wanted, quality for the price and it looks great especially DRL. I leave the Amber cover on most of the time. If you want the DRL to be on while the car is on, you can do that but it has to be rewired which I did. Love the brightness. I’ve been having this on my Crosstrek for a few months now and have no issues.
