  • Lot's of light, more flood than spot style
Size: 20 inch
Didn't seem to be a good wiring diagram and you will want to use a relay (not included). I was replacing a different 20" bar so already had wiring in place. Not all 20" bars are the same size, and this was about 2" bigger than my last one, so had to drill some new holes. Casts very tall light vertically. Ok for width. Obviously used off road or to light up area and works well for that. Hopefully last longer than my previous one that must have not been well sealed. ... show more

  • Good light. Very bright
Size: 20 inch
Awesome light for the price. Seems like good quality but time will tell. Definitely brighter than the 20" dual row I had on there before. So happy with the 20" I decided to order a 54". ***just an update. Almost 4 years later and I still have both these lights on my truck. Both of them still working just as good as the day I bought them. Only thing worth noting is minor sun fading of the paint because the truck sits outside 24/7 down south but other than that no moisture intrusion or any LED’s out. One of my best purchases. ... show more

  • Hardware
Size: 50 inch Curved
Wrong hardware. Cooling fins bent up and there was no damage done to box so it had to have been packaged with damage. The wiring harness that it comes with is short on the wires that go to the switch from the battery terminals, had to cut and splice in longer wires. Light bar is super bright tho. Seller was very urgent in fixing these issues tho and assured me it was a mistake in packaging the item. Made it right with refund. ... show more

  • Hardware does not fit!
Size: 40 inch
The media could not be loaded. This is my second lightbar! First one the hardware did not fit on one side of the bar only the other side got fine! I thought it was a fluke so I ordered a second one and was going to return the first one but the second one also the bolts did not fit just the one side! This is crazy! I have no time before my trip to try this a 3rd time or order from another company! I’m so frustrated! ... show more

  • no mounting ability for most applications.
Size: 30 inch
Unless you have a steel bumper, there is no way to attach the unit to the car/truck. Most bumpers are now plastic with an inner steel bumper not reachable without taking off the plastic bumper...a huge undertaking, even for a gear head like me. No less than 24 fasteners and bolts hold it on. Then, you need to be a fabricator to build an extension from the inner steel bumper to reach out to the front of the vehicle. This is not a job for a casual do it your selfer. Torches were required, drilling and wrenching. Instructions are non existent. However...once mounted and wired, the light bar performs excellently. Light bars are especially useful in areas without street lights...very easy to out run your typical headlight on a dark highway. I use this exclusively in Mexico...not sure if it's legal in U.S. ... show more
