Review on 🚀 OZ-USA 1 Pair Mini Trail Lights: Powerful LED CREE Spotlights for Offroad Motorcycles and Dual Sport Bikes by Danny Rogers

First impression I installed it on my KTM 1190 Adv R. WOW! I can't say enough is enough. These things are very bright for their size. YUGE hits the dollar here. Very white, light. Great spots. Highly recommended. Impression after > 1 year: Inexpensive in the truest sense of the word. That's why I don't mind buying them three times already. My First Purchase: First impressions were that they are amazing. After a few weeks, one of the original pairs began to dim and eventually went out. I bought a new set. Second sentence: They probably lasted about a year. I had trouble tightening the screw that attaches the light body to the bracket. This is an M3 screw with a 2.5mm hex socket. Tried Locktite - did not help. The light vibrates and finally the bolt fires. After some time on the road, the vibration began to destroy the wedge-shaped aluminum bracket - both surfaces, the fixed bracket and the lantern body, until the lantern fell off completely on one side. The through channel through which the shutter passes was completely worn out, there was also no wedge mechanism. All this through vibration. I even undercut the screw by 2mm and used Locktite 271. Third Purchase: They're cheap and bright. So I bought a third set. This time I coated the aluminum base wedge and mating surfaces of the RTV body and the RTV secured the bolt in place. The RTV should also hold up to vibration (I tried this on a previous headlight that didn't fail completely and it still holds up, albeit badly worn but not frayed through. The RTV held it in place). However, in less than a week, the brightness of one of the new lights dropped to less than 50%. I disassembled it. The self-heating LED and one of the regulator's inductors burned out to a dark brown color. One part was so hot it broke off the circuit board. I removed the circuit board from the case. The thermal grease was applied, but less than 50% of the grease was actually in contact with the PCB (aluminum backed board) due to the flatness (or lack thereof) of the case's contact surface. The housing is cast, the surface of the cooler is not polished. This is necessary to ensure reliable and stable quality of the device. As an electrical engineer with 20 years of experience in the power electronics industry, I therefore point out TWO design flaws and a complete lack of quality control. Two design flaws: The case's heatsink surface is not machined to standard heatsink flatness tolerances, leading to part variation and thermal failure. Second, the lack of vibration resistance. The problem with quality control is obvious - two of my six lights failed due to temperature issues. These problems should have been discovered during product testing. But I think if the product is cheap enough, people will buy it. If "enough" of these work, people will keep buying it. Product quality and price are clearly in line with market demand, and volumes are high enough to keep production profitable. Attention buyers.
