YJINGRUI LED Industrial Signal Tower Light 3 Layers Flash LED Light with Buzzer Alarm Warning Lamp for CNC Machines (DC12V)

The YJINGRUI Industrial Signal Tower Light is a multilayer stack alarm warning lamp designed for CNC machines. The product, which operates on DC12V, is said to have a misleading picture as it only comes with three lights instead of the advertised five. Additionally, some customers reported that the product lacked any literature or instructions and did not come with a mounting plate at the bottom. On the positive side, the product was praised for its fast delivery from China. One customer mentioned that everything works as expected and even included a picture of the wiring diagram that came with the product. The wiring diagram showed a different configuration than the one in the picture, but this could be due to different wiring configurations for different stack sizes. The customer explained that connecting the thicker red wire to positive and the thicker black wire to ground would enable the pulsing light or buzzer function. Alternatively, connecting the light or buzzer directly to the black ground wire would provide a solid light or buzzer. Another customer noted that the product is made of plastic, including the base and mounting conduit, so caution is required to prevent breakage. However, overall, they were impressed with the product. It was mentioned that the LED lights are clear from a decent distance and the alarm is loud enough. The only drawback mentioned was that the cables are a little short, but this was manageable. Overall, the YJINGRUI Industrial Signal Tower Light receives mixed reviews. While some customers praised its functionality and fast delivery, others were disappointed by the misleading picture and lack of literature or instructions. The product's plastic Construction was mentioned as a potential point of concern, but the LED lights and alarm were commended for their visibility and sound.
