Since more and more people prefer to add light bars on their vehicles, sometimes people will find that their new-purchased light bar cannot light up. What is happening to the light bars? Auxbeam as an LED manufacturer, here wants to tell you how this happens and how to fix it.
When you purchase a new light bar, you’d better try whether it can light up before installing it. You can directly connect the positive and negative pole of the light bar right to the battery of the vehicle. If the light bar cannot light up, you’d better check whether you have connected it in a right way. If everything is alright, but the light bar still cannot light up, maybe it is the light bar problem. But I suggest you can use another battery like checking the light bar on other vehicles’ battery or others batteries Pay attention: the battery needs to be about 12V-30V. If the light bar still cannot light up, which means the light bar is broken. You can just go to the store you purchase and ask for warranty.
If you connect to other battery, then the light bar comes up, that means there is something wrong with your battery. You need to check your battery. Some situations like the light bar can light up but some part of the LEDs cannot may also due to the low battery. In fact, the battery needs to be checked over time. A car battery is equipped with a storage battery. If you do not use the car, the car battery will discharge, then it cannot work. Also, some situations like starting the engine continuously will lead to the battery discharge excessively.
In fact, you had better keep a portable jump starter battery power in case your battery dies during the driving period.
