Solution 1: First, check whether the light bulb can't work normally due to the power supply. If so, check the power supply circuit. If the power supply is normal, the indicator light on the light bulb will light up.

Solution 2: In addition to eliminating the power supply, if it still doesn't light up, it is necessary to check the positive and negative pins of the light bulb to see if the operated light bulb is connected correctly during operation. If the bulb does not light up due to incorrect operation, it can generally be solved by re-welding the bulb.

Solution 3: Check the bulb current to see if the current at both ends of the bulb exceeds the working current of the bulb. If so, the light bulb may not light easily. The solution is to choose a suitable constant current power supply and try not to buy those cheap power supplies. This can prevent the bulb from not lighting because the power supply current is too large to break through the bulb.
