How to troubleshoot solar led street lights if they fail

How to troubleshoot solar led street lights if they fail If it is suddenly not bright or dark, but other circuits are intact, that is to say, other electrical appliances are fine. In this case, the lamp is usually its own nerve, that is, broken. This situation is very common.

Let's take down the lamp first and analyze it slowly! Taking a simple LED bulb as an example, first open the cover and select the blade along the edge gap. After turning it on, see what drives the light.
