If the current is caused by a short circuit or an increase in current, please check the wiring.

Anonymous users2024-01-23The bulb is generally connected in series, so once there is a problem with the line, the bulb is not broken, all of them are not lit, and when you check it, you will know what is wrong with a multimeter!

Probably because of the moisture, the waterproof is not good, and the contact points of the bulb will oxidize and rust quickly, so the life of the bulb is short.

It's all right. There are two main functions of mirror front lights, one is lighting, and the other is to increase aesthetics. It depends on your needs. If you just want to illuminate the function. It can be installed directly on the integrated ceiling, and if you want to be beautiful, you should add one to the mirror.
Are you mentally retarded? Energy-saving lamps work on ballasts, and of course the ballasts have to be replaced. Of course, if you install a digital sectionalizer, it won't light up. Digital sectionalizers are not ballasts. The ballast is broken, and the ballast needs to be replaced.
LED lights with direct current, and positive and negative plate properties must be divided, you use 40KHz AC to connect the lamp I think is wrong, to use a high-frequency diode to rectify the filter and then connect the lamp.
