How do you connect the headlight?
The essence of the ballast fluorescent lamp is an inductance coil, so it is part of the positive and the negative poles of two lines to string into the circuit, you only need to get the red wall through the FireWire switch, then the ballast, and finally back to the zero line is not charged on it.What you said should be excluded, the first to determine whether the new lamp rated voltage is matched with the home power supply, whether the lamp is in good condition, and whether it has been verified at the time of purchase, whether it is an AC 220V.Second, if the lamp and rated voltage are no problem, then the two lines on the wall is nominal voltage, whether it matches the rated voltage of the lamp, it is best to measure with a multimeter, such as whether it is AC 220V.If the above two are no problem, but not bright, you can also select a power point test, whether it can light, and if so, that the original power supply may be zero line impassability.
Connect the bulb with a light bulb on the wall, and see the circuit on the wall is blocked.One must be bad for the two
1, you must make sure that the lamp itself is good.The method is that the headlight ballast is out, and the two red lines are respectively connected with the two sockets of the home socket. See if it's bright.
