According to one embodiment there is provided a lamp device (1) having a lighting module (3) and two pairs of external connection pins (5aa, 5ab, 5ba, 5bb) for connecting the lamp device to a supply voltage of a lighting fixture. A first terminal of the lighting module is connected to a pin of a first pair of pins by a switch which is closed in response to a voltage difference between both the pins of the first pair of pins and the pins of the second pair of pins exceeding a respective threshold voltage. The lamp is therefore safe to handle even in a condition where one pair of pins is connected and the other is not. |
