20080224708 | Method and a Device for Detecting Signal Lamps in a Vehicle - Provided are a device and a method of detecting signal lamps in a vehicle, in particular in a large vehicle, being provided with a plurality of signal lamps each being capable of switching between an OFF-phase and an ON-phase. The method includes the steps of during the OFF-phase of a vehicle signal lamp to be probed inducing a probing current by connecting an electric current generator to said vehicle signal lamp circuit, where the probing current is lower than the nominal current for the lamp in question. The next step is to detect the electric voltage level over the lamp circuit and determining vehicle signal lamp characteristics such as type and condition based on said electric voltage level detection. The result of the determination is that the signal lamp is a LED lamp being connected, when the detected voltage level is within a predetermined interval between a first voltage level and a second voltage level. | 09-18-2008 |
