To build a lighting in a model, I searched for appropriate modules. Finished products could not satisfy me, because always some flaw was present (eg. Stoplight when reversing). Graupner has already proved by HOTT good cooperation with SJ and cost around 20 different lighting sets also the mounted diodes usually are cheap, sometimes completely unsuitable. Then there is the small size of the board, which is of Carson 4x the size! A little unusual for followers of the metric system, the circuit than minus! The four lines of the negative pole are passed via the consumer to the positive pole of the power source. The functions are (two channels) connected via a proportional channel, what is provided also, programmable Funke, a / can realize on / off switch or button 2 a. Operation switches depending on the state on or off, the duration of the operation (short or almost 1sec) one or the other function. Example: switch upward briefly = channel one, long up = channel two, short down ... Got used to it quickly. Jumper the function is defined, moment, on / off, two can blink with 1Hz (one sec.), The other two with 0.5Hz (2 Sec.). The board is enough to light a model car and / or equipped with additional functions. The cables are of high quality with silicone insulated, only during installation you should make sure to have among the jumpers not's conductive. Although the solder joints are also isolated, but I would not trust this thin layer (rubber or silicone?). But I believe this is no disadvantage, because I believe that a board should always be installed so that no short circuit can occur. So there is me full credit. A recommended product, which reliably does its job, this is pretty small and can be quite easily operated. Bravo Graupner / SJ
