The DL-03SR is not a pure speedometer but a multifunctional cockpit and thus also the first KOSO round instrument which combines tachometer and speedometer as well as many other functions in one device. Below the display are 5 signal lights (turn signal, high beam, EOBD, oil, neutral). However, these are only visible if the corresponding signals are triggered. Instead of the tachometer, you can also play a volt and fuel gauge. If you are in speed mode and reach a critical fuel level, this will be indicated by a flashing icon. If your fuel gauge does not have one of the adjustable basic resistances of 100/250/510 or 1200 Ohm, you can also teach the fuel gauge in the learning mode for a correct reproduction. Due to a KBA number & ABE the DB-03S is registered in Germany.
