PROBLEM TO BE SOLVED: To provide a vehicular indicator capable of being shared among a plurality of vehicle types each having different memory configurations.SOLUTION: A circuit board 3 is provided with wiring and foot patterns for mounting a nonvolatile memory 4 to be discussed, a volatile memory 5 and control means (controller) 6. The circuit board 3 is provided with volatile memory foot patterns 5a, 5b, 5c, 5d, and maximum four memories can selectively be mounted. When two volatile memories 5 are mounted, for example, the volatile memories 5 are mounted on the foot patterns closer to the control means 6 in this order, that is, on the volatile memory foot patterns 5a, 5b. Resistors are mounted on resistor foot patterns that are electrically connected to the volatile memory 5 and closest to the control means 6. That means, the resistors are mounted respectively on resistor foot patterns DR1a, DR1b, corresponding to the volatile memory foot patterns 5a, 5b. Since the two volatile memories 5 are mounted, a termination resistor TR1b is mounted corresponding to the number of mounting two.
