It looks like a 914 tach. Since the tach guts count ignition pulses, a 6-cylinder tach will read wrong on a 4-cylinder motor, and vice-versa.

As you have been told, the light next to the two triangles is the single turn signal indicator. It should blink when either the left or right turn signals are blinking. And the light next to the shining light symbol is the high-beam indicator.

The similar lamp on the speedometer is for the running lights--it should be on when the headlight switch is pulled partway out, turning on the running lights but not the headlights.
