Morphology

traffic + light

The dashboard sense is directly derived from the literal device 'traffic light' (a light that controls traffic) and the widely shared color-coding convention (green/yellow/red = go/warn/stop). A B1 learner who knows 'traffic' and 'light' can readily infer the metaphorical use as a color-coded indicator by analogy to the road signal, so the expression is compositionally transparent.

Etymology

The noun traffic light comes from a simple street picture: a lamp with three colored lights that tells drivers and people when to 'stop', 'go', or 'slow down'. That's why the phrase means the device at crossings that controls movement.
