Why a Warning Light Is Actually Smart
Gauges require attention. A warning light demands it.
This is perfect for:
- Situations where you can’t constantly monitor gauges
- Critical thresholds like low oil pressure, high temp, overboost
- Track or racing environments where reaction time matters
Think of it as your engine’s way of yelling, “HEY… DO SOMETHING.”
