Two of the most commonly confused vehicle dashboard tell-tales — both relate to braking, but signal very different levels of urgency.
Go by colour. The red brake-system light can mean a serious hydraulic fault affecting your ability to stop, and warrants stopping safely and checking. The amber ABS light usually means only the anti-lock function is affected, with ordinary braking still working — but get it checked, because you have lost skid protection.
Both belong to the Vehicle dashboard warning symbols system.
Drawn from the visual attributes recorded for each symbol. Only traits the two records disagree about are listed.

| What it warns about | Parking brake engaged, or a low-fluid/hydraulic fault | A fault in the anti-lock braking system specifically |
| Does normal braking still work? | Not necessarily — this can indicate a serious hydraulic fault | Usually yes — only the anti-lock/skid-prevention function is affected |
