Safety lights are an important feature available in almost every car. Located on the dashboard, these lights blink upon detecting a potential problem in the vehicle that needs the driver’s attention. While some issues can be resolved immediately with little technical knowledge, others require a mechanic’s intervention. Individuals who have bought their first car and are learning to drive should know what these lights are for so they can take necessary action when needed.
Oil Pressure Warning Light
The oil pressure dashboard light’s function is to inform the driver when the engine oil pressure has decreased. Lower oil levels can harm the engine and accelerate the internal breakdown of its components. When this light comes on, one should check the oil level and refill it as needed. One should always use an engine oil grade that the vehicle manufacturer recommends. If the oil pressure indicator remains on, it could sometimes indicate a more serious problem, such as a broken oil pump that requires intervention or a leak on the tray that needs sealing.
Coolant Check Light
Coolant is a special liquid that circulates in the engine to keep it from getting too hot. When the coolant check light illuminates on the dashboard, it is a serious matter of concern. This warning light may indicate the engine is overheating, potentially due to a lower coolant level. It could point toward a faulty thermostat, a damaged radiator, or internal engine problems. An overheating engine could cause permanent damage to the vehicle. If the light turns on, one should pull aside and immediately turn off the engine so that it cools down. Once the engine has rested, one can check the coolant level and top it up. If the car continues to overheat, one should have it towed to a garage for a professional inspection and resolution.
Check Engine Light
The check engine light is another important car dashboard signal that indicates a potential problem. It may turn on for several reasons, including issues with the catalytic converter, spark plugs, gas cap, or faulty sensors. The extent of the damage depends on whether the warning sign is lit or flashing.
- A lit check engine light means there’s still time to get it checked. While the car can continue the journey, a mechanic must inspect it as soon as possible.
- A flashing light indicates a misfiring engine and requires pulling over to get the car towed before it worsens.
One of the most effective car engine troubleshooting tips during such a situation is to use an OBD-II scan tool to identify the issue. Alternatively, a professional can conduct a test to determine the cause of the check engine light and resolve the issue.
Brake Light
A vehicle’s brakes help slow down and stop the car, making it a vital component. If the brake light turns on, it’s best to pull over and stop the car. This vehicle alert could mean several things. For instance, the brake system could be malfunctioning or the parking brake might be engaged. Other reasons include low or leaking brake fluid, faulty sensors, worn-out brake pads, or a jammed parking brake. One should not take any chances with this car safety indicator. It’s advisable to have the car serviced by a professional immediately to diagnose and fix the problem.
Airbag Warning Light
Airbags are a vital safety feature that creates a soft cushion during a collision, protecting the driver and passengers. The airbag warning light, also known as the SRS light, may turn on if there’s a fault with the airbag sensor, a minor collision, or a seatbelt issue. If this light is on, it means the vehicle’s safety feature is disabled, and the airbags won’t deploy until the problem is identified and resolved. One can use an SRS OBD2 scanner to identify the fault or seek expert intervention.
Tire Pressure Warning Light
This light indicates issues with the tire, such as under-inflation. Lower tire pressure may reduce fuel economy and cause the tires to wear out. It could also trigger tire failures, which is a serious safety concern. Reduced temperature and small punctures are common causes of tire pressure loss. If the car does not have an inbuilt monitoring system, one can use a gauge to check the air pressure in all tires. The light should go off after bringing them up to optimal levels (or fixing them in case of a puncture).
Battery Warning Light
This indicator lights up when the car’s battery isn’t charging. While the car may run for a short distance on the remaining charge, the battery will eventually cease to work, causing the vehicle to stop. This usually happens when the battery is old or corroded or has damaged cells that need replacement. It could also be a sign of a faulty alternator. Either way, having the car checked by an expert and fixing the battery is essential.
Lamp Out Light
Most cars have an illuminated bulb-like icon, with an exclamation mark in between, that turns on if the headlight or taillight bulb fuses. Whether during the day or night, one should replace the bulb as soon as possible to ensure maximum visibility on the road. Headlights and taillights are also important because they alert drivers at the front and rear.
