* Older Vehicles: Cars from that era generally relied on a more basic warning system. If your battery was low, a "Battery" or "Charging System" warning light would illuminate on the dashboard, indicating a problem, which could include leaving your lights on.
* Sounding Alarm: Some older vehicles might have a buzzer or chime that would sound when you left the headlights on after turning off the ignition.
* Modern Feature: The feature of a dedicated "Headlights On" indicator light is more common in newer vehicles for increased driver awareness and safety.
To be absolutely sure, check your 2003 CRV owner's manual. It will detail any specific warning systems for leaving your headlights on.
Here are some other ways to help prevent leaving your lights on:
* Develop a Habit: Get in the habit of always checking your lights after you park your car and shut off the ignition.
* Visual Check: Before you lock your car, do a quick visual scan to ensure your headlights are off.
* Keyless Entry: If your car has keyless entry, the headlights might automatically shut off after a set period.
