* Parking lights: These are the smaller lights in the front bumper and/or headlights that are often left on as a low-level running light. They're not technically DRLs in the same sense as a dedicated system. To change these, you'd need to replace the bulbs themselves.
* Aftermarket modification: Someone may have added aftermarket DRLs. To change these, you'd need to locate the specific installation method used by the previous owner. This could involve anything from adding new bulbs to a more complex wiring harness.
To troubleshoot what you're seeing:
1. Identify the lights: Determine exactly which lights are illuminating when the car is running. Are they the parking lights, headlights at low intensity, or something else entirely?
2. Check the wiring: If it's an aftermarket system, tracing the wiring may be necessary to find the bulbs or LEDs.
3. Consult a wiring diagram: A wiring diagram specific to your 2001 Camaro would help determine the circuit used for any lighting system. You can often find these online through repair manuals or automotive forums.
Without knowing what type of lights you're referring to, it's impossible to give precise instructions. If you can provide more details (a photo would be helpful), I can give more tailored advice.
