* Security Light on the Instrument Panel: Most likely, there's a small light (often an LED) on your dashboard, usually near other indicator lights. This light will typically blink slowly when the alarm system is armed and will remain illuminated, or flash rapidly, if the alarm has been triggered or there's a problem with the system. The exact location and appearance of this light vary depending on whether your Regal has the factory-installed security system or an aftermarket one. Consult your owner's manual for the precise location and meaning of any lights on your instrument panel.
* No Visible Light (Factory System): Some Buick Regal models from 1999 might have a factory security system that doesn't use a dedicated light on the dash. The system's status would be indicated only by the horn or lights flashing during an alarm trigger.
* Aftermarket Systems: If you have an aftermarket security system installed, the indicator light will be in a location determined by the installer. Check the system's manual for its location and meaning.
To find your security light (if it exists):
1. Consult your owner's manual: This is the best resource to identify the location and behavior of any security-related indicator lights.
2. Examine your instrument panel carefully: Look for a small light, often near other warning lights, that might have a key, lock, or similar symbol associated with it.
3. Test the system: Arm the alarm and see if any light on the dash changes its behavior (e.g., blinking or staying lit).
If you can't find any indication of a security light and suspect a problem with your security system, it's best to consult a qualified mechanic or a car security specialist.
