In my old 2002 I don't recall any red light on the passenger side. But, if you mean on your control cluster check out your manual.
The blinking red light in the dashboard is an indicator that your anti-theft security system is armed and working.
Need to know which light is blinking.
If the check engine light is blinking on your 2005 Dodge Stratus, you most likely have a sensor that is damaged or requires replacement. You can check this by accessing the diagnostic computer at the dealership.

Low tire or sensor failure.
A flashing check engine light is an indication of an engine misfire.
Heater plug operation W/L
The factory alarm is armed
If you have factory alarm, you have a right light blinking in the dashboard (on the top of the light there is word "alarm") when the alarm is on. If you have aftermarket alarm, then the blinking light is usually to left of the steering wheel next to mirrors regulator.
