So I have noticed over the years that my security light at night blinks (obviously) and it is usually a slow blink. Sometimes it blinks rapidly. I have a blue security light in my 2010 sxt. I am not sure of the exact system as I bought the car used but they said there wasn't any after market parts in the car... recently we have had alot of thefts, breakins, ect in my area. Multiples a night! I am wondering if the l if the light blinking fast means someone tried to pull on a door handle? If you pull 3 times on handles when my car is locked the alarm will set off, it is also sensitive to people shoving the car ect. Does anyone think it is possible that someone was doing a door check? Sorry I don’t know more I have just always been curious and figured you guys on this forum could totally help!
