Does the new Volvo S80 have a flashing rear windshield brake light?

I saw an S80 where the third brake light - the bar in the rear windshield - flashed like a warning every time the driver hit the brakes. Is this an add-on or something new for Volvo? I have a 1999 S80 and am interested in adding this safety feature to my car. Thanks!|||No this is not factory installed. To my knowledge some car companies (mercedes) are starting to look at putting a feature in to strobe the brake lights in emergency braking maneuvers, but this is not the norm. Especially if the brake light flashes every time the vehicle brakes, then this would defeat the purpose of alerting people to an emergency stop or a driver attempting an emergency braking maneuver. I've included a link below of a sample brake light flasher add-on. Lexus also has something similar to the mercedes, but it acts more so in an offensive sense and not a defensive sense. On their european models of the LS 600h they have a rear millimeter wave radar that monitors traffic behind you and if a person is coming up too fast when you are slowing or stopped, it will flash your brake lights at them as a precautionary measure. If you would like to add this feature onto your car, look into a third party market as your volvo dealer will not do this for you for liability reasons. Volvo does have something called crash warning with brake assist, where if you are about to rear-end someone it will flash a simulated brake light on your windshield to alert you to them stopping. Let me know if you need any more assistance or have any more questions about this or other automotive safety issues.|||Well it could be a possibility seeing as how the new s80 has many new groundbreaking safety features (it is a Volvo after all); but i haven't read anything about it,what i do know though, is that you can get and aftermarket part that will let you do just that. I'm actually considering buying one for an 89 Volvo 240 I'm gonna be buying soon. iv seen afew different ones for sale online, just type in something to the effect of "flashing third brake lamp" and you should get some results, if not just play around with similar words. |||Yes / No it's an option chosen by the factory. My neighbors flashing rear brake light goes right along with the rhythm of her wiggly 4 cylinder that did not come with motor mounts - just two cans of cranberry sauce on each side of the engine :(
