I did check out the regs. with the Federal agency - NHTSA. Not a problem. FL, well who knows :crazy:I know this may be a PIA, but before installing blinking tail lights or 3rd brake lights you need to check with your states vehicle codes on this. My motorcycle came with such a feature that makes the rear turn signals blink about 3-4 times when brakes are applied and was DOT approved at the time of manufacture and, I have had no problems with law enforcement. But, I have been told that some states do not allow such modifications. Just a heads up. Rather be safe, do some research before buying an item you can't use legally.
It could also be simply the frame rate at which the video was shot showing the LED light(s) flashing when in fact they are not....not to the eye anyway.
I looked up the brake light function in the owner's manual and you are correct. When ABS is activated in the BMW a second set of lights come at rear of the car and they do not blink.They do not. Blinking lamps on the rear of any vehicle are illegal in most states. There is no way BMW can sell a car that does that.
Howerver, every car sold in the states has blinking lights on the rear. Turn signalsBlinking lamps on the rear of any vehicle are illegal in most states
Bringing back this older thread.Just went thru this process... Also have the "Back-Off" brake light module on my HD Sportster and wanted to install on my 2007 Cayman. Dealer advised against it. The module will give you a warning message when brakes applied and also void your warranty (electrical).
