I just installed the Spec-D Sequential Tail Lights. I love the look, but have concerns about the behavior of the lights during braking. When applying the brakes, (1) the sequential animation turns on, (2) the sequential animation turns off, then (3) the Spec-D brake LEDs turn on. My concern is that this unusual behavior might cause drivers behind me to become confused and possibly hit me. Also, when releasing the brake when the lights are on, there is a delay before the running lights turn back on.
I'm interested to hear others' feedback. I've emailed Spec-D about possibly modifying the behavior of the light, but I've not received a response.
Here is a video that I took that shows all of the functions of the tail light:
