Santa Fe (DM - 2013+) :: Flashing Third Brake Light

It was discovered last night that the third brake light (or Center High Mounted Stop Lamp/CHMSL) on our SF flashes a few times before going solid when I brake. I did a little searching and it seems that it is not legal in TX, so I guess I get to put in a call to the dealer today.

From what the interwebs say, it seems to be something dealers do as an added "safety feature" (and I even found research that shows it does get attention better than solid lights). There's a lot out there about people wanting to install this feature, and there are companies that do this for you. But I've never seen it on the road myself, and to be honest, it's kind of annoying. And the TX code is not the clearest, but I think it's saying "no flashing lights unless you're a bus."

Here's what I found from the TX transportation code:

(c) A person may not operate a motor vehicle equipped with a red, white, or blue beacon, flashing, or alternating light unless the equipment is:
(1) used as specifically authorized by this chapter; or
(2) a running lamp, headlamp, taillamp, backup lamp, or turn signal lamp that is used as authorized by law.
(d) A vehicle may be equipped with alternately flashing lighting equipment described by Section 547.701 or 547.702 only if the vehicle is:
(1) a school bus;
(2) an authorized emergency vehicle;
(3) a church bus that has the words "church bus" printed on the front and rear of the bus so as to be clearly discernible to other vehicle operators;
(4) a tow truck while under the direction of a law enforcement officer at the scene of an accident or while hooking up to a disabled vehicle on a roadway; or
(5) a tow truck with a mounted light bar which has turn signals and stop lamps in addition to those required by Sections 547.322, 547.323, and 547.324, Transportation Code.
