Do people really watch your license plate frame to see if there are amber lights? If I saw one light up amber, I wouldn't think anything of it, but if the 3rd brake lit up amber, I might think to ge off the gas. This idea seams to be looking less practical, IMO.

Anyway,  if I was to use an LED brake light flasher/strobe,   I would use this one.  It's only 15x15mm, so it could fit inside the lamp case, and handles up to 100W of bulbs or LEDs.  It's also fully-programmable, so you can control the initial strobe rate, the strobe duration, the total time of a cycle, and if it repeats, etc.

 

The only extra thing it needs is a momentary pushbutton for the programming stuff.

 

It's only $20.

I don't know, maybe we're overthinking this. If anything draws attention to your car by the driver behind & keeps their attention, you've got less of a chance of getting rear-ended.

I think that would be really bad.  I've had a couple close calls from people driving alongside me, with the driver looking at the car, and drifting into my lane!  Similarly, if you had something like a bumper sticker that was hard to read unless you were very close-  you know what would happen if you had to suddenly brake...

 

But I see your point- to have a warning device that is unmistakable. You want them to be aware there is a vehicle in front of them, but not to be obsessed so they stop paying attention to safe driving........
