Rear center bumper tail/brake light for Prius C?

I think my 14 C can use much brighter tail light, I replaced the 194 bulbs w/ LED bulbs but still lacking in brightness.

Then, I saw these triangular hyper bight third tail lights on a Mini and a RSX... These lights were hyper bright, almost like a brake light bright. When braking, it also blinks... very cool and BRIGHT! Lights were of bright red LEDs staked in an inverse triangle shape. Mini looked almost stock.

Anyone have this installed and know where we can get one?

thanks!
