I've got the rear flasher on my road bike tucked as high under the seat as it can get, but even with a large frame bike and relaxed commuting (non-aero) posture I'm shorter than the hood lots of full-size SUVs and pickups, much less the seat.
I agree with the other commenter that a 360 cam on top of the helmet has been the most important thing for deterring tailgating and road rage. I've added reflective tape on the frame, the blinking blinking lights under the seat, a headlight on the handlebars and a headlamp with front white and rear red light, and my backpack has a nearly fluorescent neon green cover. Those all help reduce the "Oops, didn't see you there while looking at my phone" close calls, but do nothing to reduce intentional harassment - that's the function of the camera.
Sorry if I was unclear. I have two rear lights. The first one is mounted on the seat post near the eye level of sedans. The second one is mounted at the bottom of the helmet near the eye level of large SUVs.
