[History]

Being very rural I'd probably use what came on the car or add signals. I drove a truck and I've worked where the traffic had to be controlled and one thing you can count on is that you CANT count on people to be aware of their situational position. I was standing with a stop sign in my hand with a state trooper beside me with maybe ten vehicles stopped. Here comes a car around everyone and keeps going until my friend (state trooper) turned on lights he couldn't miss. Some people are stupid and some, I have no idea about but people don't see things the way most of us do. Motorcycles get hit by other vehicles because people's brains don't accept them being there, vs hitting an eighteen wheeler, their brain accepts that. It's not that your idea is stupid and without seeing it myself it might work but I'd not chance it. With an original tail light that is dim already the light could very well confuse a young person or person we all know.
