Based on the input for the guard rail idea, I'm gonna give up on putting
a strip on the guard rail.

As people said:
a) Cost too much to do it with permits
b) Risk too high of unintended consequences (e.g., blind other drivers)
c) It will get 'filthicated' at that low level
d) The town will remove it if they see it

So, I give up on the guardrail idea.

The only thing left (other than making a turnout) is the standard convex
mirror ...
