Some offerings are a long invisible strip stuck onto the back of wherever you want to stick it.
The box warns that metallic parts may interfere which put me off but
the center bit being behind the small area of a licence plate seemed to make no difference to it.
I found it was sensitive to relative movement rather than "closeness".
Good and cheap.
"Beeper reverse" was on the box. Made in China..but then so are some other bits of a 370Z. which also has USA and Czech Republic bits too!
