Use of Left/Right in descriptions

[Magnus Forsberg]

Pattern descriptions on stickers are often in need of a Left/Right qualifier.
I think we are maybe using it very differently among the part authors.
I find it odd that I often feel I have to correct the descriptions on stickers intended for vehicles.

There is a definition of Up in the sticker specs.
"The sticker should be oriented such that the top of the pattern aligns with the +Z axis."
But how about Left and Right?

Imagine a vehicle with an arrow pattern on the right hand side pointing backwards.

The description should be "Sticker ...  with Arrow Left" but it should be placed on the right hand side of the vehicle.
How do I describe that pattern?   "Sticker ...  with Arrow Left Right"
On the opposite side it would become the opposite, "Sticker ...  with Arrow Right Left"

We have a qualifier (Formed) on formed sticker.
Maybe there needs to be a (Right) qualifier for stickers intended to be on the RHS (right hand side) of a vehicle?
And of course (Left) on the LHS.
