I'm using a tikzset command to set a global style
\tikzset{FARROW/.tip={Latex[angle=40:2.5mm]},
FARROW/.style={line width=3mm}
}
When I use it for an arrow, the arrow head style conforms to the style, but the line width stays the same
\begin{tikzpicture}
\coordinate (o) at (0,0);
\coordinate (e) at (0,3);
\coordinate (ball) at (0,3.05);
\coordinate (i1) at (2,0.5);
\coordinate (i2) at (2,2.5);
\filldraw (ball) circle (0.05cm);
\draw[-FARROW] (o)node[right]{O}--(e) node[right] {$x$};
\draw[-FARROW] (i1)--(i2) node[right] {$\VEC{i}$};
\end{tikzpicture}
Here's the output

Perhaps something like this:

I hope that these line widths are just for demonstration purposes and you don't really want to use these:)
