I added a red blinkie to my left front fork last night.

This only works on BMX and Mountain bikes that have a round fork tube.

The Blinkie is aimed slightly to the left.

It does get "eclipsed" by my left foot every time I push the left pedal.

I put it there mainly to avoid getting "right hooked".

I have another red blinkie on the seat-post and a green blinkie facing forward, on the handlebars.

I keep them on steady mode.
