I am an A-level product design student, for my my major project i have
decided to design and make indicators to put on a bicycle. My initial
idea is to put a device with indicators and a brake light on the back
of the bicycle connected to the seat post so people travvelling behind
the cyclist can see what the cyclist intends to do and then put a tube
with a amber light on the end fixed onto either end of the handlebars
so people aproaching from the front can see if the cyclist intends to
turn. If anyone has any ideas on this please post a reply .... it can
be possitive ... negative ... doesnt matter all replys will be useful

Brake lights have been done already. Nashbar has one:

into them: http://tinyurl.com/uo7m

Turn signals have been done as well, I had them on a bike as a child.
They're quite common on mopeds and if I was going to put some onto a bicycle
I would just use the same system as a moped or scooter. It would be just as
important to have turn signals that are visible from the front as well as
the back. I don't know about where you live, but around here people in cars
do not use their turn signals, so I doubt signals on a bicycle would do
anything ... people don't even use lights on their bikes at night.
