Does the citroen c3 exclusive have full beam?

All modern cars have full beam.

Try reading your owners manual, if you can't operate your car then you should not drive as you are a danger to other road users, what else do you not know how to do?

(left pedal is for stopping by the way, usually the middle one but you obviously can't change gear either!)

The full beam is located on the lighting stalk (duh)

To use it flick the lighting stalk towards you. This will turn on full beam if you are on dipped beam, or if your lights are off it will give you a single flash.

If it truly doesn't work then you obviously have a problem, in which case you have wasted your time by asking this question as your car is still covered by the standard 3 year manufacturer's warranty, so instead of asking people on Yahoo Answers (who for the most part know nothing about your car) then you should be asking the technicians at your local Citroen dealer to fix it for free.
