Wearing a hoodie that said "DEAF" on the back in capitals

Can't think of a good title.

Anyway, seeing that I'm deaf and tend not to recognised sound (incoming car, police/ambulance/fire engine sirens, people going OI!.) and even a simple wind blowing at my hearing aids will sound like a radio with no reception, so trying to listen is impossible, also poor balance which mean if someone hit me I'd come down a cropper (you need to able to hear properly in order to have good balance).

Riding around London is alright, I tend to spend a lots of time looking over my shoulder and observing the road ahead more often as if I was cycling with a NoBrake, no worried there really, but in the evening run back to South Wimbledon from Bloomsbury at 2am can get quite scary with children speeding in their car/scooter, police/ambulance/fire engine literally pop up from behind, driver driving too close to me, etc.

Would having a bright red hoodies with 'DEAF' in white helvetica (none other than) on the back would make a bit of a difference or not?

Brilliant idea, do it.
