Adorning yourself with loads of lights makes 0 difference to how noticeable you are in the majority of situations where people think it makes the most difference.
You can spend a lot of time to make yourself as visible as it is possible to be with multiple lights, helmet lights, hi-vis, reflective jacket, pedal and spoke reflectors, tyres with reflective side walls, reflective tape on your bike frame.
Recent stats suggest that "driver failed to look properly" is a contributory factor in something like 1/3 of road accidents in Scotland so ride like everyone is out to kill you is sensible advice.
