If you stand your bike at a T junction, at night with both lights on, and then walk down the road so that you are viewing it from side-on, you will be staggered by how little it shows up. One solution to this would be to use two lights, both pointing slightly away from 'straight ahead'. As lights are cheap, light, and easy to re-charge nowadays, it might be better to use two cheap ones rather than one expensive one. The other advantage of this is that if one of the lights did fail or flatten you would still have one working one.

Some thought should also be given to where you position your rear light(s). I have seen many bikes with a rear light aerodynamically positioned under the saddle. Sounds great, but is totally invisible from a lorry that is less than 10 metres behind you!!!

Hi-viz with reflective hoops are really good - the one like the motorway maintenance workers wear offer 360 degree visibly.
