I return to one of my pet topics - mainly because I have a prime example on my commute and it can be a danger! The scenario is always a truck or other large vehicle waiting correctly before the first ASL, me coming up the inside on the painted filter lane, or alternatively overtaking on the right, or alternatively hanging back which is the only safe option, but loses me time... Trouble is, I don't know when the lights are about to change as I approach: I can't see the lights facing the other way at that point. If they change while I'm filtering I then don't have much time! Overtaking on the right can be dodgy too, since this is a T-junction for motorists, and large vehicles are often turning into my road. I go straight on along a cycle path. My mind, today, after being faced with just such a situation (I hung back ) - wandered across to France where they have these small 'repeater' traffic lights at eye level - mainly as a courtesy to motorists who don't have to crane their necks to see the main lights. But useful to cyclists too. My thought is, why not position some sort of small repeater light, but on a separate pillar alongside the filter lane, five to ten yards back from the main cluster (so that the leading motorist can't see them) - and timed to show red-and-amber five seconds before the main lights change. Sort of to give the cyclist an early warning that he is approaching a dangerous situation. In fact you wouldn't need the full red-amber-green set, just a single amber light lit at a suitable time to warn the cyclist. Does this make sense to anyone?
