Blue flickering headlight - Safer?

[men8ifr]

From my driving and riding I notice in the dark a bike's headlight sometimes I cannot tell from a car (could be one cars headlight) and since I cannot see or make out the other light I cannot tell how far away he/she is (the biker). This is worst with lots of cars on the road behind you so you cannot 'pair' headlights together to tell exactly where the cars are (or bike)

Also If I see a bike with a red/green/blue (not blue tint but BLUE) headlight I know it is a bike straight away - it also attracts your attention - you SEE it. More effective still are headlights which appear to flicker maybe this is the bike jolting up and down a bit maybe slightly dodgy electrics or maybe a unit to make the flickering? but I would say you are 10x more likely to see a flickering blue headlight and know it is a bike over a standard white lamp.

The best examples I have seen are sportsbikes.

So if I were to ride on the road a lot (which I dont) I would try to get one of these for my safety - the only downsides I can think could be getting pulled by the cops, you need a second lamp to do this I don't think relying on a blue lamp to see the road is very good and the cost/effort to put a blue bulb in.

Similarly a flickering (or even flashing) rear light would be more effective, sometimes if on a country road with a car following I touch the brake quite a bit so the brake light flashes and they cannot miss me (or hopefully do miss me!)

Any comments, would you do this is it a good / bad idea?
