Has anyone fallen for the mistake of being out in the wilds (no street lights) and finding the small twin headlights approaching in the mirror are not a car still some distance away but a bike actually much closer.

I've been caught by that one as well. Yamaha R1's are the worst, with their headlights spaced well apart. The twin lights on many bikes don't actually illuminate the road any better than a good single light.

Eurpean law now requires one only to be illuminated as you may have noticed on new bikes; not sure whether retro-fitting is stipulated.

Had a mate hear the other day on his new Triumph triple. He was saying the bikes come with just the one lamp but that all the boys re-wire them to get two.

Been watching Band of Brothers so going to stick my head above the parapet only for a very short time, but of course despite the illegal wiring naturally it would STILL be ALL the car drivers fault.

Be fair! If we have one lamp go, we can save our necks with the other! Why deny that small benefit to bikers?

Hi Tomo,
Tongue was very firmly in cheek with that last post.
Could say I had gone fishing.

Wierd! Cars have to have two headlights - why is it a problem for bikes?

In theory:
Because most paired vehicle headlights are usually more than 1.5m apart.
On a bike they are no more than 6 cm apart.
Given that the bikes conventionally have only one headlight, the brain
automatically treats the two 6cm apart lights as being a four wheeled
vehicle. Once this assumption is made the brain then works out the distance
using perspective, but the basis that the lights are more than 1.5m apart, leading to a gross over estimation of the distance.
