Rear lights

[beardydave]

Is there anything about angle of viewing for the indicators and brake lights?

Do you have to be able to see both of them from a 45deg angle to the back of the car for example?

I've planned to extend the back of the car out by a couple of hundred mm from the book spec to fit my longer range fuel tank in, so if i put the lights on the rear wheel arches you'll only be able to see one of them when you move too far away from perpendicular to the back of the car.

And do the indicators have to be further out than the brake lights or tail lights?
