I'm sure they're all blindingly stupid, but I'd appreciate all answers...

1. What are tail lights?
2. How can I check that my headlights and main beam work during the daylight?
3. What fluid do I use to fill up the engine coolant tank?
4. What fluid do I use to fill up the brake fluid resevoir?
5. What fluid do I use to fill up the windscreen washer resevoir?
6. What does the Highway Code mean by 'old style number plates'?
7. What's a soft verge and what's wrong with soft verges anyway?

Told you they were stupid. Still, better to look like a fool now and ask a question than to not ask a question and remain a fool forever.
