1. An approved helmet that fits securely. Replace it if you think it is damaged. A white or brightly coloured helmet can help you to be seen.
2. Good clothing - and that means jackets, trousers and boots. The best is CE marked and can protect you from getting hurt if you come off. It should be fluorescent during the day and reflective at night.
3. Clothing which also protects you properly from the weather will not just make you feel more comfortable, it will also allow you to focus more on your riding.

Make sure your visor is not dirty or scratched and remember not to wear a tinted visor or goggles at night.
