# Electrical Systems

## Battery

Most modern car batteries are **maintenance-free**.

- Keep terminals **clean, secure, and lightly greased**.
- If your battery has filler caps, ensure the plates are covered with fluid and top up with **distilled water** if needed — but don’t overfill.

## Lights

Check all lights (front, rear, brake, indicators, and hazard) **before every journey**.

Use reflections in windows or walls, or ask someone to help.

Carry **spare bulbs and fuses**, and replace any that fail immediately.

**Headlights must be correctly aligned** to:

- Avoid dazzling other road users.
- Provide clear visibility ahead.

All lights must:

- Be **clean** and **fully operational**.
- Emit a **steady light**.

Indicators must:

- Flash at a steady rate (1–2 times per second).
- Show the **correct colour**.
- Be clearly visible.

## Windscreen Washers and Wipers

- Check that washers and wipers work properly.
- Keep washer reservoirs filled — use proper screen wash for effective cleaning.
- Replace **worn or damaged blades** promptly.
- If fitted, maintain **headlight washers** to the same standard.

Carry spare washer fluid or clean water, especially in muddy or wet conditions.

## Horn

Test the horn regularly to ensure it sounds clearly.

Use it responsibly to **warn others** — not to express frustration or alarm people unnecessarily.
