In addition to dash indicator lights, which external lights and reflectors should be checked?

Check that all external lights and reflective equipment are clean and functional. Light and reflector checks include:
- Clearance lights (red on rear, amber elsewhere)
- Headlights (high and low beams)
- Taillights
- Backing lights
- Turn signals
- Four-way flashers
- Brake lights
- Red reflectors (on rear) and amber reflectors (elsewhere)
- Reflector tape condition
