In the lessons

In everyday life and safety, streetlights help people see and be seen when walking at night; children are often told to be home «when the streetlights come on». In science, pupils learn about light sources, and that streetlights use electricity and often LED bulbs. In maths, streetlights appear in spacing problems. Phrases: «under the streetlight», «the streetlights came on».

Examples

Note

Also written «street light» or «streetlamp». Maths trap (fence-post problem): a 90-metre road with a light every 30 metres at both ends has 4 streetlights, not 3, because you count the first one too.
