99. Dipped beam

Dipped beam is the low-beam setting of a vehicle's headlights. It illuminates the road ahead while directing the light downward so that it is less likely to dazzle drivers and other road users.

Dipped-beam headlights are normally used at night, in poor visibility and whenever main beam could dazzle another road user. They provide less illumination than main beam but are suitable for normal driving when other traffic is nearby.
