Part of speech: n
Definition: A car headlamp that provides a bright, centre-weighted distribution of light with no particular control of light directed towards other road users' eyes; as such, it is only suitable for use when alone on the road, as the glare it produces will dazzle other drivers.
Example: International ECE Regulations permit higher-intensity high-beam headlamps than are allowed under North American regulations.
