conspicuity

An Airprox Board report said neither aircraft was "equipped with any form of electronic conspicuity equipment".

The goal, in a word, is conspicuity — making yourself and your bike highly visible to other road users.

Martin's A Song of Ice and Fire Series, Daenerys mentions that no Targaryen has ever ridden more than one dragon — a detail pointed out by Reddit user No_conspicuity.

"There's very little background signal here - we've got very high conspicuity," Dr Caravan said.

Standard 108 of the Federal Motor Vehicle Safety Standards and Regulations says vehicle headlights must be capable of reducing "traffic crashes and deaths and injuries resulting from traffic crashes, by providing adequate illumination of the roadway, and by enhancing the conspicuity of motor vehicles on the public roads so that their presence is perceived and their signals understood."
