Backup Lights vs. Reversing Lights
This is chiefly a regional terminology difference. Collins maps US “backup light” to British “reversing light,” while UK vehicle-lighting legislation uses “reversing lamp.” The page explains the naming difference, not every jurisdiction’s equipment requirements.
“Backup lights” is the usual US term; “reversing lights” is the British term for the white rear vehicle lights used when reversing. UK regulations also use the related formal term “reversing lamp.”
