As of 2022, a front light is compulsory for all time trials run under the rules and regs of Cycling Time Trials, the UK’s governing body - that goes for both open and club TTs.

A rear light has been mandatory since 2020, with most testers now having settled on their favourite unit that does the job of both making them visible and not losing them too many watts in aerodynamic drag.
