Abstract

An electric lighting apparatus for a bicycle includes a relay (R) to connect the bicycle lamps (L1, L2) either to the bicycle dynamo (G) or to a battery (B) depending on the dynamo output voltage. The apparatus includes a relay control circuit formed by three transistors (T1, T2, T3) which is connected to the dynamo, via a time lag section (R1, R2, C1) and a parallel switched dynamo load (R6) to prevent unwanted switching of the relay due to changes in the dynamo output voltage when the lamps are connected to its output. The quiescent current of the apparatus is sufficiently low to enable the battery (B) to be permanently connected. <IMAGE>
