An apparatus includes a current control circuit configured to selectively provide current responsive to a varying voltage to at least one LED coupled in series with the first current control circuit and to at least one capacitor coupled to the at least one LED and the first current control circuit. The current control circuit may be configured to cause the at least one capacitor to be selectively charged from a current source and to be discharged via the at least one LED responsive to a varying input, such as a varying current from the current source or a varying voltage applied to the current source. For example, the current control circuit may be configured to limit current through the at least one LED to less than a current provided by the current source.
