This is an idea for a pretty basic bicycle dynamo taillight with a standlight. It is intended to be connected in parallel with the headlight, with an input voltage of 8 to 9 volts.

I've run some simulations on it, but have not built it. It is pretty simple though.. Adjust R3 to change the current through the LEDs. Adjust R2 and C1 to change how long the standlight runs (and how long it will take to charge the standlight).

Take out one pair of parallel LEDs if the headlight voltage is less than 8v.

From left to right: Bacon Apple Maple, Spiced Chocolate, Lemon Thyme....delicious.
