Choosing correct capacitor

[bsab44]

I have connected a mini ac alternator to a motorcycle engine to run some led lighting. The alternator specs are voltage range 3-24v, current 0.1A - 1A, rated power 0.5 - 12w. The light bulbs are voltage range 1.5 - 9v ac/dc, output 0.5 - 1w. The system works but I want to connect a capacitor to keep the lights bright when the alternator is running at low rpm. I cannot work out what type or size capacitor would be suitable. Thanks for any advice.

Will not work.

Will not work.

Agreed.

Use the alternator (plus rectifier and charge controller) to charge a battery. Run the lamps from the battery.

Have to agree with Harald. It makes most sense.
