This for leds,
Easiest is a small bridge rectifier smallest rated is about 1 to 2 amps rating is not important as leds only draw milliamps (ma), 20 ma is the maximum i use even though most have a maximum rating of 30 ma above 20 ma will shorten their life, the high brightness ones are normally bright enough at 10 to 15 ma, i always use a separate resistor on each led to limit the current as even if from the same batch the brightness of each may be different,
i e only example values, you may need a 330 ohm resistor on one and a 390 ohm on the other to get the same even brightness.
The bridge rectifier will come with the ac side and the + positive and - negative output marked,
Two wires soldered to the ac side go to the motor though marked ac a bridge rectifier will accept a dc input on the ac side as well, the motor can be reversed the input polarity will change swop sides but the output + and - will remain constant and will not change, the leds connect the same + to + and - to -
The bridge rectifier will put no load on the motor what so ever.
You could use 4 silicon diodes in a bridge configuration but what confuses most peeps, the ring marking on a diode denotes the cathode - negative end it is the two - cathodes soldered together is the positive + output, early metal ones were marked with + and - signs, idiot who brought out the ring system of marking what a doughnut.
