i have used rectifier ckt , but this time the capacitor is of 16v 1000mf, connection is right, it worked for one week if there is wrongly connected diodes then it won`t work for one week, but now when i switch on the scooter, on idle the L.E.Ds glows but the moment i rev the scooter L.E.Ds goes off
i think there is problem in diodes

Your brake light is powered by AC. You will have to convert it to DC using a bridge rectifier before using the same power line to light up the LEDs. Else, if you have already used the rectifier, the connections are not proper (maybe the diodes are connected wrongly wrt polarity).

^^ Oops! I meant the 3 console back-lighting bulbs, not the 4 tell tale lights.Leave a comment:

the three different bulbs of 2w are for different use one for high beam, one for right indicator & other for left indicator & 4w bulb is for brighten up the console, so use of power from any one bulb's wires & removing the bulbs from the other 2 holders and leave them as it is won`t work here, so the duty is performed by good old bulbs,& those 3 lights hardly remain ON all the time

^^ Well, my aim was power saving at that time. Since those lights hardly remain ON all the time, so left them as it is!Leave a comment:

Use power from any one bulb's wires. (And all 3 bulbs are 1.8W each.) Remove the bulbs from the other 2 holders and leave them as it is. And no. my neutral, high beam and other lights are still normal bulbs!Leave a comment:

there are 4 bulbs in the console 3 are of 2 watt & 1 of 4 or 5 watt, & each need it`s separate bridge rectifier ckt to light up one L.E.D, so dropped the idea
for indicator, high beam, side stand & neutral did you use single L.E.D[but in pulsar you have them powered by dc so there is no need for the ckt for each one of them]

^^ Didn't get what you are trying to say. My tail light was AC too.. used a brigde rectifier (it has 4 diodes + 1 cap) to convert to DC. See the ckt on the 1st page.Leave a comment:

that ckt ,i have used for tail light , have to make it in different manner, or i may let the old bulbs to do the workLeave a comment:

^^ Use a bridge rectifier together with a capacitor. That will convert AC to DC.Leave a comment:

my speedo bulbs uses a.c power , how can i make L.E.Ds to work on it reply quickly guys, thanksLeave a comment:
