I've a bike where a 35W Head light bulb glow on AC from alternator.
There is High Beam pilot bulb indicator on my meter which glow along with head light on AC
means both get a same power from same source switch.
This AC volts fluctuate with acceleration about minimum form 6-7 i think to 12v max (regulated).
Now, i want to change a meter high beam indicator to LED.
But led needs a constant DC power. Connecting with a battery will not work.
Only I can do is to convert the AC to DC for only one LED.
How can I do that?
Both bulb shares a ground so i can say i've a single wire with fluctuated AC volt.
I want a led to be a constant glow.
Do I need a bridge rectifier? or a single diode will do the work?
Also what rating capacitor do I need?
and a 1k resistor for sure.
Please give me schematic.
Thanks
