Hi, first post and new to designing curcuits.
What I would like to do is try to design or buy one or two bridge rectifiers to convert 12v ac to 12v dc.
The purpose of this is to custom make a led tail light/brake light for my snowmoblie. The complete curcuit must fit inside a 7/8" square aluminum tube that the tail light will flush mount into.
From what I've been reading a rectifier will turn 12v ac into 16.8v dc unless a resistor is used to correct this?
What I need to have happen when the curcuit is complete is to have the tail light on when the motor is running and have the brake light brighten when I apply the brake. I have three wires that go to the stock lighting system now. Hot (12v ac), ground and hot (12v ac) when brake is pressed.
Do I need to have two rectifiers for this (one to each 12v ac source) or can one be used for both hots?
If I use a string of 16 1.5v led lights will it light with what I'm guessing is the correct voltage of 16.8v dc. Can I then connect the second hot to the same string and have them turn brighter when the brake is applied? The string of leds would be in parallel. The reason for do this is to have them under powers when motor is run and overpowered when the brake is pressed. Will overpowering the led string by 33% cause the string to blow out right away or just shorten the life of the string?
Or would it be better to run two stings of 8 leds, one for tail light and one for brake light and just stager the lights?
Thanks
