led running brake light circuit for motorcycle?
i want to add 5 LEDs wired for 12 volt in parallel to my motorcycle running lights. then when brake is pressed they will light up brighter. i think i need to add a resistor to each input ( brake and running light wire) to drop voltage down. maybe 9 volts for running lights (which would be on all of the time) and another 3 or 4 volts for the brake light so added to 12 to 13 volts for bright brake lights. any ideas how do i do this and what size resistor i should use or am i looking at this wrong?
