How to hook up one LED light with two 6v sources? Answered
I'm trying to hook up a tail/brake light on my moped and I'm wondering if its possible to use the one light for both brake and tail light. The light itself is a closed housing with two leads coming off the back, see the diagram as I'm probably not going to explain things all too well. The moped has three wires that originally powered two separate incandescent bulbs and the third wire being the ground completing the circuit. The brake light is only lit when I squeeze the brake lever where there is a switch that connects and sends the power back to the light.
Is there any way to connect these two wires into the one lead that could result in an increased brightness when I complete the brake lights circuit? My thinking is that I can put a resistor on the 'tail light (constantly fed)' lead and when the 'brake light' lead has power, the light will get the full 6v and become brighter. Am I close to being right about this? How can I keep the 'tail light' power from traveling through the 'brake light' wire? I know theres something I'm obviously missing here, its been a while since I've worked with voltage and maybe its not possible but I'm hoping theres a way.
