My small N scale layout has 7 turnouts. I want to fit bu-colour LEDs to the control panel so that when a turnout is thrown the main line shows red and the branch shows green, when the turnout is thrown again the main shows green and the branch is red. The LEDs are wired through a switch under each turnout with a common positive. Each LED has 3 leads, one for red, one for green and a negative. The negatives are also common wired. The red lead of one LED is connected to the green of the second LED and vice-versa so that the two LEDs for each turnout are on all the time but showing either red or green depending on which way the turnout is thrown. My problem is that the reds are quite bright but the greens are dim. Is there some way I can get both colours about the same? I can operate on either 5V or 12V. On 5V the total draw for the 14 LEDs is about 300milliamps. If I put resistors on each LED it will affect both the red and green and even though the red might be a bit dimmer it would probably shut the green off completely. Does anyone have a solution please.
