High power 5mm LEDs
Warning: requires current limiting resistor (average current max 80 mA) ! Do NOT directly apply 12V or even 5V !
Useful for indication light (shiftlight, warning light, etc...), timinglight, or checking operation of ignition and injection outputs (and effectively trigger input).
For a given current, blue gives the strongest light, red is somewhat dimmer and green is considerably dimmer. Consider this when making timing-light.
