A range of 3mm LEDs which can be connected either way round As the power source can be anyway round these are ideal for any application which uses reversable power supply. Model railways is a good example as it does not matter which way the track power is, the LED will still stay lit up. For example if used on Model Railway trains head lights they would light if the loco was going forward or backwards. The red could be equally be used for the rear end of the train.
