These don't fit the Kingbright bicolour LEDs
These fit the kingbright single colour LEDs well, but the bicolour LEDs (such as 56-0620) do not clip properly in to them. (The hole is the right diameter, it it the clipping mechanism that does not work - at any rate for the bicolour mentioned.) The three star is for this application - work very satisfactorily for the single colour LEDs
