Try adjusting the series resistor. A higher value vill get rid of the dim off state, the drawback is that the on condition will probably be less bright too.
Odd anomaly though... could be that your LED driver is damaged? Do you know the reason why the LED board was missing in the first place? Maybe someone was tring to do some repair work? (like a glowing HDD LED... :-D )
@Hodgkinson & Zac67, how about this:
* Beginning from the bottom of the component (where the solder pins are); cut the LED almost apart, leaving only the top 1-2mm. Use a thin blade or a Dremel disk.
* Then paint the whole thing black, except from the top and solder pins (use masking tape, and dip the whole thing in paint).
This method should give:
* an unchaged look compared to an unmodified LED
* The same color on both sides
* No need to buy/find LEDs that match the original dimensions
I will give it a try myself. Stand by for pictures...
