I remember seeing them in a catalogue (Cricklewood Electronics, possibly)
when I was still at school.  I must have been in 4th or 5th year of high
school (Americans - the UK school system is very different from the US
system, and I have no idea how this relates to your high schools) so I was
probably 15 or 16.  So, 1989-1990 seems about right.  I do remember the
line in the catalogue:

BLUE LEDS ....................... £40 (yes, forty pounds)

We were amazed at the time (Ooooh, blue LEDs, oooh $expletive, how much?!)
