They did install a not-working LCD on a TIB5xx...or was it
TIB8xx. Anyway, the LED is most likely to be a display telling
commuters what the next stop is, probably installed in conjunction
with the GPS. If you notice, the LED is now displaying SIngapore
because the GPS tells us so that we ARE in Singapore. SMRt will
probably amend the LED & GPS to tell the exact location
