      Hello guys, I have had this question for at least 35 years, and until now, I havent found the answer. (Not that I have asked it a lot)

      But I now realsie that you good ppl, will most probably be able to answer them for me.

      You know all buses, esp double deckers, have these 2 small lights at either sides on the top of the buses. Some hv it at the back as well, these 2 purple, pink or red lights (usually) near the roof.

      What are they for? Surely it can be a warning of it's height or is it? Even newer buses have them. It cant be for the drivers to see heighst either, the lighst are too small and ineffective, so what are they for?

      Any clues? Thanks

      No light = what happened to SBS9400X just that it is night time.

      Yeap, you've guessed it. That Volvo Olympian that became a single deck whilst on service 87. Some dead.

      Hope you got your answer. It is more of a height warning at night.

      Especially for low flying aircrafts flying in open areas. Not really applicable in urbanised Singapore but just as a safety precaution.

      More common for tall vehicles in USA, Australia, Europe and other parts of Asia.

      yes, the height warning is the true answer

      most tall buildings if u notice, they have this light (always red) installed on the corners or the top of the buildings

      at night, they light up, warning low flying aircraft of such hazards

      of couse, these lights are unable to warn birds though
