the orange beacon light is also used by those who hold offices at the airport areas where access is through the runway

the rule is, once you approach any of the gates (for example delta gate along airport road), you are supposed to put your blinker on your roof. however, once you exit the airport gates, you are supposed to remove this

i had one once, about 10 years ago. one time, i totally forgot to remove it and didnt realize that it was still flashing as i was travelling from the domestic airport up to makati. hindi naman ako pinigil. some time later, a friend of mine called me and said he saw me and wanted a light like that one also, mwahahahaha
