as it stands to day there is no certification authority to authenticate quality of LED bulbs. So many spurious organizations have come up. the bulbs fail so frequently, that it shakes our faith in the technology. So government should come out with certification agencies.
all the signals in the road should be replaced by LED cluster lights. it should be made mandatory. it also serves another purpose. signals will function smoothly even without main power supply.
