In the last few weeks, there has been a new look on the traffic lights in Jogja. Some of them has been replaced with a newer version which has bigger and brighter lamp than the previous one. Another advantage of the new light is that most of it has a timer, reflecting how many seconds left before the light turn to red, yellow, or green. This will allow the driver to predict when to stop and when to go on a crowded street.
Unfortunately, the placement of the timer sometimes aren't in the best place, because there are trees that stand before them, making the timer not in the good sight for the driver. I think they should have cut the tree's branch in order to make the timer visible. Some places still uses the old (and sometimes broken) lamp, so i hope all light will be replaced sometime in the future.
