Yeah, but your clips are your problem, not theirs.
There's nothing wrong in slowing down hoping to catch the green light, most people do that, but there's a difference between slowing down gradually and crawling. Remember that drivers are not used to bike, especially those riding in the lane. And as Roughstuff said, bikes don't have break lights so it makes bikes more difficult to predict. Don't slow down too slow too quickly and signal your intentions.
