Most of the time, hand signals are not enough to keep the cyclist safe; especially under circumstances of poor ambient illumination. Therefore, turn signal lights are included in Smart Helmet to serve as directional indicators and break lights to further increase the probability that the bicycle will be noticed.
most motorcycle accidents occur because car and truck drivers do not see bikers. Many motorcycle accidents occur because small bikes are hidden in blind spots or because motorcycles are harder to detect at night or in poor weather conditions.

If you're riding at night, you absolutely should be using a front headlight. It's required by law, anyway. Even for daytime riding, a bright white light that has a flashing mode can make you more visible to motorists who might otherwise Right Cross you.
