Abstract:
A vehicle may include a tail light and a brake light. The tail light may be used at night or in other low light or low visibility conditions to indicate the presence of the lead vehicle to a vehicle or a person traveling behind the lead vehicle. The brake light may be used to indicate that the brakes are being applied to the lead vehicle. The brake light may be a shade of red in color. The tail light may be a different color than the brake light. For example, the tail light may be blue, green, purple, brown, shades of these colors, or variations of these colors. The tail light is a different color to distinguish the lighted state of the tail light from the activation of the brake light.
