An emergency lighting system that can be used on any vehicle where the standard lighting system installed on the vehicle is malfunctional, especially at the rear of the vehicle, due to shorting out or other causes. The emergency lights consist of units having various colored lights therein, such as red, white or yellow that are normally recognized in any traffic pattern. The lights can be operated from the standard battery of the vehicle or can be switched to a battery system contained in the light units. This is especially true in vehicles towing a boat or a trailer. When the boat is launched into the water, the lights on the trailer may be submerged into the water thereby shorting out the electrical system. This renders the towed vehicle illegal in traffic on the highway because the rear lights are not functioning. The inventive concept of this invention solves the above noted problem.
