City of Tyler Streetlights are primarily maintained and repaired by Oncor Electric Delivery. With nearly 7,000 lights in our city and 180,000 in our district, Oncor Electric Delivery appreciates the numbers of watchful eyes. Streetlights are installed in the public right-of-way for the purpose of illumination of roadways for easier navigation by motorists, typically at intersections and on curves. Streetlights are not intended to be the primary security lighting for households and businesses. Residents and business owners are encouraged to examine their security and lighting needs and consider installing fixtures on their property.
