In Karnataka, backlit and frontlit signboards are commonly used for effective advertising and visibility. Backlit signboards illuminate from behind, creating a glowing effect that enhances visibility at night. Frontlit signboards, on the other hand, are lit from the front, offering clear and vibrant signage during the day. These signboards are popular in urban areas like Bengaluru, serving businesses, restaurants, and shops. They provide eye-catching displays, improve brand recognition, and attract potential customers by standing out in both day and night settings.
