The GUIDE LITE^® is a lightweight, snowplowable, raised pavement marker. It is tested to NTPEP. Made of a durable plastic material with abrasion resistant steel rub rails, the GUIDE LITE^® weighs substantially less than similarly sized cast iron markers. Installation involves using standard industry reflectors, slot cutting equipment, and adhesive. GUIDE LITE^® is designed to allow for snow plows and other road maintenance equipment to glide over the product, without cast iron debris.
