SENENQU 4 x 4 inch Yellow Road Reflectors — 12-Pack Durable Retroreflective Pavement Markers, Weather-Resistant PE/ABS

SENENQU 4 x 4 inch yellow road reflectors are heavy-duty pavement markers that boost nighttime visibility and define lanes, driveways, crosswalks and speed bumps.

These 12 pavement studs are engineered from weather-resistant PE/ABS materials to withstand sun, rain, snow and vehicle traffic while providing up to 100 meters of retroreflective visibility. Each marker measures approximately 100 × 100 × 20 mm and includes a simple base for fast mechanical or adhesive installation, making them a practical option for roads, parking lots, sidewalks, driveways and construction zones that need durable, highly visible delineation.

How do these reflectors improve nighttime safety?

When light from vehicle headlights hits the reflectors, the retroreflective surface sends light back toward the driver, making lane edges, speed bumps and crosswalks easier to spot. Their bright yellow color and reflective surface increase contrast in low light and bad weather, helping drivers detect changes in the road sooner.

• Visible up to 100 meters under vehicle headlights
• Yellow color enhances contrast against asphalt
• Retroreflective surface returns light to drivers for faster recognition
• Works in rain, fog, and low-light conditions

What material and build quality can I expect?

These studs are made from durable PE/ABS-grade plastics chosen for impact and weather resistance. The construction is intended to tolerate vehicle traffic and exposure to temperature swings without cracking or quickly losing reflectivity.

• Premium PE/ABS materials for long-term outdoor use
• Robust shell resists UV, moisture and road salts
• Flat base designed for secure fixing with screws or epoxy
• Each unit measures about 4 × 4 × 0.75 inches

How are these markers installed and maintained?

Installation is straightforward: clean the pavement, then secure each reflector with construction adhesive/epoxy or mechanical fasteners. For the best longevity, use an asphalt bonding epoxy that covers the entire underside; periodic cleaning will keep reflectivity optimal.

• Surface prep: remove debris and dry the area
• Recommended adhesive: asphalt binding epoxy or construction glue
• Alternative: countersunk screws for mechanical fastening
• Maintenance: wipe debris and inspect adhesive annually

Where are these reflective studs best used?

They’re suitable for many outdoor surfaces where clear visual guidance is needed. Common applications include private driveways, public streets, parking lots, bike paths, pedestrian crossings, speed bumps and temporary construction zones.

• Driveways, private roads and garage entrances
• Crosswalks, speed bumps and lane delineation
• Parking lots, sidewalks and bike paths
• Construction sites or mailboxes needing reflective markers

Who is this for? SENENQU 4 x 4 inch road reflectors are ideal for property owners, facilities managers, municipal crews, parking lot operators and contractors who need a cost-effective, long-lasting way to improve road-edge and hazard visibility. If you manage a driveway, small road, parking area or temporary traffic zone and want a simple, weatherproof marker with high retroreflective performance, this 12-pack offers a balanced combination of visibility, durability and easy installation.
