Motion-activated exterior lighting is one of the smartest, most affordable upgrades a homeowner can make. It deters intruders, trims electricity bills, and delivers hands-free convenience every night. Yet the question every client asks first is simple: “What will it cost to install motion sensor lights?” CountBricks answers that question in minutes—backed by AI precision and decades of residential construction experience.
• Builder-grade units start around $25 each and offer basic detection ranges
• Premium LED fixtures with smartphone integration can exceed $250 apiece
• Swapping an existing light on a wired junction box is quick and inexpensive
• Running new cable through finished walls or long soffits increases labor hours
• Ground-level garages or porches require minimal equipment
• Two-story eaves often need scaffolding or boom lifts, adding rental fees
• Basic on-board sensors are plug-and-play
• Linking lights to whole-house smart systems may require additional hubs, setup, and testing
• Most municipalities classify fixture swaps as maintenance—no permit fee
• New circuits or exterior conduit can trigger electrical permits and inspections
Across hundreds of suburban installations, CountBricks records a typical spend of $180 – $420 per fixture, all-in. The low end reflects a direct replacement using existing wiring. The high end covers premium fixtures, ladder time over 20 ft, and smart-home integration. Because every home is unique, CountBricks recommends an on-site or blueprint-based estimate before budgeting.
1. Fixture: $115 (LED, 180° sensor, dusk-to-dawn mode)
2. Electrical supplies: $22 (wire nuts, caulk, junction box cover)
3. Labor: $145 (licensed electrician, 1.5 hours)
4. Smart hub pairing: $35
Total per light: $317
Traditional estimates rely on manual takeoffs, handwritten notes, and days of back-and-forth. CountBricks compresses that timeline into a real-time conversation:
• Speak your project details into the CountBricks mobile app
• AI scans live pricing from regional suppliers and labor databases
• In seconds, you receive a line-item proposal ready to send or sign
For contractors, that speed means winning more bids. For homeowners, it means transparency before a single ladder is set up. Explore the workflow at CountBricks.com/services.
• Choose fixtures that match your actual coverage needs—oversized wattage wastes money
• Consolidate multiple installations into one visit to minimize labor mobilization fees
• Opt for LED units with built-in photocells to eliminate extra wiring for manual switches
• Schedule work during daylight to avoid premium evening rates
• Use CountBricks AI takeoffs to catch material overlaps and avoid over-ordering

When the Johnson family purchased a 1950s bungalow in Fresno, they loved the charm but worried about the dark side yard. They contacted CountBricks through the voice intake feature and described their goal: two motion sensor lights, Wi-Fi control, minimal wall damage.
• Existing porch light junction box identified via uploaded photos
• 38 ft of new 14/2 exterior-rated cable required for the second fixture
• Two 1,200-lumen LED floodlights with 270° sensors selected from local inventory
The platform generated a $612 proposal covering materials, labor, and a modest permit fee flagged by city code. The Johnsons approved electronically within ten minutes.
