Quick Summary
- A streetlight inspection drone captures the luminaire, lens, photocell, mast arm, and pole top from above, where a truck crew usually needs a bucket to look.
- Day flights show physical damage and day burners. Night checks show outages. Most programs need both.
- The photos only pay off when each one is tied to a light ID, tagged by severity, and turned into a grouped work order.
- Utileyes organizes drone photos by GPS location and asset ID, so streetlights can ride along on the same flights as distribution assets.
A streetlight inspection drone is a small camera drone flown pole to pole to photograph each light's fixture, arm, and pole top so crews can find damage without a bucket truck. It works best as a planned route tied to your streetlight inventory, not as a one-off flight.
Utileyes builds drone inspection software for utilities, and streetlights come up often with city-owned systems and co-ops that maintain lighting on their own poles. This guide covers what a drone can see on a streetlight, how to run the flights, and how to turn photos into repairs.
If you already fly distribution lines, you are most of the way there. Streetlights share poles, crews, and work queues with the rest of the system.
What can a streetlight inspection drone actually see?
A streetlight inspection drone can see the top and sides of the luminaire, the lens, the photocell, the mast arm and bracket, the pole top, and any shared attachments. It cannot confirm a lamp works in daylight, and it adds little at the pole base, where a ground walk is faster.
That top-down view matters. Many streetlight defects face the sky or sit behind the fixture head, out of sight from the street.
Common findings from above
- Lens and housing damage: cracked or yellowed lenses, missing covers, and water or debris inside the head.
- Photocell problems: a missing, cracked, or misaimed photocell. A photocell is the small light sensor that switches the fixture on at dusk and off at dawn.
- Arm and bracket issues: a sagging or twisted mast arm, loose bracket hardware, or a fixture tilted out of its aim.
- Wiring and attachments: exposed conductors at the arm, damaged drip loops, and nests built into the fixture head.
- Day burners: lights that stay on during the day, usually from a failed photocell. These are easy to spot on a daytime flight.
Photocells are worth extra attention. A DOE-backed national inventory survey, as reported by Electrical Contractor, found that most surveyed luminaires were switched by photocell controllers.
How do you inspect streetlights with a drone, step by step?
Start with a clean map of every light, then fly a planned route that captures each fixture from the same angles. Upload the photos so each one attaches to its light ID, review and tag defects by severity, and send grouped repairs to crews. The process is the same whether you own 500 lights or 50,000.
- Map every fixture. Import pole and light locations from a KML or CSV file. If your records are thin, asset points can be generated in flight.
- Set a standard shot set. Keep it short: one oblique view of the fixture head, one top-down view of the lens and photocell, and one view of the arm-to-pole connection.
- Fly the route. Assign pilots to blocks of lights on a map, and capture each light on the same flight as the distribution assets on that pole.
- Upload and sort. Drag-and-drop uploads should sort photos by GPS metadata, and QA should flag images that landed on the wrong asset.
- Tag and dispatch. Reviewers tag each finding by safety, outage, or monitor priority, then route grouped work orders to crews.
The Utileyes workflow follows this same order, from asset mapping through crew dispatch.
Day flight or night patrol: which finds more streetlight problems?
Neither one finds everything. Day flights find physical damage, misaimed fixtures, and day burners. Night patrols find outages and dim or cycling lamps. Most lighting programs pair a periodic daytime drone inspection with outage reports and night drive-bys, then send the drone where the night data points.
| Check | Daytime drone flight | Night drive or patrol |
|---|---|---|
| Lamp out | Not visible | Clear |
| Day burner (photocell failure) | Clear | Not visible |
| Cracked lens or housing | Clear, including top side | Hard to see |
| Mast arm sag or bracket damage | Clear, close up | Hard to judge |
| Fixture aim and tilt | Clear | Shown by light spread |
| Wiring at the arm | Clear, close up | Not visible |
| Cycling or dim lamp | Not visible | Clear |
Night drone flights are possible but add planning. Check current FAA rules for night operations and your own safety policy before you schedule them.
How do drone inspections reduce truck rolls for streetlight repairs?
Drone inspections cut truck rolls by showing crews the problem before they leave the yard. A crew that knows it needs a new photocell, a lens, or an arm bracket brings the right part, and nearby repairs get grouped onto one trip instead of several separate visits.
Without photos, a lamp-out report often means two trips. The first trip finds the cause, and the second trip brings the part.
Where the savings come from
- Right part, first trip: the work order carries the photo, so the crew knows what failed.
- Grouped work: severity tags let a supervisor bundle low-priority fixes on the same street or circuit.
- Fewer look-and-leave visits: lights that look fine from above can be cleared without a bucket inspection.
- Shared flights: streetlights on distribution poles get captured during line inspections you already fly.
Running inspections in-house with Utileyes comes in at about 50% lower inspection cost than outsourcing to vendors.
How should you organize streetlight inspection photos?
Organize streetlight photos by light ID first, then by inspection date. Every image should attach to one fixture record, carry a severity tag, and stay linked to past inspections of that same light. That structure lets a supervisor filter by street, circuit, or priority and see the history in one place.
Folders named by date and pilot fall apart fast. A single block of lights can produce hundreds of images in a day.
A simple severity scheme for streetlights
- Safety: exposed wiring, a hanging fixture, or an arm at risk of falling. Dispatch now.
- Outage: a failed photocell, a broken lens with water inside, or a dead fixture. Schedule soon.
- Monitor: minor fading, light corrosion, or a small tilt. Recheck next cycle.
Adjust those labels to your own standards. Utileyes lets each utility set severity levels by outage risk, fire hazard, or safety priority, with customizable inspection forms.
How Utileyes handles this in practice
Utileyes was built with utility linemen and drone pilots. The founders personally flew more than 10,000 utility inspections, and the leadership team has over 50 years of combined utility operations experience.
That background shows in the workflow. Photos sort automatically by GPS location and asset ID, QA flags misplaced images during upload, and a finding can go from photo captured to crew dispatched in as little as 15 minutes. Results export as an ArcGIS/ESRI-compatible CSV, and the platform integrates with existing GIS and work order systems.

Is your streetlight inventory ready for drone inspections?
Your inventory is ready if every light has a location, an ID, and a basic fixture type. If it does not, the first drone pass can fill those gaps. Many cities and utilities find their lighting records are incomplete, and an asset map built during flights becomes the record going forward.
That gap is common. A drone street lighting audit project recognized by the Galileo Masters competition was built around the problem that manual audits are slow and costly and municipal lighting data is often incomplete.
Start with what you have. Load the KML or CSV you already keep, fly one district, and fix the map as you go. Then expand block by block. Our solutions page covers other asset types you can add to the same program.
Frequently Asked Questions
Can a drone tell if a streetlight is out?
Not in daylight. A daytime drone flight cannot show whether a lamp turns on at night. Pair drone inspections with outage reports or night patrols, and use the drone to find the cause.
What is a day burner?
A day burner is a streetlight that stays on during the day. It usually points to a failed or misaimed photocell. Day burners are easy to catch on a daytime drone flight.
Can streetlights be inspected on the same flight as distribution poles?
Yes. When a streetlight sits on a distribution pole, add the fixture shots to that pole's shot set. One flight then covers both assets, and the photos sort to each asset's record.
How many photos does each streetlight need?
Three is a practical starting point: an oblique view of the fixture head, a top-down view of the lens and photocell, and a view of the arm-to-pole connection. Add more only when a defect needs a closer look.
Do drones replace ground inspections of streetlight poles?
No. Drones cover the parts that are hard to see from the street. Pole bases, handholes, and ground-level wiring are still faster to check on foot.
Do we need our own drones to get started?
No. The Utileyes FAQ explains how teams with no drones get started through partners, including hardware recommendations and Part 107 training resources.
Put your streetlights on the map
Streetlight inspections work when every photo lands on the right fixture and every finding reaches a crew. Utileyes was built in the field, not in a conference room, to make that happen.
