Troubleshooting Address Sign Sightlines: Fixing Shadows, Glare, and Obstructions
Troubleshooting address sign sightlines starts at the curb, not on the porch. If a driver cannot read the house numbers from 40–50 feet, the plaque can be working and still fail. Shadows from eaves, glare from a flood, and obstructions such as shrubs or a parked SUV are the usual culprits.
Stand where a delivery van actually stops. If the numbers disappear behind a branch or wash out in a spotlight, move the sign or the obstruction before you change hardware.
Shadows vs glare vs obstructions
| Problem | What you see | Fix | | --- | --- | --- | | Shadows | Dark band across digits at dusk | Drop the plaque below the eave or shift off a column | | Glare | White blob; numbers unreadable | Aim floods down; use a matte plaque face | | Obstructions | Digits clipped by shrubs or vehicles | Trim, or move the sign to the mailbox side |
Sightline checklist
- Walk the approach at night, not only from the driveway.
- Check both directions if the street is one-way for mail but two-way for EMS.
- Trim anything inside a 45-degree cone from curb to plaque.
- Confirm the light sensor is not staring into a porch flood.
- Recheck after seasonal growth.
