Commercial Sign Lighting Repair in Las Vegas & Henderson
Dead channel letters, flickering storefront signs, and failed transformers cost you visibility every night they stay dark. Penny Electric repairs and retrofits commercial sign lighting across Las Vegas and Henderson — licensed, code-compliant electrical work for illuminated signage.
What Sign Lighting Repair Involves
Commercial sign lighting repair covers the electrical side of illuminated signage — diagnosing dead or flickering channel letters, failed transformers and ballasts, damaged wiring, and burned-out lamps, then repairing or retrofitting them (often to LED) to get your sign lit again. Because signage runs on higher-voltage and often exterior-rated components, it's electrical work for a licensed contractor. Here's when a business sign needs a licensed electrician.
This work is part of our complete commercial electrical services for Las Vegas and Henderson businesses — licensed NV C-2 #74758, $950K bid limit, code-compliant installs with minimal disruption.
Sign Problems We Fix
Channel letters partially or fully unlit
Dead or dim letters often trace to a failed power supply, wiring fault, or lamp failure — we diagnose and repair the electrical cause.
Flickering, buzzing, or intermittent sign lighting
Loose connections, failing ballasts, and overloaded transformers cause unstable sign lighting that needs professional repair.
Storefront, pylon, or monument sign gone dark
When an entire sign goes out, the fault is usually at the transformer, circuit, or main feed — we find it and restore power.
Old fluorescent or neon signage you want retrofitted to LED
LED retrofits cut energy costs and extend sign life — we convert older illuminated signage to modern, efficient LED.
