At Lighthouse TG, we know that even the best-installed signals need consistent upkeep to stay safe and reliable. Our Traffic Signal Maintenance services are designed to reduce downtime, extend system life, and keep your intersections operating smoothly no matter the time of day or traffic load.
- Preventative maintenance programs to minimize costly outages
- 24/7 emergency response for damaged or malfunctioning signals
- Routine inspections, testing, and fast-response troubleshooting
We service all aspects of traffic signal systems, from signal heads and controllers to detection systems, wiring, and communication links. Our crews work efficiently with municipalities, contractors, and DOTs to ensure every signal operates to code — with safety, visibility, and performance as top priorities.
Our maintenance service includes regular cabinet inspections, controller testing, signal head alignment, lamp or LED replacement, wiring and grounding checks, and detector system calibration. We also offer knockdown response, storm damage repair, and full intersection diagnostics to restore safe operation quickly. All services are logged, reported, and performed in line with MUTCD and local standards.
