Lighting & Fault Diagnosis
Headlights, warning lights, and electrical fault tracing.
From headlights that won't work to dashboard warning lights that won't go away, lighting and electrical fault diagnosis covers a wide range of problems. Mobile Auto Elec uses professional diagnostic tools to identify the actual cause rather than guessing or just clearing codes.

Dashboard Warning Lights
We read fault codes across all vehicle systems — engine, ABS, airbag, transmission, TPMS, and body control modules. Understanding what a code actually means (not just what it says) is the difference between fixing the problem and replacing parts that weren't faulty.
Frequently Asked Questions
It depends on the stored code. A solid check engine light is usually not an immediate emergency but needs to be diagnosed. A flashing check engine light indicates an active misfire that can damage the catalytic converter — reduce speed and get it diagnosed urgently.
Yes. In most cases a blown bulb, blown fuse, or failed relay can be diagnosed and fixed on-site. On some modern vehicles with adaptive headlight modules, more involved diagnosis may be required.
No — clearing codes without fixing the underlying fault just makes the light go away temporarily. The code will return as soon as the fault condition is detected again. Proper repair requires identifying and fixing the actual cause.
