Your vehicle should be inspected about every two years to ensure it is safe to drive. Your vehicle inspection will cover a number of different items, including lighting. From the headlights to the dashboard lights and on to the tail lights, your vehicle's lights will be given the full once-over.
The following list of lights will be inspected: headlights, brake lights, backup lights, stop lights, license plate lights and turning signals. Each needs to be in full working order to pass the inspection. You dashboard lights will also be inspected, but may not need to be working perfectly for your vehicle to pass.
There are two dashboard lights that you should be concerned about during an inspection -- the air bag light and the brake light. If your air bag light is always on or will not light, you will fail an inspection because these indicate serious problems in your air bag system. Your brake lights may also cause you to fail an inspection. If the light signals a failure in a hydraulic break system, you will fail the inspection. Meanwhile if the light signals a problem with an anti-lock brake system you will pass but will be advised to have the brakes checked.
Your headlights must be the correct kind and give the appropriate amount light. The headlights must also be in good working order with the proper wiring. They should have a fully functional switch and beam indicators.
Tail Light Inspection
Missing or cracked tail lights will cause you to fail an inspection. All the lenses and reflectors need to be intact, unobstructed, free from cracks and clean to pass. The tail lights cannot be fixed with adhesive tape, but an epoxy glue fix may be passable.
Neon Undercarriage Light
Only some states will allow cars to have neon undercarriage lights, so check your state guidelines before having them installed. Remember, all after-market lighting must be approved by your state motor vehicle department and the Department of Transportation.
