The automotive technical inspection is a comprehensive examination, with 133 points scrutinized, potentially leading to up to 610 defects. Among the many points of attention, the verification of lighting is obviously included. The objective of the technical inspection is to ensure that your vehicle is clearly visible and does not disturb other road users.
Lighting, the main point of failure leading to a re-inspection
The "lighting/signaling" function (now "lights, reflective devices, and electrical equipment") is the second most common non-conformity in technical inspections. Since the tightening of inspection rules in 2018, many motorists are therefore obligated to make rapid repairs if their car does not meet the requirements!
Fog lights and high beams are now checked, as are low beams, brake lights, parking lights, and license plate illumination devices. So, what lighting elements are checked when your vehicle undergoes a technical inspection?
- Headlights: In addition to their operating condition and conformity, light intensity and any malfunction of the control device are also checked;
- Front, rear, and side position lights, daytime running lights, and clearance lights: conformity verification includes ensuring the light is the correct color (white at the front, red at the rear);
- Brake lights;
- Turn signals and hazard lights, fog lights, and reverse lights;
- Reflectors, reflective plates, and reflective visibility markings;
- Lighting and electrical equipment (battery, electrical wiring, electrical connection, headlight washers, charging sockets, etc.).
To avoid any unpleasant surprises during the technical inspection, it is important to regularly check the operating condition of all vehicle lights. The dashboard should also not display an error with an illuminated warning light.
Our tips for consistently functional lighting on your vehicle
For your vehicle to truly comply and provide a total level of safety, you need to go beyond a simple visual check before the technical inspection. In fact, you should ensure quality lighting all year round.
If your vehicle has an adjustment system, remember to balance the lights (left and right) or adjust the headlight settings according to the vehicle's weight. For example, with a full trunk when going on holiday in summer, you will need to lower the headlight beam to compensate for the effect of the weight on the vehicle's attitude.
When a bulb stops working, do not limit yourself to replacing just one. Since headlight bulbs work simultaneously, if one fails... the other should follow suit! It is therefore recommended to replace lighting devices that come in pairs at the same time.
Finally, for truly effective lighting at all times, it is recommended to change bulbs every three to four years. With this preventive replacement, you will maintain the quality of the luminous flux (with halogen), guaranteeing powerful lighting.
