Lighting is not an aesthetic detail. Headlights and bulbs define how much you see and how much you are seen — during the day, at night, and in the rain.
For those just starting out, a short checklist helps avoid common mistakes and also adds value to the car when it’s time to sell. There are three straightforward items, focused on safety.
1) Full operation: everything lights up when it should
It seems obvious, but failures go unnoticed because not everyone tests the car from the outside. Do the check with the vehicle running and, if possible, ask for help.
Check one by one: - Low and high beams (both sides) - Position lights (parking lights) - Front and rear turn signals - Brake lights (press the pedal) - Reverse light and license plate light
Practical tip for beginners
Park the car close to a wall at night. The reflection makes it easier to see if one side is weaker or off. Any burned-out bulb becomes a reason for inspection failure and a bargaining point in negotiation.
2) Alignment and aiming: see without blinding
Misaligned headlights reduce visibility and bother oncoming drivers. It’s a real risk, especially on poorly lit roads.
Warning signs: - Beam “looking” at the ground or too high - One side lights more than the other - Drivers frequently flash their headlights at you
What to check without equipment
With the car on level ground, observe whether the beams are at the same height and direction. Many models have manual adjustment in the engine bay or on the dashboard. Fine adjustment at a shop is quick and usually inexpensive.
3) Bulb type and condition: standardization and upkeep
Mixing bulb types (one halogen and another different type, for example) creates uneven lighting and confuses distance perception.
Check: - Pairing: always replace in pairs - Similar color temperature (avoid very different tones) - Lenses without cracks and without excessive yellowing
Watch out for the “modern” look
Overly bright bulbs or ones outside the factory standard can worsen real lighting and cause issues during inspections. For selling, simple and correct usually appeals more than flashy.
Common mistakes that undermine safety (and value)
- Ignoring the license plate light - Driving with a fast-blinking turn signal (a sign of a burned-out bulb) - Using tape or makeshift fixes on a cracked lens
Before listing the car
Reviewed lighting conveys care. Buyers notice it on the first drive and use it as a thermometer for the rest of the vehicle. A simple checklist avoids friction, improves day-to-day safety, and makes negotiations cleaner.
