Are Position Lamps and Width Indicator Lights the Same?

[GageRose]

Position lamps and width indicator lights on vehicles are not the same. Width indicator lights are small yellow lights located at the front and rear of the vehicle, commonly referred to as 'double-flashing' lights, which indicate the width of the vehicle. Position lamps, on the other hand, are the outermost lights at the front and rear of the vehicle. Differences between position lamps and width indicator lights: There is not much difference between position lamps and width indicator lights; the distinction mainly lies in the terminology used for different vehicle types. Width indicator lights are more commonly found on large vehicles such as buses, trucks, and coaches. Position lamps: When position lamps are illuminated at night, other vehicles can estimate the approximate length and width of the vehicle, helping to prevent accidents caused by obscured vehicle dimensions in the dark.

I've been repairing cars for over a decade. Position lamps and width lamps are actually the same thing - they refer to those small lights on both sides of the front and rear of a vehicle, specifically designed to illuminate during nighttime or low-light conditions so others can clearly see your vehicle's width and outline. National standards uniformly call them position lamps, but some people are accustomed to calling them width lamps - there's no essential difference, as both serve to prevent accidents. If you drive at night without turning them on, police may issue a fine, or worse, you risk getting rear-ended. Checking the bulbs is quite simple - most vehicles use halogen or LED bulbs. If they're out, it's usually due to a burnt-out bulb or wiring issues. Just spend a few dozen yuan to replace it with a new one, don't delay as it affects safety.

The first time I drove, I was confused about these two names—position lights and width indicators are actually the same lights, located at the front and rear of the car. I usually turn them on at night or in foggy weather so that vehicles behind can see how wide my car is, avoiding accidental scrapes. I remember once being pulled over by a police car and warned for not having them on, and since then, I’ve made it a habit to check their brightness when parked. Bulb aging is the most common issue; they typically last a few years. If one burns out, just buy a replacement at an auto parts store and change it yourself—it’s not difficult. In short, though small, they are crucial for safety.

From a safety perspective, the clearance lights and width marker lights are part of the same lighting system, primarily designed to make your vehicle's outline visible to other drivers during dusk or in poor weather conditions, thereby reducing the risk of traffic accidents. If these lights fail, it can easily go unnoticed but may lead to rear-end or side collisions, hence regulations mandate their operation. During inspections, simply ensure the bulbs are intact and the wiring is properly connected.
