Why do Civic lights stay on during the day?

Civic lights stay on during the day because the installed lights are daytime running lights (DRLs). To enhance driving safety, all new vehicles are required to have DRLs, which are mandatory and do not have an off switch. Daytime running lights are front-mounted lights that make the vehicle more visible during daytime driving. Below is additional information about the Civic: 1. Civic generally refers to the Honda Civic: The CIVIC is Honda's legendary model, first introduced in 1972. Over 47 years and through ten generations of innovation and evolution, it has gained recognition and trust from 25 million users worldwide. From its inception, the CIVIC has embodied Honda's spirit of continuous challenge and breakthrough, making it Honda's core and iconic model. 2. The Honda Civic (CIVIC) offers multiple models to cater to the tastes of consumers in different countries: (1) Three-door hatchback. (2) Hardtop coupe. (3) Hybrid version and five-door sedan version. 3. The Honda Civic launched in China shares the same production platform as the Dongfeng Honda CR-V, with both vehicles using the same chassis. This provides the technical prerequisites for the domestic production of the Honda Civic.

I recently noticed that my Civic's lights are still on during the day, and after some research, I found out that this is a daytime running light (DRL) system specifically designed by Honda. Daytime running lights are not the headlights or taillights, but rather a set of specially designed LED light strips that automatically turn on when the vehicle starts. The primary purpose is to enhance driving safety during the day, such as making your car more noticeable to other drivers earlier in rainy weather or under shaded areas. Another reason is due to new regulations, as many countries now mandate that new vehicles must be equipped with this feature. I checked the user manual and confirmed that this function cannot be manually turned off on the Civic, as it is a standard safety design from the factory. However, if you notice all the lights in the headlight assembly are on during the day, it might indicate a sensor malfunction, and you should have it checked at an authorized service center.

My Civic is the same, the light strips are always on during the day. Actually, this is the daytime running light (DRL) function, which is now a standard feature in most new cars. It's particularly useful when driving, especially on highways through tunnels or under overpass shadows, making it easier for vehicles ahead to notice your presence. Moreover, LED light sources are very energy-efficient, not as power-consuming as headlights. I've specifically compared it with other cars, and the Civic's DRL positioning is ingeniously designed with moderate brightness that doesn't glare. The only thing to note is if the DRL suddenly stops working one day, it might be a fuse issue or poor wiring contact, requiring a check. Just be careful not to block the headlight gaps when washing the car.

It's perfectly normal for the Civic to have its lights on during the day. My car came like this from the factory. The salesperson said these are daytime running lights (DRLs), specifically designed to improve visibility during daytime driving. Research data shows they can reduce daytime accident rates by 26%, and they've been mandatory in Europe for a long time. The working principle is simple: they automatically turn on when the ignition is on, without needing to use the light switch. The difference from regular headlights is that only the front slim light strips illuminate, while the rear taillights remain off. They're about half as bright as headlights, which is a very reasonable design. If you find it strange to have them always on, you can visit the dealership to see if they can disable it through programming, but I recommend keeping this safety feature.
