Demon eyes will not turn off when the headlights are on. The difference between angel eyes and demon eyes: Both angel eyes and demon eyes are luminous circular cathode tubes. The difference in their installation positions leads to distinct visual effects. Angel eyes are installed on the lens cover, while demon eyes are installed inside the lens. Essentially, this is the only difference between angel eyes and demon eyes. The prerequisite for installing demon eyes is that your car must either come with a lens or have one installed first, followed by adding the demon eye inside the lens. The light reflects off the spherical lens, creating a visual effect resembling an eyeball. Demon eyes give off a fierce and cool visual impression. Pros and cons of angel eyes and demon eyes: From a purely practical standpoint, angel eyes are much easier to remove than demon eyes, reducing the likelihood of poor sealing due to disassembly. Angel eyes are installed outside the lens and do not obstruct the light path, whereas demon eyes are installed inside the lens, which can somewhat affect the width of the light source.

















I've seen many car enthusiasts ask this kind of question. Actually, 'demon eyes' usually refer to those bright daytime running lights used for decoration. When you manually turn on the headlights, on most vehicles, the demon eye lights will automatically turn off or dim. This is standard design because the headlights are brighter, making it unnecessary to keep the daytime running lights on and waste electricity. I've driven several cars myself that work this way - the factory system prioritizes headlight illumination to ensure nighttime safety. However, if the demon eyes are aftermarket modifications, like strips you added yourself, the behavior might not be consistent. It depends on the installation method. Some older car models have different wiring setups that may prevent them from turning off. In such cases, it's best to have an auto shop check the circuitry to avoid affecting visibility. In summary, it's normal for demon eyes to turn off when headlights are activated during regular driving.

As a frequent driver, I've noticed that during daily driving, if you first turn on the demon eyes (those cool small lights) and then switch on the headlights, they often automatically turn off. For example, my family's SUV behaves this way, designed to save power and reduce distractions, avoiding excessive brightness at night that could affect others. I suggest you try this operation in your car: start the vehicle to let the demon eyes light up, then manually turn the headlight switch, and in most cases, it will turn off instantly. However, be cautious with modified lights, as some non-original parts might be improperly set, causing continuous operation that could drain the quickly or create light interference. Remember to inform the technician during regular maintenance to check the lighting system, ensuring stability and avoiding negligence. Driving safety comes first, and proper light adjustment ensures peace of mind.

From a safety perspective, when the headlights are turned on with the demon eyes (angel eyes) illuminated, the demon eyes usually turn off. This prevents light confusion, allowing the headlight beams to focus on illuminating the road, reducing the risk of nighttime accidents. My personal experience is to check the vehicle manual to confirm the settings.

I've modified the lighting systems on several cars. Decorative lights like demon eyes often turn off automatically when the headlights are on. However, if you've rewired the system yourself or used third-party accessories, they might stay on, wasting energy instead. It's recommended to consult a professional shop during installation to ensure compatibility.

Regarding the issue of car lights, it is common for the demon eyes to turn off when the headlights are on. This helps the vehicle save power and prolong the bulb's lifespan. I've personally noticed that factory cars are set up this way to avoid rapid battery drain from multiple lights. If you want to keep the demon eyes on with the headlights, you may need to adjust the settings at a shop, but be careful not to violate regulations and affect other drivers.
