Car lights stay on during the day because daytime running lights remain constantly illuminated while driving. Precautions for modifying car lights are as follows: 1. Power saving: Original halogen headlights typically consume around 60W of electricity, whereas HID gas discharge headlight assemblies, with the help of stabilizers, only require 35W-40W to power the xenon bulbs for illumination. This significantly reduces the burden on the vehicle's electrical system and correspondingly enhances the car's performance. 2. Brightness: HID lights can output up to 3200 lumens of brightness, while standard factory halogen bulbs can only produce about 1000 lumens at most. This means that after upgrading to xenon headlights, the brightness can increase by 300%, providing illumination that is brighter, wider, and farther-reaching, ensuring no dark corners are left unlit and offering additional safety for nighttime driving. 3. High color temperature comfort: HID lights emit light with a color temperature of approximately 6000K, which is closest to the effect of daylight and offers the highest level of acceptance and comfort for the human eye. Such lighting effectively reduces driver visual fatigue during nighttime driving, significantly improving safety after car modifications.

What are the functions of compression rings and oil rings?

Compression rings serve to seal the gap between the piston and cylinder, preventing gas leakage and oil blow-by, while also transferring heat from the piston to the cylinder. Oil rings function to scrape excess lubricating oil off the cylinder walls and distribute oil evenly on them. Here are some relevant details: 1. Compression rings: Typically, each piston in an engine is equipped with 2 to 3 compression rings. If compression rings fail to seal properly, it can lead to various issues such as difficult engine starting, reduced power output, and increased fuel and oil consumption. 2. Oil rings: Oil rings come in two types: conventional oil rings and composite oil rings. They are a type of piston ring, usually made of alloy cast iron. The outer circumference of an oil ring features a central groove with numerous small drain holes or slots at the bottom for oil passage.
