The technical difficulty of car headlight modification is very low. Whether it is an LED headlight that directly replaces the bulb assembly, or a xenon headlight that requires the installation of a ballast, the simple wiring and assembly replacement can basically be learned by watching the tutorial. Gotta know. This has caused many modification shops or individual users to blindly upgrade lights without considering the safety and potential risks of the vehicle. The most common mistake is to blindly increase the power of the bulb.
What is the wattage of the bulb used in car headlights? Other types of modified bulbs should also comply with this standard, because the carrying capacity of the line matches the wattage of the original car bulb. A higher-power light bulb will naturally consume more power. Assume that the 55W light bulb is replaced by a 100W large light bulb. The essential concept is to increase the energy consumption from 55 joules per second to 100 joules per second; the current carried by the wire is excessive. It will inevitably cause the temperature to exceed the standard. What will be the result?
Upgrading the power of light bulbs by a large proportion will cause the insulation layer of the wire to soften, that is, it will melt after being heated. The insulation layer of the rubber material will melt every time the light is used, and will solidify due to natural cooling after the flame is turned off; the insulation layer will crack under the action of repeated large temperature differences, and can peel off in severe cases. So once the wires come into contact with a short circuit and catch fire, will the risk of spontaneous combustion of the vehicle be much higher? The answer is obviously uncontroversial.
Key point: The fuse in the circuit cannot withstand the excessive current. According to the actual test, the 35-watt light bulb was upgraded to 65-watt. After a short period of use, the two headlights went out at the same time. The reason is naturally that the fuse is blown. Just imagine if the headlights suddenly go out during a long-distance drive, can the vehicle continue to drive? And what to do if you can't stop on the highway? The result is nothing more than driving in the dark and the speed must be above 60km/h, and you must only drive in the right lane where large vehicles can pass.
Have you considered the feelings of the lamp housing?
Test results on used vehicles show that using super-standard light bulbs will bake the lamp shell; of course, the cost of the headlights is high and no test was conducted, and the time required to bake the fog lamp shell is very short. Regardless of halogen, xenon or LED headlights, these bulbs will generate very high temperatures after being lit. For example, xenon bulbs will have a high temperature of about 300 degrees Celsius after being lit, and LED headlights that are said to have extremely low temperatures will also reach 100 degrees Celsius. Above, even brake lights with LED lamp beads are no exception.
Many vehicles using headlights with a power of more than 100 watts will burn out the lampshades sooner or later, and it is questionable whether the reflector bowl can withstand the increased high temperature standards. Therefore, it is not advisable to blindly increase the wattage when modifying car lights. Normal xenon or LED headlights with 35 watts are considered bright enough, but the color temperature will feel warmer. The highest standard for normal modifications is not recommended to exceed 55 watts, because the wattage of the bulb is different from the Color temperature is inevitably related. High-wattage cold-light lighting will feel poor in actual use. Headlights that are too bright may easily cause misjudgment of obstacles. Modifying car lights should not be too exaggerated.
