Will the heat from LED lights damage the lamp cover?

This type of headlight generates relatively low heat, so it will not damage the lamp cover. Here is some relevant information about LED headlights: 1. Energy-saving and low cost: LED lights have high luminous efficiency, nearly twice that of fluorescent lights. For the same daytime running lights, the energy consumption of LED components is only 1/20 of that of halogen lamps. The cost of LED components has also significantly decreased year by year, and currently, the cost and price continue to drop by more than 20% annually. 2. Excellent durability: LED components have a simple structure, excellent impact and shock resistance, are not easily broken, and can adapt well to various environments.

I previously installed LED headlights myself and didn't pay attention to the heat dissipation issue. As a result, the headlight housing got deformed during long-distance driving. The heat from LED lights is concentrated on the back of the LED chips. If the heat sink is too small or the fan is ineffective, the heat can't dissipate, making the headlight housing as hot as a steamer. Regular plastic headlight housings can only withstand temperatures up to around 120°C. Poor-quality LED lights with inadequate heat dissipation can easily exceed 150°C, causing yellowing and deformation at best, or even burning holes in severe cases. Therefore, I recommend choosing LED lights with copper tube heat dissipation + dual ball-bearing fans when modifying, ensuring proper ventilation gaps during installation, and ideally adding a temperature sensor for real-time monitoring. Regularly cleaning dust from the headlight housing is also crucial, as dust buildup can worsen heat accumulation.

My neighbor learned this the hard way. Trying to save money, he installed a set of no-name LED headlights which melted a hole in the housing within six months. The mechanic found paper-thin heatsinks and broken fans during disassembly. Actually, quality LED lights nowadays come with built-in thermal control chips that automatically reduce brightness to protect the housing when overheating occurs. I recommend avoiding unverified online products - while OEM upgrades cost more, their thermal designs are far more reliable and maintain the original vehicle ventilation structure. For DIY modifications, always measure the rear temperature; if it exceeds 85°C, additional cooling measures are necessary.

In theory, LEDs generate less heat than halogen bulbs, but the temperature of the LED base plate can still reach 70-80°C. Many modern vehicles use plastic lamp housings for weight reduction, but their heat resistance is actually limited. If high-power LEDs are forcibly crammed into a small, sealed housing without proper heat dissipation, prolonged high temperatures can cause the plastic to become brittle and crack. The worst case I've seen involved a deformed housing that lost its seal, allowing rainwater to seep in and short-circuit the entire electrical system. Therefore, when modifying, it's crucial to consider heat dissipation space and avoid exceeding the original vehicle's designed power rating.
