Adding ambient lights in the car will not cause spontaneous combustion, but it may affect the electrical circuit, potentially leading to circuit burnout. The load is relatively high for xenon headlights, while other lights have a smaller load. Therefore, it depends on whether the engine capacity is sufficient. Owners can increase the cross-sectional area of the wires to enhance load-carrying capacity, thereby reducing heat generation and avoiding issues like overheating and fire. Additionally, ensuring proper insulation is crucial to prevent short circuits. Ambient lights, also known as LED ambient lights, are a type of LED lighting and are an excellent choice for theme parks, hotels, homes, exhibitions, commercial spaces, and artistic lighting, creating the desired atmosphere for people's lives. Individuals can customize their preferred lighting scenarios based on personal lighting needs (such as color, temperature, brightness, and direction).

Last time I helped my cousin modify the ambient lighting, I specifically researched the risks of spontaneous combustion, which mainly occur during the installation process. For example, forcibly cramming wiring harnesses into dashboard gaps can wear through the insulation, or randomly tapping power from the fuse box can cause circuit overloads. Qualified products themselves generate very low heat, but if installed near plastic components in the air conditioning ducts, prolonged exposure to high temperatures can indeed make them brittle and melt. It's recommended to go to a certified modification shop—they will lay flame-retardant fabric inside door panels to isolate wiring harnesses and leave a 20% margin for fuses. Don't cheap out on uncertified light strips; last year, a local SUV had smoke due to a short circuit in its light strip. After modification, monitor for two weeks, and immediately cut power if you smell burning.

In ten years of auto repair, I've encountered two cases of spontaneous combustion caused by ambient lighting. The first involved a car owner DIY-installing light strips with double-sided tape. The adhesive melted from heat, causing the strip to fall into the seat rail where metal components crushed and short-circuited it. The second case was even more outrageous – using household electrical wires connected directly to the battery terminals. The wire insulation melted due to engine compartment heat. Actually, the safest method is using the factory-installed reading light power outlet, keeping power under 5W. Always avoid routing wires through airbag deployment paths – during collisions, broken light strip fragments can become projectiles. Immediately discontinue use if you notice flickering or localized blackening on light strips.

From a physics teacher's perspective, spontaneous combustion requires three simultaneous elements: combustible material (inferior light strip packaging), oxidizer (oxygen), and ignition source (short-circuit sparks). Qualified products use flame-retardant PC + solid adhesive encapsulation - at most causing fuse melting rather than fire during short circuits. However, modified cigarette lighter continuous power supply frequently leads to battery drain. Starting a vehicle in this depleted state causes sudden voltage fluctuations that easily puncture LED beads. Tests show a popular magnetic ambient light's peak startup power reaches three times its rated value - such power surges pose significant risks to aging wiring.
