Laser headlights have longer irradiation distance (up to 600m) and higher energy efficiency than LED headlights, with smaller lamp body volume; LED headlights have lower cost, more mature after-sales, and better compatibility with most pickup and truck models. Laser headlights are more suitable for high-end heavy-duty trucks and long-distance driving, while LED is the first choice for daily pickup modification with high cost performance.
Focus on three core parameters: wattage matching (consistent with the original car’s power supply to avoid circuit damage), beam type (low beam with cut-off line to prevent glare, high beam with long range for off-road), IP rating (IP67 or above for dust and water resistance, suitable for truck outdoor working conditions). In addition, choose models with plug-and-play design to reduce modification difficulty
The main reasons are the over-bright modified bulbs (exceeding the legal brightness standard) and the deformed headlight reflector/lens (causing beam deviation). Solutions: Replace the qualified original factory or certified modified bulbs; maintain the headlight lens regularly to avoid yellowing and deformation; choose headlights with adaptive anti-glare function that can adjust the beam angle according to the oncoming vehicle.
US FMVSS 108 stipulates that the maximum brightness of low beam is 2000 cd, and high beam is 7000 cd (cd is the unit of luminous intensity). Modified headlights must pass the DOT certification, and it is illegal to install ultra-bright bulbs without certification or remove the original lens for blind modification. Once fined, the penalty is $50-$200, and the vehicle needs to be rectified within a time limit.
Replace the assembly if there are these problems: The lens is severely cracked or deformed (cannot be repaired by polishing); the internal reflector is oxidized and discolored (resulting in serious beam attenuation); the circuit board inside the headlight is short-circuited and burned (multiple bulb replacements still fail); the assembly is loose and water enters frequently (affecting the normal use of electrical components).
