Automotive Headlight Assemblies

Check your vehicle's make, model, year, and trim level; match the assembly's vehicle compatibility list and part number to your VIN when possible, and confirm whether the unit is for left/right side and for models with or without fog/leveling features

Replace the bulb if only the lamp is burnt out and the housing is intact; replace the full assembly if the housing is cracked, sealed incorrectly, has moisture ingress, or if the reflector or internal components are damaged

Compare construction (OEM-style vs aftermarket), light source compatibility (halogen, HID, LED), mounting points, adjuster and leveling compatibility, lens material (polycarbonate vs glass), and whether plug-and-play wiring or ballast/adapters are required

Prices typically range from lower-cost budget options under $50 to several hundred dollars for high-end or OEM-style assemblies; average aftermarket assemblies commonly fall around the low hundreds depending on vehicle fitment and included features

Many assemblies are designed for DIY installation using basic tools like screwdrivers, socket set, and pliers; more complex fits may require removing bumper components, aligning aimers, or handling electrical connections, so consult the vehicle repair manual and product instructions

Ensure proper sealing by installing all factory gaskets and vent caps, avoid blocking vents, check for cracked housings or damaged seals, and allow the assembly to acclimate after installation if it was stored in cold conditions

Aftermarket assemblies can change beam pattern and aim; always adjust headlights to the manufacturer's specifications after installation and confirm the assembly meets local regulations for beam pattern and light output to maintain road-legal operation
