Steps
Match the replacement lamp
Use the VIN to confirm the correct left or right assembly, lighting technology, and connector layout. Compare the replacement with the original before removing trim, and protect the fenders and bumper with covers.
Create access to the lamp
Switch off the lights and ignition, then remove the required upper covers and retainers. Release the bumper-cover fasteners and clips in the sequence specified for this RX350, keeping the cover supported to prevent paint damage.
Disconnect and remove the old assembly
Unplug the headlamp connectors and free any harness clips. Remove the assembly fasteners and guide the lamp out without levering against the painted fender or bending its mounting tabs.
Prepare the new assembly
Compare mounting points and connectors, then transfer bulbs or brackets only if the replacement requires them. Keep the lens clean and avoid touching exposed bulb glass.
Install and align the lamp
Connect the wiring, position the assembly, and start its fasteners by hand before tightening to the vehicle specification. Refit the bumper cover and clips, test all lighting functions, and have headlamp aim checked before night driving.
Check your vehicle’s repair manual for exact specifications and fit.
