from page 210 of the owners manual...
to replace the headlights (low beams)...
remove the clips from your engine plastics.
remove the engine plastics - in doing so, also remove the washer hose from the notch on the cover
unplug the headlight electric connector (if the connector is tight, wiggle it)
remove the rubber cover
release the bulb retaining spring and remove the bulb along with the socket. install new bulb into the socket and return the bulb retaining spring to its original position.
(to install a bulb, align the tabs of the bulb with the cutout of the mounting hole)
install the rubber cover with the "TOP" mark upward, and snuggle on the boss. Insert the electrical connector.
(make sure the rubber cover fits snugly on the connector and the headlight body.
Aiming is not necessary after replacing the bulb. When you believe aiming adjustment is necessary, contact your Toyota dealer
last step - re-install the engine plastics
(always notch the washer hose before fastening it when installing the engine plastics. This prevents washer hose damage.)
