Step 1
Open the hood of the ES300 and prop it open.
<LI id=jsArticleStep2 itxtvisited="1">Step 2
Look at the headlight assembly from the top down. Depending on your model year, there may be a plastic panel covering the top of the headlight assembly. If this is present, remove it by lifting all of the plastic clips around the edges and lifting it off.
<LI id=jsArticleStep3 itxtvisited="1">Step 3
Locate the three bolts that hold the headlight assembly in place. Two of the bolts are in the left and right rear corners of the assembly, and the third is on the side bordering the outside edge of the car, screwed into the back of the fender panel. Remove all of these bolts with a small adjustable wrench. Though they appear to be designed to be removed with a screwdriver, the way they're arranged makes it almost impossible to remove them with one.

Slide the entire headlight assembly forward a few inches so that you can reach the back of it.
<LI id=jsArticleStep5 itxtvisited="1">Step 5
Unscrew the plastic bulb socket assembly. This is the large, round component located right in the middle of the back of the main assembly. Turn it about a quarter turn to the left and you can pull it away from the main assembly. If you're replacing both the bulb and the main assembly, see the next section on how to replace the bulb, then resume this process.

Unplug all wiring harnesses from the back of the main assembly. Depending on your model year, there may be one, two or three wiring harnesses.
<LI id=jsArticleStep7 itxtvisited="1">Step 7
Pull the old assembly completely away from the car.
<LI id=jsArticleStep8 itxtvisited="1">Step 8
Slide the new assembly part of the way into place and reconnect all the wiring harnesses to the corresponding sockets on the back.
<LI id=jsArticleStep9 itxtvisited="1">Step 9
Insert the bulb socket assembly into the round hole on the back of the main assembly and turn it about a quarter turn to the right, locking it in place.
<LI id=jsArticleStep10 itxtvisited="1">Step 10
Push the assembly all the way into place.
<LI id=jsArticleStep11 itxtvisited="1">Step 11
Replace all three of the bolts that hold it in place. Screw each one down tightly with your adjustable wrench.
<LI id=jsArticleStep12 itxtvisited="1">Step 12
Replace the plastic cover if your ES300 has one. Push it straight down into place until you hear each of the plastic snaps make a clicking noise as they engage.

<LI id=jsArticleStep1 itxtvisited="1">Step 1
Complete steps 1 through 5 in section 1.
<LI id=jsArticleStep2 itxtvisited="1">Step 2
Put on a pair of gloves. Any type will work; just make sure that you can still work well with your hands.
<LI id=jsArticleStep3 itxtvisited="1">Step 3
Grab the old bulb by its socket and pull it straight out.
<LI id=jsArticleStep4 itxtvisited="1">Step 4
Hold the new bulb by its socket and push it straight down into the cavity on the socket assembly. It won't make an audible click when it's in place, so try to wiggle it or tug on it gently to make sure it's all the way in.
<LI id=jsArticleStep5 itxtvisited="1">Step 5
Reinsert the bulb socket assembly in the round hole on the back of the main assembly. Turn the socket assembly about one quarter turn to the right to lock it in place.
<LI id=jsArticleStep6 itxtvisited="1">Step 6
Complete steps 10 through 12 in section 1 to insert the headlight assembly back into place.
