How to remove headlight assembly on 2003 Lexus GX470
You are going to have to replace the entire Headlamp Assembly, very expensive.
If its the front turn signal you open your hood and partly remove the black plastic cover on top of your headlights. Then you should see a screw on that screws on your signal light. Remove the screw and take off the the signal light and then remove the bulb.
I don't know about 95, but on the 94, you have to take out the whole light assembly from the front. Take off the cover inside the hood from the top, expose the headlight bolts, remove the headlight. Good lucK!
Remove the retaining screws from the headlight assembly. Remove the wiring harness from the back of the headlight. The headlight will come out. Reverse the process to install the new headlight.
A lot.
You need to remove the side marker first. Remove the screw and pull hard perpendicular to the car to remove the side marker. Once that's removed you can see 2 screws on bottom of the headlight/foglight assembly and one screw on the top of the assembly as well as one nut on the side of the light assembly. Remove those screws and nut and you can pull out the whole headlight/foglight assembly. Remove the connector by pulling it straight out. Remove the rubber gasket and the spring lock. Assembly is the opposite.

The bulbs go in from the rear. You may have to remove the light asy, by removing the top plastic rivet and sliding the whole assembly toward the front to disengage the three plastic assembly tabs.
You can find the thermostat on a 1995 Lexus GS300 near the radiator. To locate it, remove the upper hose assembly where it hooks to the radiator.
If you look straight up inside the bumper you will see the plug that holds the bulb just twist and it will come outFOR 99' ES300 MODELS: You do not have to do the things mentioned above. The process is much easier and simpler. No need to even open the hood. All you have to do is pull the whole turn signal assembly forward. NOTE: It is important that you do NOT pull it sideways or even at an angle for it might break the plastic clip. There is only one clip holding the assembly from the frame. To start, use a screw driver or similar and insert it in the farthest part of the signal light assembly from the front. Pry gently to move the assembly forward about an inch or two to completely unlatch the plastic clip that is holding it in place. This clip is located in the middle of the assembly. Then remove the assembly still attached by the wires. Twist the lamp holder out of it's socket to replace the busted light.Read more: How_do_you_remove_front_lamp_assembly_on_a_Lexus_ES300-98_to_replace_turn_signal_bulb
