you dont you get a new car
If you grab the light and pull it straight twards yourself it will come off. The bulb is in there
I recently had to replace the trunk light in my '97 ES300. If you just need the bulb, it's NOT replacement #194 that Walmart, Advanced Auto and others list. You need a 12V, 3 Watt bulb that looks like a fuse. I finally had to buy mine from our local Lexus dealer. Pop open the light cover with a screwdriver and carefully pull out the bulb. Try this first because it's probably only the bulb that is bad.
To change brake light bulbs on a 1998 Lexus ES300, open the trunk lid. Locate the plastic rivet on the side of the trunk liner. Turn the rivet while pushing in with a screwdriver. Remove the rivet and the trunk liner can be pulled away to access the bulb. Push in and turn the bulb to remove. Insert the new bulb the same way. Replace the rivet in the trunk liner.
If I remember correctly, there is a rubber cover on the back side of the headlight assembly (under the hood). Once that is pulled back, there is a a wire clip that holds the bulb in place. Once the wire clip is dis-engaged, the bulb will slide out of the socket/holder.
Along the rear of the inside of the trunk there are four small bolts which need to be removed. Once removed, you will be able to push out the outer plastic cover holdind the light bulbs and wiring. From there, you can easily remove and replace the bulbs.
