I have a ES350 owners manual. It illustrates the bulb being pulled straight out of the socket. If you have the replacement bulb, you can see where best to grip bulb to remove.

Looks like a 194 type wedge lamp. Used in many cars.

That's like the bulbs that go in the interior light. Goes in most older dashes for the instrument panel, back light & gauges etc.
Normally, they go in both ways but will only work one way. There are little wires embedded into the glass that slips into the harness. The wires look basically the same, but will only work when inserted in the right direction. If it doesn't work one way, you turn it half around. So, make sure its in the right way & works before you install the harness/light back in the tail light assembly and put all the screws back in. Just insert the bulb & turn on the lights on (or activate the lights) and see if it works before reinstalling.

I welcome any corrections for any incorrect advice.

They should work in both directions.
That is a 194 lamp. There are several different wattages/brightness of that style lamp.

Relace with LEDs. Also, replace reverse lights with LEDs. Thank me later.
Keep in mind, unless you go and buy exactly OIEM bulb, you will end with little yellow car down in the dash with shining rear light warning. Lexus BCM does not like non OEM bulbs.
Ah, we own RX350, so I know.

Ukrbyk, what is OIEM? OP said he wants to change a defective bulb, not use a different part number. I doubt Lexus makes bulbs for its cars. My Lexus manual lists bulbs by function, bulb number, wattage and type, nothing about OEM. To date, I have not changed a bulb, so I don't know if the info in the Lexus manual is sufficient to get a replacement bulb at a car parts store with the same form, fit and function. I would hope so and not be at the mercy of a Lexus parts department.

The part number should be on the bulb.
If not the auto parts places can look it up.

It's hard to make a blanket statement to change everything to LED.
As U mentioned.... the on-board computers monitor bulb resistance which equates to wattage.
It is not easy to find an EXACT replacement LED bulb.
I have helped customers by measuring and supplying resistors to make LED's work.

My bad, my bad. OEM. Original Equipment Manufacturer. Lexus branded or used bulbs. Fat fingers and old age.. always punch several keys.
I replaced O-E-M reverse lights in out RX350 with LEDs, to much better visibility.

Thank you all.
PJmax was right about the type of bulb.

I figured out how to remove the bulb and hence updating the thread if someone else search for a similar question
The trick is to apply mild pressure at the base of the bulb. I used finger nails, you can use a plastic knife as well .

Updated picture shows where to apply pressure

I think you mean the edges on the bulb created where the bulb shape changes from a circle to a wedge. I doubt the base of the bulb is exposed. See image in post 3.
