You know, if it's available on other Camrys then the mounting bracket might be there but no socket is installed. I had this happen on my Avalanche. Saves the manufacturer a couple of dollars on each vehicle. Look up under the dash above the footwell and see. If the bracket is there, the bulb and housing are probably universal and available at an auto parts store. I got the sockets and bulbs for mine at Autozone. I don't remember what I paid, but less than $5 probably. I then wired them to the dome light so they automatically came on when the door opened and then faded out when the door closed. If you're not handy, you might get it done at a radio installer at a more reasonable price. Hundreds of dollars is an extreme ripoff.
