I called Lexus of Tampa Bay and they were the ones who gave me the highest price (surprise, surprise) and also gave me the part number. I called a Toyota dealership and they said that that part number is Lexus only part number. Someone told me about guy on here named Jim Walker I believe, that sold the bulbs. I contacted him and he offered me a great deal, but his bulbs were for the 1st gen LS, and Lexus told me that the 2nd gen used different bulbs. After all that I looked around online some more and the cheapest I could find was something to the tone of $12 per bulb and I believe the A/C panel uses 7 or 8 bulbs. I can't find the part number, and the parts dept here is closed. On your side of the country a dealership should be open, you might be able to get a part number from them. Good luck, man.
