Out of warranty and had the same problem with bulb went out however I managed to have Lexus replaced both headlight at no cost ($3,650.00)!. I bought the very expensive bulb $165.00 at a dealer but still it didn't work so I went further and found out water made it inside the "Ballast" and damaged it. The Culprit is a bad rubber seal on the Ballast chamber and bad location of the ballast which was very susceptible to water splashing during heavy rain and pool of water on streets conditions.
