Both headlamps went out with 1 week of each other. replaced with sylvania h11 xenon bulbs as recommended by autozone website as compatible. installed both lights, verified they worked, drove approximately .5 miles to stop for lunch. turned off car and entered restaurant. approximately 5 minutes later, someone yelled a cars on fire. front of my car was engulfed in flames. fire department sawed hood off and distinguished flames. car was a total loss. lexus dealer service rep scolded me that i should never ut after market bulbs in their cars, to which i pointed out that maybe their manual should state such a fact. i believe there is some surge issue that caused both my headlamps to go out in the first place and that the sylvania bulbs ran hotter than the oem bulbs which triggered the fire. lexus will not share with me the pictures proving both bulbs were in stalled incorrectly and i have a hard time believing that since u have to insert and turn the bulbs - i would have seen if they weren't in correctly. the car has since been sold off but autozone came out and took the bulbs and wiring to their 'lab'. there's no other plausible reason for the fire other than the bulbs....
