My right low-beam burned out and I went to the dealer to have it replace. I was quoted a price of $419.00 . Love Lexus, but not that much! I looked at the bulb and it appeared easy to remove. I first unscrewed the circular plastic disc and then unscrewed the bulb connector. The bulb itself appears to be held in place by a thin wire with a small screw. This is where I need some help.
