I have a 2001 RX300 and found out it is very easy to change the headlights. From the back, remove the plastic clip holding the wires and bulb casing. Then turn the bulb casing 1/8th turn and remove. The new products have you replace the small plastic casing and bulb in a single unit for about $10. No Tools needed.
