2007 ES-350 Headlight Issue
 

I have a 2007 ES-350.

A few months ago, my passenger headlight went out. Flipping the headlight switch off and then back on would result in it lighting up again. This continued for a few days. After a few days, I was driving and both headlights went out and would not turn back on by simply switching the switch. When I parked, shut off the car, and started the car, the lights worked, but I had the right headlight still acting up.

I thought that perhaps the bulbs were going bad so I replaced them.

However, the driver headlight started acting up (shutting off randomly, but turning back on when I flipped the headlight switch). I thought that perhaps something was loose or not fully seated from when I installed the new bulbs so I reinstalled the driver bulb to confirm that it was installed properly.

Now, the driver light seems to be fine, but the passenger light is exhibiting the same symptoms that the driver light had encountered. To be clear, I did not swap the bulbs from passenger side to driver side, meaning that it is not just a bad bulb.

I am very confused as to why reinstalling the driver bulb seemed to fix the intermittent lighting issue on the driver side, but created an intermittent lighting issue on the passenger side.

Please help. Thanks!

reseat the pax bulb?

Do you have HIDs or halogen headlights?
