I've got a Lexus RX 350 2012 and not sure what to do because the passenger headlight turns off after the car runs for a couple of minutes. On the passenger side the regular light works for a short bit, the high beams work all the time and the turn signal also works, but the rest of the lights don't work (not sure what they are exactly called). On the driver side, all the lights work as expected. Thoughts on what I should check?

See this then tell us if you have halogen or HID headlights. It makes a difference in attempting a diagnosis.

The links to the vehicles in that thread don't work, but here is a video of my car: https://streamable.com/yj3b6y

 

You have HIDs. It’s going bad. Time to replace.

 

Ok. So that's normal behavior? I don't have to worry about anything worse?

 

HID bulb lasts about 2,000 hours. Could also be the ballast but given the age of your car replace the bulb first.

 

Thank you. Any recommendations on bulbs?

 

These are highly regarded

It might not match exactly the colour temperature of your other bulb (or brightness), a new Lexus original might not either not a bad idea to replace them in pairs.

 

I agree, you should replace both bulbs as they do get dimmer over time and miles. Your other bulb is certainly going to be dimmer than a new bulb and may also soon fail.

 

Thank you! I ordered these a couple days and installed them tonight and they worked great! I think my problem is solved as they didn't turn off at all.

 

I did exactly that and it seems to be working great! Thank you so much for your help.

 

Well done.
