I have a 2008 RX400h the daylight running lights are normally on when the engine is running. They are not at this time. I have checked the bulbs, they are fine. Can anyone please help? Thank you.

Thank you for the tip. I will do so.

Hello again, a quick update. I have done the obvious. Check the bulbs and fuses. The Daylight Running Light is still not coming on when the engine is on. Again, thank you for your assistance.

Thank you iMSQ. I went through the thread and am not able to resolve my issue. One post mentioned a replacement DRL. I believe this is an aftermarket modification, not sure. I was thinking of sorting it out with OEM parts.

Do your high beams work? Drl will not come on in park if car is started with parking brake on. Unless there is a blown fuse or bulb or the drl was disabled (requires Toyota software), they should come on. They used to work fine?

Thank you for your notes.
In response to your questions.
The high beams work.
The parking brake is off.
No blown fuse.
No blown bulb.
DRL was not disabled, it was working 2 weeks ago.
Again, thank you.
