I have a 2007 is250...having a headlight issue, I have

Greetings, my name is...

Greetings, my name is ***** ***** I have a 2007 is250...having a headlight issue, I have replaced both HID low beam bulbs and yet lights still wont come on! I don't have a lot of money to diagnose exactly what is wrong. I saw something about the headlight relay perhaps being bad, could replacing that perhaps end this mystery? Much thanks, *****: Have you checked the fuses? Have you checked the bulbs?

Hi Pearl, yes have checked fuses and just replaced the bulbs.

Mechanic's Assistant: What is the model of your '07 Lexus?

IS250

Mechanic's Assistant: Are you fixing your vehicle yourself? What have you tried so far?

Working on it with a friend that is a mechanic, we replaced the bulbs so far, wondering if it could be the headlight relay

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

No, I think that should be it, thank you!

Hello. Welcome to Just Answer. Please allow me to assist you. I would doubt highly that the relay is the issue. Please describe the issue that was occurring that caused you to replace the bulbs. Did they illuminate then go back out after a few seconds?

Well it's a 2007, I have had the car for roughly 2-1/2 years so I attribute the bulbs going out just to age of the vehicle. When the bulbs were replaced, they never came on at all...still nothing when I activate the lights.
Phone call session started

Check for power in the H-LP R/LWR and the H-LP L/LWR. If you have power in these fuses the relay is OK. Check for power at the ballast in the Red with a Black stripe wire (Driver side) and power to the Red with a Green stripe wire (passenger side). If you have power in both wires I suspect faulty ballasts. Thanks for choosing Just Answer.
