Any fixes to this? I've tried replacing the bulbs twice with osram and a cheap Chinese one. The light on the road is still dim. I hate that a car following me also casts a shadow infront of me because the headlights are so dim.

 

Model year and mileage? Have you had the ballasts inspected? They may be your issue. Also how clear at the lenses? You can get replacement ballasts at Rock Auto

08 with 105k miles. Lenses are almost clear with a slight yellow.

 

It is time to use a headlight lens restoration kit. There are several on Amazon. I liked the 3M ones then finished with Mequires headlight coating spray for UV protection that lasts a year

Cerakote is also another good one, used it on mine, 2 years and no problems so far.

 

Also check your alternator output voltage.

 

Clutchless, hate to highjack but any idea where the ballast is located? My passenger light changed color for about a week or two then went out for good.

Thanks.

2. Replacing the ballast is a lot of work, especially if it may not be the problem. Since both are dim, I suspect something else. I doubt both ballasts would fail at the same time and when they do fail it appears to stop the lights from working, not make them dim. When they are dim it appears to be due to improper seating of the bulbs during installation, or bad bulbs.

See if you can run diagnostics on the lighting module to see if it has any fault codes associated with the switch or circuit. Or take it to a shop for further diagnostics before throwing more random parts and money away without knowing the real problem. You can find a used ballast on eBay or http://www.rancholexusrecycling.com/

3. Did you follow this procedure when replacing your bulbs:

If you immediately turn your headlights off and back on does the passenger light come back on? If so, you have a bad bulb. It's easy to replace yourself. The part will set you back $240 though (OEM through the dealer).

1. Remove the plastic HID socket cover by turning it counter-clockwise.

2. Remove the silver metal socket fitting attached to the braided cable by turning counter-clockwise about 45 degrees and pulling towards you.

3. There's a U-shaped set spring retainer that has kind of curled circle ends. This holds the bulb assembly in place by locking into notches on either side at roughly 11:00 & 1:00 on the housing. Pinch those two curled ends towards each other and pull them out and down to clear the notches and swing the retainer downward. This will release the bulb in the very center of the unit.

4. Pull the bulb out by it's base. It's about 3" long and comes straight out. Don't touch the glass if you intend to reuse the bulb.

5. The Toyota HID bulb is part # 90981-20024 (for my 2007 ES350).

6. Holding the new bulb by the base and without touching the glass, push the bulb back into the hole. There are notches & tabs in the base and mount that must match. Just rotate the bulb until it catches.

7. Reset the retaining spring by swinging it up and pushing it in while pinching the curled ends a bit. Release the ends when they lock into the metal notches on the housing. Make sure the retainer is secure before proceeding.

8. Reattach the metal socket fitting by pushing in at and turning clockwise 45 degrees from roughly a 10:00 to a 12:00 position.

9. Reattach the plastic cover by turning it clockwise.
