Can anyone tell me what purpose does the headlamp washers on my 07 RX350 provide. Just don't make sense to me. Just squirting washer fluid on headlights.

 

You know how sometimes when you're driving on the highway in the winter, dirt/muddy water gets kicked up onto the windshield and you have to run the windshield washer to clean it? Well that same material collects on the headlights, and the more the buildup, the less effective the headlights.

Years ago when I lived in upstate NY, I was on a rural highway following a number of cars, after a while I started to realize that my headlights were dim. I pulled over to the side of the road and found that the lights were completely covered with grime. I had to get some snow from the side of the road and clean them off, and it made a huge difference.

I like the headlight washers; you don't realize their effectiveness, which is the point, because you would realize the alternative.

 

They're great for bugs too - the fluid squirts out at high pressure.

Such high pressure in fact, that the cheapest replacement pump I could find when mine crapped out was online for $130 US. If the solenoid that runs the pump goes, it's in the $200 range. If the pop up jets in the bumper go, they're around $200 (or maybe more - I forget) as well.

Still, they look cool when they're spraying.

 

I've also heard that when HID housings get dirty they can blind oncoming vehicles because of light deflection so it would help in that regard also. You don't go mudbogging in yours

 

Here in western PA, I use the washers almost every time it snows and I am driving. I think that they work well at removing mild build ups of slush. I don't know about bugs but then I wash my car frequently enough that this isn't a problem.

 

Can some one tell me how to make them work? I just noticed I have them on my 2005 RX330 but my neighbors does not. I see the button for it on my dash near the heated seat controls. Press it nothing happens hahaha. Not sure what I am supposed to do? Does my car need to be in drive?

 

Well, in Europe washers are REQUIRED if car is equipped with HID lights. Not sure about USA

 

The headlights have to be on for them to work. Use the button or turn on your windshield wipers and activate the wiper fluid.

 

K will try it. I just wanna see if it works lol!

 

has anyone removed the bumper? my passenger side front bumper was sagging so i took the bumper out and put it back and when i was removing it i disconnected the washer plug and made sure i plugged it back and now headlight washer doesn't work. i did have my headlights on and tried windshield washer as well but still not getting anything from headlight washer... anyone have suggestions?

thanks

 

I think these should be on every Lexus model

 

I don't think mine works. Lights on, press button while wipers are rolling. I even used the spray. But the car was in park I think.

 

Try pulling the wiper stalk towards you to activate the windshield washer fluid with the headlights on. As far as the button, it should work when pushed with the headlights on. Being in park doesn't matter. Do you have enough washer fluid in there?

 

In where? Is there a separate storage for those? it's totally ridiculous to have to pull back the stalk AND push the button. I don't have two right hands. lol if it is the design is bonkers.

I tried it tonight while I was driving but forgot to check if it worked or not when I got home heh.

 

Washer fluid reservoir is for both windshield and headlamp washers. You don't have to pull the stalk and press the button. Both activate it independently. Did you notice the headlights dimming when you tried it? The fluid obscures the light a bit.
