Started my car up over at my buddy's place last night to take a little drive and thought I was hallucinating for a moment. My passenger side headlight beam was bobbing up and down a bit all by itself. I was parked facing a white picket fence maybe about 5 feet away and could see a fluctuation of 1 1/2" up and down. I move the adjustment wheel for the headlights down one notch and up again and the light stopped moving. Shut the car down to go into the store started it back up and when I got back to my buddy's place it was doing it again. Being the highly trained technical individual that I am I just gave the headlight a light smack with the base of my hand and it quit. I'm willing to bet that it will act up again. Will see in a few hours when the sun goes down. Anyone else ever have a problem like this?

 

I haven't noticed anything like that, but I will keep my eye open now. hopefully the good ole smack-a-roo will do the trick

 

lol, yeah let me know if you notice this on your car ever, should have seen the look on my buddy's face when he saw me give my evo a smack, didn't hit hard at all but he looked as though he wanted to cry

 

You are not alone my friend...I adjusted my headlights pointing them higher, and now they bob up and down sometimes...but it rarely happens when I just start up the car...they usually start going crazy when I adjust them using the switch. They stop after a couple seconds so I dont worry about it.

 

Raising this thread from the dead, but my car is doing this also. It only does it on the passenger side, and at the lowest two settings. I did the manual adjustment to the headlight mod a year and a half ago, and am wondering if this is a side effect, or maybe if something is going bad (like the motor that adjusts the headlights).

Any thoughts?

 

This has been happening to me for a while as well. The passenger side is usually the offender, but the driver side does this from time to time as well. This only happens on the highest setting. If I bring it down a notch, it does not bob anymore. FYI, I also adjusted my headlights up from the highest setting, since they were aimming a bit low. It could be a side effect?

 

try it with the engine off and the lights on. Is it a free style bob, or can you hear the headlight adjusting motor humming away, trying to adjust? If it's the latter, mine do it to. The passanger side will do this when I adjust the lights up/down, it takes about 3 corrections before it's happy and stops. But you can hear the headlight motor making the light "bob".

If it's more a freestyle bob, like one of those dogs you put on your dash with the bobbing head, well that's something different.

 

My passenger side headlight does the same thing as well. Only when I adjust the headlights though.

 

Both of mine do this all the time when starting the car and randomly. I turned the lights up manually so they aim higher now, dunno if that has to do with it.

 

Mine has done it once before. I turned them down one notch and they stopped and haven't repeated. I wonder if it has to do with the last UP position contacts..?

My "band-aid solution" is manually aiming the lights up so that they are where I want them when the switch is in the middle.

 

Yes, I've tried it with my engine off. The headlight motor is running like it's trying to constantly adjust itself, or like I'm moving the adjustment manually up and down. It does this constantly even when I'm driving and does not stop, unless I bring it down a notch on the adjuster. I wonder if I need to go adjust the aim of my headlights, on the top settting, back to stock levels... maybe it'll stop the motor from trying to auto adjust...

 

Can you believe mine still does this?

 

Must be an EVo 8 problem my IX dosen't do this.

 

Mine as well. I've given up on trying to fix it.

 

There was a thread on hear a while ago about the samething. The guy ended up taking the car to the dealership and they replaced the headlamp assembly... from what he said his problem was fixed
