From previous forums, people are having problems with their auto leveling headlights after installing their d2r bulbs. Why is that? Is there a correct way to install the d2r bulbs ? Does disconnecting the battery better or disconnecting the ballast better to do it the correct way ? I'm going to install new 5000k soon. I would appreciate your support. Thank you.

 

I never disconnected anything when I changed mine. Just opened up the cap, unplugged and switched the bulbs. I've never had any problems.

I remember seeing one post about auto-leveling problems recently, are there more similar incidents after changing bulbs?

 

I Got the same issue i replace both of my headlights with new one and both bulbs and after the replacement the driver side headlight doesn't level i will pull my bumper tomorrow and change the motor leveling and see what happen cause i have a spare leveler from my old headlights i will let you guys know.

 

because they don't know what they are doing and they messed something up! i just did mine and had NO problem with my auto levelers working afterwards

 

Never thought changing a bulb would be so complicated. Other than the lack of space behind the headlight, there should be no problem.

 

me either. and omfg u right bout lack of space!


i didnt even disconnect my battery i just didnt have keys in....mine still work fine

 

Sounds more like you got a light with a bad motor or the auto-leveler didn't get plugged in than a problem caused by changing bulbs. I still don't understand how it could get messed up changing bulbs.

You guys are right about no space behind the lights. One of those times I wish I had small hands, it took me 10 minutes to get one of the grey caps back on because of the lack of space!

 

Thank you guys for responding. Should i disconnect the batter when i replace my d2r bulbs ? I hear people saying to disconnect the ballast then installing the bulbs.

 

If you really want to you can. I always just make sure the headlights are off. If you turn on the headlights without a bulb inside, the ballast could give you a nice shock.

 

what can i mess up just by changing the bulb,so what you're saying is that all the guys that replace their bulbs, their headlights and the levelers are not working proprely afterwards don't know what they are doing i am not new to this changing bulb stuff.I am offended by what u said

 

um u can mess up your auto levelers apparently. i changed my bulbs and NOTHING messed up. sorry if your offended, wasn't my intentions but facts are facts. leveler was fine till YOU changed the bulb right?

 

Ok look my headlights are brand new they already came with bulbs inside ,all i did was transfer the ballast and stuff .Then the driver side wouldn't level but i will find out this sunday and will let you guys know cause i am removing the whole front end,and replace levelling motor under the headlight i think that what the problem is .

 

I didn't realize how complicate this would be...it just simply plug and play...no need to disconnect anything rather than turn off the headlight...space is something you need to work on..cuz there is any space....

 

Hmm... Might be because some people got big hands and accidentally hit the headlight housing too many times and the adjusting screws got loose and moved the whole headlight unit ????
