Has anyone replaced the low-beam bulb for a non-xenon?
I figured it out how to replace the low beam bulbs, and have done so. I'm at work now, but tonight I'll PM you again with info about how to do it. Also, I have some recommendations about replacement bulbs. I did a LOT of research, and would up picking
a set of Phillips Vision Plus bulbs that I ordered from the U.K. on the web from autolamps-online. Here's their URL:
http://www.autolamps-online.com/halogen/index.htm.
I'll also send you a URL to a site where they did very extensive tests of bulbs and chose the Vision Plus as best overall. Be careful with the "zenon look" blue bulbs; what you find out when you read everything is that they do NOT put out more light than the std bulb (in fact, they often put out LESS, because the coating on the bulb actually cuts out some light output). The Vision Plus bulbs are supposed to put out 50% more light than the std bulb, and they seem it to me. Also, they are NOT overwatted (they are the same 55w as the std bulb, and the same H7 size as the std bulbs), and they have a special treatment so they won't turn your clear light lenses yellow, as can happen with so many replacement bulbs. If you have to have bulbs with a somewhat "zenon" look, get the Phillips Blue Vision bulbs, which rate highly too. The bulbs that come std in MBs are Phillips bulbs, so you know you're getting something with as-new quality with the Phillips upgrades.
Note that the Vision Plus and the Blue Vision bulbs are NOT U.S. DOT approved (because of their higher output), so you cannot buy them in the U.S.
Finally, another HUGE improvement in my low beams came from simply adjusting the beams upwards. I'll tell you how to do this
too in my next PM.
I'll be back in touch tonight after I get home.
Cheers,
Bob
Thanks for the reply. I notice you sent me a PM but my PM box was full. If you could resend the PM that would be great.
I always use Phillips BlueVision or VisionPlus when "upgrading" my halogens and buy them from the same online store, Autolamps Online.
Thanks.
Arnee-

What I posted above is almost exactly what I sent you in my PM. When I found that your PM inbox was full, I just posted it on this forum instead.
Actually, what I'll do is post my info on this forum, rather than send it to you by PM. That way, anybody else who wants this info can have it too.
Oops.... I just remembered- my car is in the shop (some bozo hit me and took off my rear bumper), so I won't be able to take pics of where the low beam bulb is!!! I'll see what I can come up with tonight.....

The low beam bulbs are in the larger light housings which also contain the front turn signal blinker lights.
Open your hood, and look at the back of these light housings. You will see a rubbery-looking disc about 4" or 5" in diameter in the middle of each housing. These discs must be removed to get at the low beam bulbs.
To remove these discs, simply turn them counterclockwise (as you would unscrew a screw) about 1/8 turn or so until they hit a stop, and then simply lift them out. Look into the hole at the back of these housings which used to be covered by these discs, and you'll see the back of the low beam bulbs. To remove the bulbs, push them in slightly and turn them counterclockwise about 1/4 turn until they come loose. Then simply lift them out and disconnect them.
When you replace the rubber disc, be sure to turn it clockwise until you hear an audible "click" so that you will know it is locked back in place. If you don't turn it far enough to hear this click, it
probably isn't locked back in place and may come loose and fall
off.
Hope this helps!

OK, here are the directions for removing and replacing your W211 low beams (I'm having to do this by memory and without pics, 'cause my car is having body work done and isn't available for me to look at to refresh my memory with or to take pics of- but I should be able to "talk you through this" nonetheless):

it was a bit of a pain to get in there to change the lights since it's hard to fit your hands in there. and you need to be careful not to touch the bulb or else it will burn out faster.

Rock72 makes a great point that I should have mentioned: be sure to keep your fingerprint oils off of the new bulb! Leaving such on can and will cause the bulb to fail prematurely. This means either installing the new bulbs with gloves on (sheesh!),
or wiping down the installed bulb with a glass cleaner before
you button everything back up.

i did this. i got a set of philips blue lamps (don't remember exactly what they are called) but they have a bluish tint to make them look (sorta) like xenon lights.

Does the bluish tint degrade or improve your sight at night? Or is it about the same as the normal lights?
I'd like to do the same when I get my car as the blue tint will go well with my Tealite Blue colour. I don't know if this is allowed in Australia though...
I wouldn't do it if it has a negative impact on night driving vision. Your comment would be appreciated.
1. Real-world tests of various H7 bulbs (the same as that used for high and low beams in the non-zenon W211)- note the number of high-priced bulbs that failed miserably:
http://www.zx-12r.org/Motorcycle_inf...lbs%20Test.htm
2. Daniel Stern Lighting (part of the MBZ.Org website). This is a VERY informative website about auto lighting, blue-coated bulbs (bad), properly-made <clear> bulbs with a greater zenon mixture under higher pressure (good), true HID lighting (good), etc.
http://lighting.mbz.org/
Here's a great quote from the Daniel Stern piece:
The main thing is to keep in mind that the blue signal image of an HID headlamp is a throwaway byproduct of a light source that emits a great big lot of very nice white light, while the blue signal image of a blue-tinted halogen lamp is the meager blue ouput left when you've cut-out all the rest of the usable light.
Thanks for those links, there were really educational!
Assuming this guy is legit in his qualifications, I'm rethinking if I need the 'blue light'.
His recommendation for the VisionPlus lights have got me interested. Improved lighting and viewing distance is definitely better than improved looks

Just to confirm my understanding, are you saying that the standard W211 lights uses the Philip's Premium?

Am I right to say that I'll need to buy 4 of em, 2x low beam, 2x high beam?
VERY noticeably brighter. Not very expensive, really. I think it
cost $80 U.S. for all 4. And, yes, I replaced the high beams and the low beams both. They all use the same H7 bulbs. In conjunction with adjusting my low beams up a bit, my headlights are now a completely different ballgame from what they were stock! I used to dislike driving at night on low beams (and having to flick my high beams on periodically just to see what in the heck
was down the road), and now I can motor down the road on low beams only quite comfortably. Believe me, it's woth the $80!
When I ordered from Autolamps-online, they were running a special and gave me a third bulb for each pair I ordered, so now I have 2 replacement bulbs if I ever need them. Shipping was free too. Check it out:

My nav replacement has xenon (I added that as an option) so I'll see how big of a difference that is. I'm sure it will be *much* brighter.
Rock.
I may go for the Vision Plus bulbs.
I don't think chaning bulbs is illegal in Australia. They sell them at Repco/Autobarn and stuff. I think if they're really blue (like some of the numerous Lancers/WRXs/Civics etc), then perhaps they're illegal. Even the box says "For car-show purposes only".
The PIAA Plasma Whites I had on my S Class were ridiculous. They were supposed to be brighter, but in fact, made vision worse due to the blue hue. I assume they were not as good as the ones now. They were the first generation, non-yellow bulbs back then.
Gonna drop by the auto shop tomorrow to see if they have the VisionPlus. Do you intend to fit them yourself? I was just gonna get them and ask the dealer to fit them when my car arrives.
On hindsight I should have gotten the bi-xenons. Sometime in Nov I plan to drive to Melb, Atchuka, Wagga, Dubbo, Newcastle, Sydney, Canberra then back to Adelaide....visiting our branches and customers. That would rock up a few km's and there'll be plenty of night driving then. Those xenons sure would have come in handy in sighting them roo's!
I've replaced bulbs on my other cars before, so I may try to replace the bulbs myself. However, the car's in the shop right now for some electrical problems
. I'll take a look-see as soon as I get the car back.Sounds like you've got a big drive coming up- it'd be a great opportunity to run the car in with some nice, highway driving. Just be careful of the stone chips........oh and the roos!
