Hey guys, I was wondering if anyone can tell me what is a good brand of HID bulbs? I have the P2 w/c is 4300k stock HID and I want to change it to 6000k. Is it hard to replace them or should I take it to the dealer and have them do it? Also, is there a DIY on how to replace the high beam bulbs? Thanks!

 

Please do use the search function. This topic has just been covered ...

 

Or one can finally open up the owner's manual and read it.

 

If everyone did that, there wouldn't be reason to have an MB forum . .

 

My owner's manual does not show alternatives to the factory installed bulbs as you suggest in your post.

 

I tried looking at the manual, it didn't have any instructions on how to change the HID bulb nor change the high beam. I was expecting replies like... the philips bulb is good, the apexcone, sylvania, etc. Anyway, thanks for all the replies and I guess I'll do more searching, rather than posting questions.

 

OEM brands are OSRAMS and Philips, our C used OSRAMS. Changing bulbs is definitely a DIY, here a pic showing how it looks on how to remove the bulb, it just two metal clips holding the bulbs.

Thanks a lot, I really appreciate it!

 

This forum is my owners manual

 

 

Apexcone brand is definitely cheapest and most reliable as far as I could tell you. LIFETIME warranty as well.

 

we are fully stocked with all HID bulbs, stock xenons are rated at 4300k, here is a side by side shot

Which is stock?

The left shuld be the stock one. But as color shifting involves, eventually OEM bulbs will looks blue too. Just might take a couple of years, hehehe.

 

with D2S (most widely used design), Osrams tend to be a scootch 'mellower'
in hue than the Phillips. natch, devil in the details as there are many models,
lot numbers, etc. here is something from my notes on Phillips D2S bulbs.

 

Raymond any idea on why MB uses Osrams instead of Philips? I have also question myself of this because my other two cars with hid uses Philips D2S which were Honda's.

no idea if factual or not (or part).

Osram/Sylvania is Germany/USA, vs Philips is Netherlands.

dont know if NAmerican models differ from Euro, etc etc. so anything in my
pea brain would simply be speculative

 

i was comparing the two, philips and osram, the philips D1S bulb are a lot heaver than the osrams. I read an independent article somewhere on the net about retrofitting, and the guys said, mano to mano, he think the philips are a bit brighter and bluer. You guys think the philps are brighter than the osram? Or it something that is not even noticeable.

 

charlie -
i think if you A<>B them, you can tell slight difference. but in the end, they're
not really noticeable on the road. bear in mind that color balance between
two competitive bulbs may appear to be brighter, but eyeball isn't the best
measure of lumens when separated by couple hundred ēK.

i dont think it's worth quibbling over because 1) lumens, vs color rendition,
vs comfort, etc is one thing; 2) when so many bulb designs are available,
is it really worth arguing one model/lot # is better than another?; 3) D1S
have integral igniters, don't they?....so weighing the 'bulb' really isn't
realistic, i.e. the weight difference is in the electronics within the box.

 

Yes the D1S are bulit with integral igniters, comparing with both igniter boxes and holding them both in each hands, the philips are noticeable heavier than the osram. Just wondering that is all since you are quite knowledgable in this field
