E60 / E61 (2004 - 2010)
BMW 5-Series E60 Sedan was first seen in the Unites States in the fall of 2003 with a 2004 Model Year designation. The E61 wagon followed shortly there after. The E60/E61 5 series is now available as a 528i, 528xi, 535i, 535xi, 550i and a 535xi sports wagon! -- View the E60 Wiki

Here's a HID question

So, your HIDs are getting dim. Is it the lamps losing brightness, the ignitors getting weak (presumably if they light the ignitors are working) or is it the ballasts lowering output voltage. How would you know aside from shotgunning new parts into the car?

Learn HID technology. As the burner ages it requires higher operating voltage which shifts the output color spectrum out of the visible range. The HV supply ballast is under higher load. At the end the igniter may have to restrike frequently.

Burner life is about 2000 hours, about 200 hours/year at 50 MPH for 10,000 miles.. There are nine common types of burners, not all interchangeable.

Question was posted to glean knowledge, thanks.

This is a D1S lamp with integrated ignitor, external ballast. Light output appears bluish-white, I'd guess well over 5000K where OE is around 4300K, not pushing 7000K as there's no purple tinge. I've had the car over 7 years, so likely just the 'burner' needs renewing.

Lenses are clear but a bit pitted due to road rash, and cutoff is not sharp. Night driving is getting worse, especially with aging eyes. Maybe LED retro is in order here.

You likely just need new bulbs. Old bulbs, old ballasts.

Also, something everyone seems to be overlooking (in other current forum topics) is that different colour temperatures put out different amounts of useful light for the same wattage bulb. A 35w 6000k bluish tinted white light might look cool, but it's not ever going to look as bright as a 35w 4300k bulb. Personally, I like 5000-5500k. In general, the lower the colour temperature, the more useful output you'll get.

Very true. I'm way past trying to be 'cool' with blue lights. I'm going to try one new burner and see what I see.

OK, I fitted one new D1S lamp. Literal "night and day" difference.

Had to reset the beam height by quite a lot to bring it level to the passenger light (they were even with the old driver's lamp fitted). Wonder how many people re-aim lights after re-lamping...

Was wondering the same. Seems like all the bulbs come with the igniters though.

Where did you get the bulb? One of mine is now light violet so need to replace.

D1S has the ignitor integrated with the lamp. D2s have the lamp separate from the ignitor.

And when I had the assembly out of the car, I did notice a small spot on the wiring to the cornering lamp had insulation peeling off. Love BMWs...

Oh, and another give-back to the community: I did the headlight R&R without removing anything but the two top bolts and loosening the two lower slide bolts. At least for the LCI model, the lamp comes out without more than some wiggling, pushing rearward then popping the inner front edge forward. The wiring harness is on the rear, under the signal lamp socket. Maybe I'll shoot a couple pix when I do the other side next week.

FYI - When I replaced mine I found DS1 4300k lamps in Amazon for $20.00 - for the pair. I decided it was worth the gamble. That was a year ago. They looked identical to what I removed. They also had the D2's for the same price. Chinese, certainly. Work like originals tho.

^^ Much as I like saving money, I try not to buy stuff from China. Always exceptions, but try.

Most of the name brand stuff I found was made in China so I decided the extra $$ could be in my pocket.

^made in Hungary. Last I checked, not yet a part of China. If you can get a genuine name-brand part that's made in China, presumably it's made to the same standard as it might be elsewhere. The China parts I steer clear of: Xing Hing Qui light factory and such.

Received my $23 pair of DS1 6000k bulbs today from Amazon.

Happy New Year!!

Fun. But 4300K gives more effective light, so that's what I'll use.
