Hella Xenon right bulb is dying. Any input will help lots!

1897 Views 13 Replies 6 Participants Last post by  JimB

I have a 2002 ML500 with Halogens. I switched them with aftermarket Hella Xenons in 2003. I guess they are the OEM Hella Xenons. Anyhow, the right bulb is now just starting to flicker. The color output is now blue-ish as compared to the left bulb, which is more white. It looks as though the bulb is dying.

What can I do to resolve this problem? I think I need to get a replacement bulb and that should fix it. Can anyone please point me to the right direction? Also, if I do need to replace the bulb, where can I get the replacement?

Any input is totally appreciated! Thank you in advance!

The HID bulbs have an average life of around 2,000 to 3,000+ hours. I had my BiXenon lamps first on my former 2001 ML 320 and then I installed them on my 2005 ML 500. I had one of the bulbs began to flicker and had to change it.

Though, the HID bulb on the other side is still working fine and may already have around 4,000+ hours. I always drive with my headlights on.

I bought the OEM HID Osram bulbs from the BMW dealer for $195.00.. Make sure you don't touch the bulb's quartz when you install them or it's life span may be shorter.

Funny thing is that the BiXenon assembly, the one that had the burnt HID bulb, is the same one that I had to reseal because it got all fog out and with large water condensation in it. The light beam became so scattered/diffused that the headlight will not iluminate the road correctly. The seal that joins the clear case and the black casing is poorly/cheaply sealed; it may be a common manufacturing defect..?. I put silicon around the seal of the lens and never again I had any case of fogging in that headlamp. I posted long time ago how I did that repair. I wonder if all that condensation/water causes a reduced bulb life.

There are some other owners that had some of the headlamp ventilation tubes fall down and they think that caused their fogging problems. In my case, it was a poor sealing around the lens/casing.
