Litronic Bi-Zenon Bulb Problem.

[JamesD]

Hi all,

The other day I noticed that one of the Litronic bi-zenon bulb's on the passenger side is shining more dull-yellower?

Strange because a while back I changed it? and the one on the drivers side is an older bulb but still shines brighter more white!

The bulb I use are: Phillips light Bulb H7 D2S Litronic

I've taking some pictures but it's more clearer in in person.

I actually noticed this while driving behind a car that the reflection of my left bulbs shine on the car in front looked more dull.

Are my bulbs on there last legs, do I need to replace them? (ouch it's like €120 for each bulb)

Or could it be a fuse issue?

Any ideas much appreciate

Thanks in advance as always guys

I think as the newer bulb ages it will get blueish in colour. It can't be a fuse as the light operates.

I would think the best solution is to replace HID bulbs in pairs. This would eliminate the visible difference in color.

I agree it is best to replace them at the same time, but did you double check to make sure that you bought the same temperature bulb? The colors of the lights change with the temp of the bulb.

Mine went dull yellow and started flickering for about a week. Then it died. There are some good deals on Ebay on the bulbs if you don't want the originals and they come with warranty. I'm still waiting for my pair. One website sent me the wrong ones, so I had to buy them elsewhere.

Did you check if that bulb is still under warranty?

There are some fake Philips bulbs out there too, so be aware. I would rather buy a no brand name bulb at a low price than a fake brand name that you still pay quite a bit for.

Can you swap the bulbs left and right and see if the problem follows the bulb? If it does, it's the bulb. If not, it's the ballast.

Good luck.

I think the color temperature should be 4300K
