Is the headlight bulb failing? D1S?

[tr4s]

The left headlight bulb has begun to exhibit a yellow hue, while the right bulb remains a bright white/blue tint.I have not previously owned a vehicle equipped with HIDs, but research indicates that this may signify impending failure. I require one. I believe it should be a D1S bulb. Do all individuals concur with this, and are certain options superior to others, or are they largely equivalent?

The light appears to be malfunctioning. Please examine this for fitting and related details. Additionally, a commendable company to engage with.

When I needed to replace mine on the W211, I purchased Osram.

Indeed, they are quite expensive!

Always substitute in pairs.

Valid observation

Consider Amazon, as they occasionally have promotions.

I attempted to replace a bulb in my W211 with a lesser-known brand to economise, but it resulted in flickering and ultimately failed to function.
Proceeding to Osram encountered no difficulties. I believe I ultimately procured them from Amazon.

I wanted to verify the model of the D1S bulb in my vehicle. The one currently malfunctioning is a Philips Zenstart, while the other side features an Osram Xenarc. It appears that matching is unnecessary, as I have not observed any differences in hue or performance among them. I believe I will choose for the Osram to complement the other one.
