Replacing bulbs in Halogen Unit to Xenon or newer
Hi I apologize if this information is already out their, but after much searching I couldn't find a clear answer. I have a 2015 ML350 which I've had since new and the car has the base halogen headlamps. I have a X7 now and the headlights in that car are significantly better and it makes night time driving in the ML pale in comparison. I need some help as to whether I could just replace the halogen bulbs in my existing headlight unit to a xenon bulb or something newer or would that not be possible? I'm trying to keep this under $150 so buying new headlights aren't an option unless I could get some for under $200.

You can get the same conversion for the H7 halogen for around $50 or less. It’s probably your best option.

I would suggest to check out @AZN Optics They might have an option for you that you might like. I forget if it is xenon or something else.

Could you send a link, I would highly appreciate it. Also would it just be a simple unscrew bulb and insert new one or would additional work be needed like programming? The led bulb would fit in the halogen socket without issue right?

I think the xenon’s are 4800 and the LEDs are 6000 so the light it whiter.

This is the kit I bought. About $50 aud
The small fan kicks in as soon as the light turns on.
LED light after
Xenon light before
Comparing the two together the light output looks to be in the same position.
