2015 Mercedes C300
2015 C300 Light upgrade
I currently own a 2015 C300 with the regular halogen lights.
I really wanted to upgrade the headlights to Xeon Headlights with HID (which imho looks way more nicer). I checked with the dealership, they said they cannot do it (without providing me a reason as to why they won't).
Can the headlights be upgraded? or is it a limitation in the car that u cannot upgrade headlights (coz *i don't know* the Xeon lights may need more power or something?).
Also, upgrading the headlights should not affect the warranty right?
Any response is highly appreciated.
Thanks

HID requires a new system because the power requirements are different and needs a balast to manage the power requirement. Regular bulbs are like a candle compared to HID which is like a laser pointer.
You may find a kit for HID's but you'd have to buy entire new headlights and get them installed and wired, easily over $1000 for the change to HID.
Xenon by comparison is also a bulb like Halogen but the gasses are different. Xenon lasts longer, looks more whiter and is just a bit brighter with the same wattage, but it costs more, and it's still a bulb compared to HID which uses lenses to focus light created by an electric arc in a vacuum of metal vapor in a capsule.
There are HID kits for universal systems but would require modification to your headlights including cutting and such (depending on the kit), which could void your warranty.

Thanks RyanG for the information. The above information was highly useful.
Its unfortunate that Mercedes doesn't allow you to upgrade the lights.
But to your point about the Xenon Headlights (without the HID), I can still get those correct without voiding the warranty (since its the same wattage and all).

2015 C300 Light upgrade
Hello
greetings from Mauritius
It is difficult to upgrade your existing Halogen headlamp to Mercedes projector lens+ HID ones due to coding issues and headlamp harness differences.
What is easier to perform is a halogen to HID conversion, by using H7 HID bulbs made for reflector headlamps(bulbs are either for LHD or RHD) and Quick-start CANBUS ballasts rated at 35W.
IF you want more info you can send me a PM.

This!
Question? Can momentary on functions and keyless entry headlight on functions be disabled with command? This would need to be done for most HID conversions.

Has something changed recently that I'm not aware off? I think all the Morimoto retro kits still advise to disable the momentary on function for HID headlamps. Depending on the setup, sometimes the DRL need to be disabled unless that function can be routed to a LED emitter that also tricks the canbus.

Because that way they have something they can upcharge on packages. Most ridiculous they've done was offer folding rear seats as an upgrade option....

2015 C300 Light upgrade
OP asked about a way to upgrade the halogen headlamp, which comes without Xenon and LED strip. That's why i suggested the upgrade to HID bulbs.
AFAIK the momentary-on will not affect the working of the HID ballast(lifetime maybe) as the quick-start ones go to maximum brightness in about 6-8 seconds. I have HID on my fog lamps in my W204 and i have been using them for about a year now with no problem.
Even here in Mauritius i don't understand why Xenon+ Led wasn't given in the basic packages. We're also busy doing retrofits for front and rear camera in those cars. Cheap moves from MB

The momentary on is an issue with cheaper ballasts because with HID the ballast has to strike the arc which is a high voltage (burst) ignition sequence for the light to start working. Once the arc is stable the ballast adjusts voltage down as the light warms up. Basically, continual high discharge rates and cheap capacitors or components don't go well in the long run. It'll work for a while and then die. You can get quality digital ballasts which are suited for momentary on/off (e.g. those suited for high beams) but even there it's difficult to know unless you have reviews or recommendations.
Have a look at retro fit LED instead of HID kits. They use the same principle (i.e. replacement bulb which is suited to fit the socket of choice), but their electronics are completely different and much better suited to short on/off bursts. The LED kits can however cause you other issues - especially on CANbus systems which are designed to monitor the load of things like your lighting for example.

I've retrofitted LEDs on other vehicles with reflector housings as fog lights. They will not work well for retrofitting the main headlamps in a reflector housing. The housing would need to be replaced with a projector style. I haven't seen any aftermarket LEDs yet that can compete with a good HID setup. The factory intelligent LEDs on my car are amazing but all the aftermarket LEDs I've seen are not even in the same league.

All true. The lights need to be projector based. Even if you're ignoring the illegality of doing so, using HID or LED on a basic reflector style light is not only a danger, but a bloody nuisance to other road users.

Led bulbs nowadays come with certifications such as DOT, Emark, Rohs and CE.
Cut-offs are similar to halogens, as bright as HIDs and glare-free.
If you'd like a pair we'd be glad to have them shipped to you. Shipping fee applies.
