Team-BHP - Comprehensive guide to LED Headlight upgrades

Hello Fellow Mates!

I am here as I seek help/advice while I am trying to upgrade my halogen bulbs for the 2015 MS Ciaz ZXi+. I have kept my car strictly stock and have been only using parts/pieces from the MS Service Center to date. But now, I feel that with the age and the car having completed its warranty period, I can now venture out to try new things and spice up things a little. While I have a few things in mind (ex. changing the interiors, alloys, etc), right off the bat I feel I need to upgrade my lights. I just sent my car for servicing as it had some issues, the brakes and a few more niggles needed some tending.

Before I sent it for servicing, I somehow felt that my halogen bulbs' visibility has reduced and I was finding it difficult to navigate myself in pitch-dark conditions as well. So I think this upgrade is more a of "NEED" than a want. And, hence I am here to seek and educate myself a little from your knowledge before I take the plunge.

I have been doing a little reading/browsing/watching on the internet and found that there are many LED bulbs that I can upgrade to like Nighteye (not a reliable brand it seems), Phillips (too costly but will go for it if its really worth it) and the most spoken about is Osram. So I am considering these Osrams, listing them all as I am not sure of which bulb holder fits my Ciaz lights and have asked my service advisor to share them so that I can order from Amazon.

-> Osram H4 46204CW LED Retrofit 12V (Pack of 2) - https://amzn.eu/d/fvcwzW1
-> Osram H7 45210CW Headlamp integrated driver (Set of 2,25W 12V) LED - https://amzn.eu/d/gVWTJLd
-> OSRAM H8/H11/ H16 46211CW Headlamp integrated driver (Set of 2, 25W 12V) - https://amzn.eu/d/c6Q6mYc

I want to understand if I am thinking in the right direction or am I missing something? Also, I have one critical aspect to think about before I make the upgrade. I intend to upgrade all the light (i.e. High/Low beam reflectors, Projector lamps, and Fogs lamps), and with the upgrade all the lights will be white. And, I live in Delhi so my thing is when winter comes and there is fog, will my visibility take a hit? My study and learning have told me YES, it will! So, should I let one set of lights remain a halogen one? If yes, which one? The logical choice will be the fog lamps, is this the right way to go? Because I see that the throw changes and is way better if I upgrade the fog lamps to also be LEDs.

Please feel free to share some light on anything additional that might be helpful for me while I am getting this done. My intention is to order these from Amazon and have the service center mechanics install them, usually, they don't but as my car has been visiting their center for the past 8 years they have agreed to help me out.

Thank you for your time and the help! Looking forward to your responses.

You need H7 bulbs for the main unit. Not sure about the type of fog light bulb, pls check manual. Since you need yellow lights during fog, suggest you upgrade fog lights to yellow projectors. Or you may keep current bulbs in main unit and only upgrade fog lights to white projectors so that you have one set of yellow lights.

Hello fellow BHPians,

The low beams on my 2022 Tata Nexon is highly inadequate.I have gone through this thread and Reinhards DIY for HIDs. While I considered trying the DIY approach, I'm concerned about potentially causing more harm than good. That's why I'm reaching out to the community for suggestions on reliable car accessories shops where I can explore options for a light upgrade.

Specifically, I'm considering upgrading to 42k LED lights for my low beam projector headlamps. My primary goal is to improve visibility without causing discomfort to oncoming traffic. Any recommendations or insights would be greatly appreciated. Thank you in advance for your assistance.

- Looking for something that doesn't hamper warranty or is more of an upgrade instead of a full change. I do not favor LED kits or HID cause most shops won't properly fit them, leaving headroom for dust and water to ingress the assembly. [Unless I'm wrong and there are kits that fit perfectly].

I think what would make sense for me would be perhaps a better set of halogen than stock. I noticed Phillips vs Osram but I couldn't decide for myself without a comparison.

- I want to stay within 4500k temp and I don't intend to blind traffic on the other side.
Also, is it worth upgrading the Fog Lamps ?

Upgrading the stock halogen bulbs in fog lamps to led will cause the light to scatter while hids should not be replaced in stock foglamp as it will affect the cornering function. HIds consume high power when they get ignited. The best bet is the solution provided by Reinhard. I spoke to blaze India, Amit quoted 5000 for a pair of 55 watt H7 Hids with 42k temperature with one year warranty. This will involve making holes in the dust caps, but they do provide rubber housing along with the HIds kit. some silicone sealant should do the trick. I am still contemplating if I should go for this Mod. I am someone who always sticks to the stock ones unless it's mandatory to upgrade. I have not dealt with blaze India before. Any idea how good they are and if they goof up with the specs I ordered or if I get a faulty product, do they take returns?

Hello guys. I need your help.

So my i20 sportz variant comes with reflector type halogens with a rating of H19 55/66 W.
The problem is that low beam is really poor. It's almost dangerous at times.
High beams are okay but nothing to write home about.

So my question is that is there anyway I can upgrade to a halogen projector setup? How much would that setup cost?

Or do I have the only choice of upgrading bulbs?
Also my car is in the warranty period so would that null my warranty? This is crucial because I've spent money on a 2 year extended warranty as well.

I know nothing about headlight upgrading so forgive me if I said anything stupid or ignorant.

Will test the performance next week during a planned roadtrip down south.

Can you please share the feedback of these? Also, is 75w + 75w (150w) the power output? How much watt they actually are to be fitted in 55/60w socket?

My concern is
1. Does this voids warranty?
2. Is there any risk for wiring damage which can lead to fire?
3. Will the socket/assembly withstand high heat dissipation?

Looking forward to your inputs.

Thanks!

150W Output is for the pair , but as discussed in this thread many times it might be misleading/inflated.

Does this voids warranty? - Yes , according to warranty terms any electric modification will void warranty but since its a plug and play setup you can swap the original bulbs in a minute and then visit service center for any warranty claims. In case of fire incident , investigators will obviously point to the headlight mod even if the root cause is something else.

Is there any risk for wiring damage which can lead to fire? - I don't think so , No modifications with the wiring setup.

Will the socket/assembly withstand high heat dissipation? - Thermal dissipation of LEDs is way less than that of Halogens even with lesser wattage , no issues there. (Refer Post #586 by Behemoth)

That said , I also have 100W Halogen pair (Excelite , same Korean brand as of stock bulb) , performnce of that bulb is absolutely amazing, No LED can beat that and costs fraction of what I paid for DHC LED. But Heat dissipation is a concern and hence not using it.
