| DIY: LED headlamps upgrade for stock halogen projectors (Hyundai i20) Greetings, this is my first thread on Teambhp! I created it because I could find a lot of info on putting LEDs inside normal halogen reflector housings, but barely anything about projector housings made for halogens. Searching for "LED projector upgrade" on google gives you anything from video projectors to aftermarket projector kits which come with an LED already attached to it. My car came with projector headlamps from the factory but with halogen bulbs used. Most youtubers seemed to be modifying the base/mid model which had reflector headlamps. So I did some research, combed through foreign articles and videos and sifted some meaningful info from the misleading, written only to sell you something or hit a word limit on a blogpost / create a video long enough to get money on youtube ads. I finally ended up with a satisfactory upgrade a year ago. I will share everything I learnt here. So starting with some basics: The car:![]() My 2016 Hyundai i20 asta (o) It has projector headlamps with a halogen bulb and a shutter that moves for high beam or low beam. The single bulb acts as both high beam and low beam. Also included on either side are halogen cornering lamps that turn on when the steering is turned more than a specified angle. They are a boon when taking corners on unfamiliar Indian roads with no streetlamps, where the area right outside your main headlamps' field of vision might hide a rock, a cliff or a sleeping cow. The main headlamps too worked decently but I was always itching for an upgrade, both in terms of colour and light output. The lights felt decent when there were no other cars around but feeble and lacking in traffic, especially when there was a vehicle coming head on. Most people also didn't respect you flashing your lights to dip their headlamps. The options available in the market: |

| re: DIY: LED headlamps upgrade for stock halogen projectors (Hyundai i20) Nice Post brother. I went through a similar ordeal almost a month back where i replaced the stock Halogens in my Creta with Osram 35Watt LEDs.I did not have a happy ending but i wish yours a long lasting one.Your post gave me another ray of hope however I have a few questions and would appreciate your response:- 1. Can you share the Link from where did you purchase this? 2. I am assuming there was no need to cut the cap cover to accommodate the LED assembly.Right? 3.Can you perform a small test for me to check if your setup also exhibits the same behavior as mine which according to an expert means that the LED are not getting enough power.What I am trying to ascertain if this behavior is same across all LED or mine was faulty unit.Ill explain the test at the end . 4.The members on the forum believe the higher the wattage the more heat it will generate and without sufficient ventilation it might lead to the melting/blackening of the reflectors or the LED holder itself. Your thoughts? 5. How long have you been using this setup and whats the warranty offered on this setup? 6.Roughly how many feet is the throw of the light? 7.What is the longest duration(In Hours) have you used them in a stretch and if you faced any issues? The Test:- Park your vehicle in front of a wall with roughly 4 foot distance between both. Switch on the LED and after a minute observe the following closely:- 1. Slight flicker in the throw on the wall. You need to be very close to the wall to observe it.Since the flicker is very minute you have to be really focused.Its like a shorter version of voltage fluctuation when it occurs at our homes. In my case there was a faint flicker which was caught by the guy who did the light adjustment on my vehicle.Apparently I returned the Osram LED set as i got suspicious if they were faulty .If yours also exhibits the same behavior then either yours is also faulty(based upon the logic given to me) OR its a expected behavior and nothing to worry about. I am not trying to discourage you instead just trying to look for similarities/difference in your setup and mine. Here is my post just in case you want to go through the whole story. https://www.team-bhp.com/forum/showt...errerid=574755 (Review | Osram LEDriving HL Premium | 6000 Kelvin | Hyundai Creta) |

1. I bought it from autobahn on amazon : https://www.amazon.in/gp/product/B08...?ie=UTF8&psc=1 It seems to be out of stock on amazon sadly. It is available on their website https://autobahntechnologies.com/pro...eadlight-bulb/ You can also buy it directly from China on aliexpress : https://www.aliexpress.com/item/4001282544181.html Do note that you might face issues with customs or shipping. Might have to use a forwarding address. 2. I did not modify the dust cap in any way. I bought some bigger caps from amazon but it was not fitting as tight due to being cheaply made. So I decided to just risk it with the stock dust caps and it has been fine so far 3. Sure 4. They are correct when it comes to halogens, however : Quote:
LEDs consume much less power than Halogen and also produce much less heat comparably so I doubt you could damage the headlight assembly which was built to withstand halogen temperatures. This is assuming that these are modern, good quality LEDs and not factory rejects / defective pieces which are being sold by shady shops instead of being disposed off. The LED itself will have a shorter life due to lack of proper ventilation + it will throttle itself to be less bright to lower temperature. I haven't seen any noticeable decrease over time as it heats up though. Try to improve ventilation if you can but protecting them from dust and moisture is priority no 1. 5. I have been using this since last december so almost a year now. Warranty offered is 2 years. If it conks out before then, I will get it replaced and update this thread. 6. I am not sure. But it is enough to light up a decent enough range. I am a bit busy due to Onam here in Kerala but I have uploaded an old video of driving in the rain to help you judge it : 7. Around 6 hours continuously I think from when I was returning back from a hill station trip at night. 0 issues faced other than being nauseous from all the hair pin turns. 8. The test : I see no issues but I think I understand what you mean. LEDs are not continous, they have a refresh rate so they turn on and off extremely quickly. This is not visible to the naked eye nor is it noticeable and if it is, then that means your LED driver or your chip is about to fail. My father's landcruiser had a similar problem a while after we replaced the foglamps with LEDs. The stock HID headlamps by themselves were more than good enough so this was purely a cosmetic upgrade to make the foglamps match the colour. ![]() Stock setup We didn't have much knowledge about this at the time so we just took it to a shop and asked them to match the colour and install it. They used some brand I don't remember but the result was good from an aesthetics POV. Anyway, about a year or two, it started to show a mild flickering on just one side that progressively got worse over the months until the one of the two led chips inside the foglamp died. Now the left hand side foglamp was noticeably dimmer than the right hand side one. Couldn't be bothered to remove the bumper to reinstall the one ones so we just kept them turned off because we never really needed them anyway. ![]() After the upgrade and before one of the foglamps conked off. It looked pretty good with all white lights. | ||

| Re: DIY: LED headlamps upgrade for stock halogen projectors (Hyundai i20) I had done a similar LED upgrade a month back in my 2017 Hyundai Verna. My stock halogen setup was decent but i was planning a trip from Chennai to Pune and was looking for some better lighting for travelling in the highways. So I went to my trusted detailing shop and enquired on the LED upgrade. I didn't have much idea on the brand and the model to be upgraded. But he gets lot of high-end cars for audio / light / interior upgrades. So I went with his suggestion. Philips Ultinon Pro9000 HL (Costed Rs.10500) for the main headlight. Aazoom AZ1301 (Costed Rs.8000) for the fog light But I was not really happy with the performance. It was fine when I saw the brightness from outside the car. But when driving, especially in the highways, I felt the stock setup with halogen was much better. And it sucked in the rains. I came from Pune to Chennai a week back and I even wondered if the lights worked. And its perfectly fine inside the city. I think it was really not a worthy upgrade for Rs.18,500. ![]() ![]() ![]() Low Beam ![]() High Beam ![]() |

https://www.bulbfacts.com/led-kits/chart/ Here is a handy chart that rates a lot of LEDs on both projector and reflectors. I couldn't actually find most of them in our domestic markets though so I didn't link it in the original post. https://www.team-bhp.com/forum/modif...led-bulbs.html (Upgrading to the Ultinon Pro 9000 LED Bulbs) Here is a post from a fellow teambhp member who used the same bulbs in a polo's reflector headlamps. You might find it useful. | |

My understanding is Verna comes with HB3 bulb type as the main headlight bulb so asking. | |

This thread perhaps makes me want to revisit the idea of replacing the HLGNs on my Figo to a better solid, cost effective LED. My primary dilemma was with the longevity of the LEDs. The Aliexpress one currently doing duty on my motorcycle -- the unit themselves are pretty robust, lo I've started to experience where one of the LEDs (HB in my case) started to flicker and give up the ghost or work intermittently, all after a few months of ownership, a shame indeed at night. I'd have loved, if you could have thrown in some images of actual driver unit, wiring harness and the bulb itself, which would have satiated my OCD. But do quote me next time for your detailed post update, which I'd love to hear. Cheers! VJ | |

| Re: DIY: LED headlamps upgrade for stock halogen projectors (Hyundai i20) Well explained buddy. I experimented on a similar note for my Creta (2019) model. This was referred to me by my friend who also owns his own workshop and due to my frequent night travels he suggested this Power Vision V60 and PVMAX Led Conversion Kit. (Cost me 14000 INR including installation) ![]() ![]() ![]() The high beam is a bit dissapointing however, the low beam is more than enough to illuminate the road as per requirement. However, I could not find more details on the brand even on google apart from whatever is mentioned on the box. But serves it's purpose. As long as we are "focusing" (Pun Intended) on safety of our as well as others, experienting on the headlights for the cars is always a learning curve. Keep it up! |

Hello friend. I had a busy month but I'm here with the updates requested. Despite a lot of searching, I just could not find the box or pictures from when I initially installed these lights so I ended up removing the LEDs today to get some pictures! ![]() Here it is with just the dust cap removed so you can see how the bulb sits. Note how the entire assembly along with the driver unit can be easily shoved inside the housing. Nothing protruding, plenty of space in these projectors. ![]() Here is the bulb itself. Note the discolouration from the heat. They were all black when I installed it. Other than cosmetic, there doesn't seem to be any damage or adverse effects. They still work just as good as day 1. Would advise a larger dust cap if you can actually find a good quality one so they can breathe better. ![]() The driver unit along with the connection to the original holder. The little black connector you see below is where the original halogen bulb was connected. Its all plug and play. Zero alterations required. The entire thing can be shoved into the housing. ![]() Here it is with the OEM dust cap installed. Clean, OEM look and no one can tell the lights have been changed until they open the dust cap. Plenty of clearance but a larger dustcap could help with the cooling by providing more ventilation. | |

Looking at the LEDs you have posted, it does seem like you have overpaid for it unless this was bought 5 years back. Look at how thick the stems of the LED are. The thinner the stem and the closer the back to back LED chips are to each other, the better it will mimic a halogen bulb filament size and the better the output will be. If you are satisfied with the setup, it's okay. It's not worth changing until they die. | |

| Re: DIY: LED headlamps upgrade for stock halogen projectors (Hyundai i20) Hi Cresterk Would you be able to suggest a good bulb upgrade for the i20, 2023(March) sportz. I am a bit confused. On the philips website there are plenty of them listed https://www.philips.co.in/c-m-au/car...-bulbs/halogen. Thanks |

| Re: DIY: LED headlamps upgrade for stock halogen projectors (Hyundai i20) I have i20 magna 2012 model and it does not have fog light. Headlight throws is very poor as it has normal halogen reflector. Can the same bulb be fitted ? Also if any suggestion for installing fog light. |
