0:01 Remove the caps from the rear
0:05 Heat the headlight to soften the sealing
0:11 We put the headlight in a carton box and heat it
0:15 1600 Watt heatgun for 16 minutes
0:23 Remove the lens clips and rubber
0:44 Seperate the lens from the housing using a flat screw driver
1:14 Remove the H7 halogen bulb cap
1:20 break off the cap channel with a plier
1:28 Place the small rubber washer over the projector shaft
1:33 Insert the Bi-xenon solenoid wires through the cap shaft and insert the projector through the fitting
1:43 Place the H7 adapter ring and secure the projector nut
1:59 Don't tighten it fully yet, you might want to do some final rotational adjustment when the headlights are mounted on the car
2:04 Mount the bulb holder
2:20 Click the shroud centric ring inside the shroud (this shroud has been modified for fitment)
2:23 Apply a few drops of glue to be sure the shroud will stay on
2:50 Remove all finger prints using a fine cloth
3:00 If you want, apply some butyl to make sure the headlight will be free of moisture
3:20 Press the lens on the housing and bake it again
3:48 Now that the sealant is soft, press the lens on the housing using pliers and secure the lens by placing the metal clips
4:17 Place the solenoid plug back on the wires
4:25 Connect the H7 high beam splitter for the solenoid to function together with the H7 halogen high beam
4:49 Drill a 20-22mm hole in the bulb cap to guide the wires through
5:16 The wires will be connected to the ballast and H7 low beam plug. Because the Audi A4 B7 has Canbus, this is the only wiring setup that can be used
5:22 Insert the bulb in the projector and secure it with the clip
5:48 Connect the 12V ballast wires correctly, red to the yellow cable (+ positive) and black to brown (- negative)
6:07 Click the cap back on, you are ready to mount the headlight to the car and enjoy a luxurious Bi-xenon projector headlight! :-)

𝗢𝘂𝗿 𝗦𝘁𝗼𝗿𝘆:
Retrofitting refers to the addition of new technology or features to older systems. These days there are a lot of people who put a simple plug & play xenon kit in their halogen headlight housing in an attempt to improve night vision and looks of their vehicle. In fact they don’t realize that their headlight beams are often worse than before. Night vision achieves relatively little improvement on night vision because of a poor beam pattern, which increases the blinding of other road users. This is because their headlight housings are designed for halogen and not xenon.
A true Bi-Xenon projector update is now possible for your car. Such an upgrade will significantly improve your light output from 700-2100 lumens to 2800 and 3500 lumens, without blinding other traffic with glare from your headlight. Upgrade your headlight OEM style!
The latest high power Led bulbs will upgrade both the exterior and interior lighting system of your car. Led lighting is becoming more and more popular in the automotive market for obvious reasons. They have longer lifetime, use less energy and improve safety with their fast response time.
Do you have any questions? Do not hesitate to contact us, we are happy to help you out!
Good luck with your retrofit!
These products are not ECE-approved and must not be used on public roads in any exterior application. Use on public roads will invalidate both the operating license and insurance coverage.

Love the heat gun box hack.

Thanks a million on this video. Great, straight to the point, and no extra bs.

[@MuhsinunChowdhury]

meow.

[@johnhere1426]

Thanks for answering me Retrofitlab So up till now i understood that the solenoid or the black and red wires are responsible for making the light switch from low to high beam mode. So it means that when I will have these lenses installed on my car's headlight I would only have to connect the solenoid to the lens in order to make it high and low beam lens

[@picollokano]

Thank you ! :) Have a wonderful day !

Hello, friend! It is normal this projector shake when the vehicle is moving even in places plans?

[@UPCarTuto]

I'm using rubbers and are properly tight, eatou xomeçando to suspect that the vibration comes from the lighthouse baffle, already took a case like this? Type it vibrates a little tried to shoot and the cell captures not.

[@UPCarTuto]

+Retrofitlab Really the problem is the lighthouse, confirmed yesterday. Thanks for attention. People here always ask where the best place to buy projectors always indicate your website.

[@R5GTT]

Amazing idea and may have to try this with my golf gti mk5 lights. Well done retrofit you sure know your stuff 👍

[@mohamadalamenhijazi4510]

U r doing a great job. It's not easy at all to be done at home.

[@TheGorgievski]

Did you fully remove the old rubber sealant before inserting the new one or you just continued putting the new one?

[@Retrofitlab]

In this case the headlight is sealed with butyl, which can be reheated and reused to seal the headlight.

[@TheGorgievski]

Well, my headlight also uses bytul rubber but I can’t find any one to buy, Can I mix the bytul with other sealants or the best thing is to remove all the bytul and use completely new sealant?

[@Retrofitlab]

@@TheGorgievski just add some headlight butyl :-) www.retrofitlab.com/en/accessories/butyl-rubber-sealant.html

Could you guys make a quick video of these installed on the car just showing the low beams then switching to high beams??. Do the projects do both low and high beam?

[@justinschanel52]

+Retrofitlab is there specific kit that we need for our audi? or are they just the mini h1 kit you guys sell and does any bezel fit around the projected?

[@devengutierrez8758]

No problem man...keep up the great work.

[@garlikas]

Don't you have to align your lights properly before asembling them completely? And if yes, how is it done?

[@Kthng]

so a normal blow drier will be enough to heat up the lights to break the seal?

[@capitalparts2905]

Why couldnt you use a H7 bulb like the original setup? Or does the B7 have H1 instead of H7 for the dipped beam?

[@ocingur]

Great job! Congratulations.

[@larrytty]

that box u made... any special consideration when u make that box?

[@larrytty]

thanks man for the reply! will take note of that:)

[@fa2919]

How do you adjust the horizontal alignment of the beam..I've been retrofitting for years but can't find another way than putting the headlight on the car and adjusting against a wall before putting lens back on..any tips?? Thanks

[@thecurlymonster]

at 3:45 what sealant/rubber did you use ?

[@Retrofitlab]

Hi .. your video is very interesting! The method you use to unstick the glass is very ingenious, congratulations! A question I wanted to ask you: where can I find only glass? Thank you, bye.

[@linusseidl9441]

Is there a solution that would be allowed in Europe (Germany to be more specific)? It looks really awesome and I would love to install it on my A4.

[@Retrofitlab]

Headlights are tested/approved as a complete part, combined with the internals (projectors). OEM/original projectors also don't have an e-mark/ ECE approval because they are simply part of the complete headlight that is approved.And making any changes to the internal parts which are not made to replace*, is not allowed (at least not in the EU). That’s why we need to mention it on the product page. So despite the light output and pattern is better than new and more safe, replacing the projector is technically not allowed. Regulations differ between countries and between vehicle types. They also change regularly. Buyer is ultimately responsible for checking and deciding if a part is legal for the intended use by the buyer. *Except for the bulbs / ballast, those parts are 'designed' to be replaceable and do have an E-mark / ECE approval.

[@stephentoye630]

Hello super job. Do you know if u can do them on an audi b8

[@MinistrantOfSound]

If I want to connect high beams only to the projector solenoid (I don't want to use standard halogen high beam bulb anymore - only bixenon) do I need to use bulb error canceller on "high beam->solenoid" wire? This concerns car with canbus.

[@MinistrantOfSound]

Thank you for answer. I want to save the bixenon look, so no halogen bulb needed for me :) Will do further research on your hid kit offer.

[@jbads1989]

What are those wires that are connected to the retrofit? What do i connect them to? I have seen any videos talking about them.

I'm trying to install an LED strip in my headlights, planning to go for the same approach but using the oven. So, what temperature do I set my oven at? And is it possible that the heat will melt some of the plastic or wires of the LED that I'm going to install..? I'm gonna go check out the specs of my LED strips tho.

[@xulunj3206]

[@Stevemc93]

Thank you!

[@4363654]

I found out that both metal washers (one and 3 toothed) both have iner tooth positioned on the wrong side. This washer should provide correct center position of the projector (same as with H7 bulb) and here this can't be done. What is then the point of providing something that is done wrong? Also on the backside of projectors there are no left/right markings. Shouldn't left headlight light 40metres while right one should light 80 metres? Also I see no point of gluing the black plastic ring to the projector since mine goes quite hard on the projector and can't be rotated, but I see problem with chrome shroud, since it can be rotated left/right a bit and durring the drive this will certanly move out of the center.

[@4363654]

I've checked my headlight and found out that small one toothed washer fits perfectly and lock up into position, so I guess something is different with your headlight here on the video or it is just the picture that does not show all the details. I also found out that only OEM projectors comes with left/right markings and that correct beam pattern is determined by the shape of solenoid acctuated iris. BTW I also tested the projector solenoid and happily foud out that central electronic unit does not report DTC when high beam connector is connected to the solenoid. I guess vire in a solenoid acts like a bulb filament and pass the check signal through. I also coded the central electronic unit so that the low beam bulbs are allways on and I raised DRLs output to 100% voltage, so flashing will work ok. I just need to test if H4 LED (mounted to the position of high beam bulb) connected to parking light connector will pass the unit detection for burned bulb. This way I'll get original look as much as possible. My only regret is that I didn't order version 6.1 insteda of classic, since as I found out it is more effective.

[@1DrunkSocialite]

isaac Hunt The projector you use doesn't really matter. You can use any type of projector for retrofitting such as MH1, FX-r, TL, D2S mini... What matters is the wire harness used. In your case you will need a wire harness with an H4 connector. I myself have a 9007 connector but using FX-r projectors.
