Depo V1 Headlight Bi-Xenon Mod - UPDATED Page 1

Post by TobyE82 » Sun Nov 08, 2015 8:20 pm

Hi All,

A lot of you may have read through this post when I did it first time round, however as I revised them, I will revise this thread accordingly.

I have recently completed my second version of bi-xenons retrofitted into a set of my Depo V1 headlights. The light output was far too poor and virtually non existent in the rain in standard Depo's, so this will improve your visibility no end.

Before and after.

Image

Back to the beginning. LED's in Depo V1's. Not the best.

Image

Image

First off, I bought a set of projectors from The Retro Fit Lab in the Netherlands. They are the H1 2.5" Projectors and also an H7 - H1 solenoid wiring harness so that full beam works the shutter.

Image

I also had to make a new bracket / adapter plate for the projectors to be fitted into the original mounting holes of the headlights. I found this to be the most tricky part of the whole mod, but mostly everyone should be able to undertake this.

I bought some small bolts from B&Q to mount the plate to the projector then used the original bolts to mount that back to the headlight.

Image

I started making a template bracket out of card so that I could adjust it to fit and change any errors I came by. This proved to be quite tricky as its not see through to which I had a bright idea to use an old milk bottle as its translucent, its much easier to see where the bolts need to be. one cut out and holes drilled through, I mocked it all up to see how they looked. After I was happy with how they sat and make sure they sit level. This will be how they sit when all fitted back on the car so this is quite important to get right! I cut out the final plate out of 3mm Perspex or Acrylic - which ever you prefer to call it. They can be bought pretty cheap on ebay. I went for clear as it would be easier to see through and work with, even though its hidden out of site it does really matter. (if you were a little more handy, you could make them out of steel or aluminium or similar, but I don't have those resources, but my way seems to work just fine!

Image

Image

Once this is all done, its just a matter of bolting the projector back into place and plugging in all the necessary bits and pieces, including the harness that I bought with the projectors. There doesn't seem to be any other place that sells them apart from Retrofitlab but making one isn't too tricky.

However...

I went a step further and split the headlights so that I could change the angel eyes. I thought the led bulbs which I switched out for the standard yellow bulbs looked crap in daylight. Not too bad at night, but still, you could see the 4 bulbs per ring and cheap was screaming out at me.

Image

After splitting the lights which I placed in the oven at 120'c for around 7 minutes. (I do not take any responsibility for this if you copy this! You are not baking a cake, you are softening the sealant so it becomes soft and easier to split the lights)!!!

Image

Angel eyes out, rings out, all bulbs out, as many of the wires out as you can just so you have a blank canvas to work with. I bought some COB LED rings from ebay. They are very bright. I was worried they wouldn't be very bright but i couldn't be more wrong. All my phone photos honestly in the dark just look like the headlights are on! haha. The inner ring is a 95mm ring which I found from China. The larger outer ring is 100mm and fits very snug, but does fit around the edge of the projector shroud. You will need to sand the end of the shroud very slightly so the ring sits back enough for the ring cover so slip over the top of. I sprayed the outer shroud black so that it matches with the OEM units and left the inner one chrome. Again, to match with the OEM look.

Image

Image


The rings are made with a gel coated top which is yellow. They still light up white, but the yellow is very visible. With a bit of playing around, I found out that if you spray a thin layer of white or primer spray paint on them, so it is consistent the still shine through very bright. This eliminates the yellow for when they are off and keeps everything looking as neat as possible.

You can see through the lens cover a yellow tinge.

Image

Sprayed primer

Image

Still bright

Image

I have had some questions about what I did with my inner lens. First time around I covered it with a translucent plastic cover to give it that adaptive xenon look, however, my version looked a little tacky to me, so I changed it.

Image

I updated it so that if you use another projector shroud, if you cut it down enough, it can sit on top of the halogen full beam edge. In this I fitted a glass lens from the old projectors out of the Depo's. It needs holding in place, so I hot glued it into place. Once set, that shroud can be suck into place. I used some resin glue for this as it's clear and not so thick/messy. Probably a lot stronger as well as it really smelt. Haha. Also, just to mention... I used some smoke black tint film to stick on the back of the glass so it matches the outer lens. You also cannot see through it vey clearly so nothing is given away when you look in.

Image

Image

Image

Image

Image

With that all set in place, I soldered the angel eye wires together so they light up together, and snipped the old plug off the old angel eye wiring harness, soldered the rings to that, so it was just a matter of plugging them in. All bulbs put back in, I went to test them in the car. All worked as they should! I also noticed that you can test them with a 9v square battery. That provides enough power to light them up well.

With the inner lens in place, it has a flat back so reduced the depth of where the bulb can go. A standard H7 halogen bulb is too long by about 8mm. I searched for the smallest H7 bulbs that I could find and came across these. I didn't care if they didn't project light as I needed them to 'fill a gap' and also so you can flash people when your lights are off as I haven't figured out a way of tricking the xenons into flashing when they are off. Turns out they are plenty bright enough to look at, they just don't project it, which is fine.

Image

Image

Image

Image

For a cheapo H7 LED, I fitted a canbus load resistor so I wouldn't have any errors and all would work correctly. I also did the same for the angel eyes, although I don't know if this one was necessary as I didn't try without.

If all is good and everything works, which it did for me, I married the lens back up to the body and back in the oven for the same time. I bought some butyl on a roll. If you want, even though I don't think you have to, although I wanted to be extra sure they were sealed. Apply this around the edge of the light but stretch it as you put it in so its about 3mm thick. You only need a little to add in otherwise too much and it won't seal together properly.

Image

Image

You can see the spring preloaded shutter for the full beam solenoid - and the cut off.

Image

4300k HID's because - Factory spec of course. (You will also need to change from H7 bulbs to H1's).

Beam cut off...

Image

Image

Image

This is just rings believe it or not

Image

Image

Image

Image

And that concludes my write up. I can confirm everything works as it should, with no errors, flickering or issues. I had a little condensation on the first day of use which I drove 130 miles in the cold and heavy rain. Once they settled and had been in for a few days or so, they no longer mist up whatever weather. (Touch wood).

I have started offering my services for anyone who would like a set or their Depo's converting. Price will vary on what you want doing, but get in touch.

Cheers,

Toby

Good work Toby, I'd seriously suggest you offer these services to make something like this Toby and atleast 10 people on here would snap these up, myself included.

Maybe even we provide all materials and you add your costs on top?

Where do you live Toby?

That would be a good plan actually! Although probably still quite pricey to buy! May have to adjust the plug pins too! Yeah, see how you get on!

I would say it costs around £120 ish to do. I had to buy a couple of tools and bits and pieces though, so a little more for me.

It depends how handy you are really and if you have patience or not! Aha

I honestly wouldn't mind doing it if people wanted it doing. I'd obviously have to charge a cost for doing it. I'm not sure how much places charge for retro fitting? Plus I guess it would depend on if you want the rings doing and gutting them really.

But if people do want this doing, obviously it works and I can do it if wanted.

I'm based in Exeter in Devon. Probably out of the way of most of you I suspect? Haa

Strangely enough, it's all cleared up. I even washed it yesterday and pressure washed around the lights and still nothing. Like I've said before though, they will be coming out again and I will be resealing them properly as a precaution!

Look great and look really OEM from the photos.

I think the only thing I would have done differently is changed the frosted inner cover for just the fish eye style that the OEM xenons have.

They almost look brighter than OEM as well!

Thanks for the positive feedback!

Basically took the plans from my head. I plan on improving the inner lens. It's good from a distance, but close up it looks a bit cheap. So a 'new' lens cover will be mocked up and replaced.

Really happy with the light output and Ring brightness though!!

Hi Toby mite sound a daft Qs but did remove all wiring before u put them in the oven. And another the temp does it have to be different for fan ovens as they get hotter with the fan blowing mate. Gona give this mod a go. were they easy enuf to line up. ( I no would still require setting up from mot centre ) I'm just in about the projector inside the headlight as once it's back in the car wouldn't be easy to adjust. I've been looking at mini h1 projectors on eBay not sure how good they are but look very similar to the ones you have in your setup.

Hello mate.

I removed all the ones I could. However, the ones connecting to the back of the plug on the internal of the headlight - leave them. They are heat glued in anyway.
I put them in at about 100'c for a few minutes and that's a fan oven as well. Just be careful like I was and you'll be fine.
I found it helpful that under the lights is a flat base. Use that to keep the light level then just align the projector and make sure that's sitting level. If you drill the holes in the adapter plate a little larger, there's more room to adjust.
I think it depends on the quality of the shield and the shutter/cut off. When I compared that to the depo projector, it's a big difference in the step of the cut off.
I know there are cheaper options out there, but I didn't want to scrimp on them as I was worried they'd be just as terrible as the Depo's.
