    Anyway ................... You can see how shallow these units are. And don't forget, you can also move them forward as well. The other thing you'll notice is, the bulb holders point downward and don't actually stick-out like the OEM ones. This also gives you a little more space >>

    Yeah, thanks mate, that last one and a few from a previous post were uploaded directly from my computer, like an attachment, it seems to be the only way I can upload images. I remember having a photo album a while back, but it's not there anymore!? That's why all my other photos from previous posts are missing.

    Thanks Active8, I do have the 'Advanced Editor' selected with full WYSIWYG.

    As I've spent an awful lot of time in the workshop these past few weeks, I just wanted to upload a project update to show where we're at with the project. Doing it this way will be an absolute ball ache, but if that's the only way, so be it! Maybe I should ask Dan to look into it?

    Ideal... Just the info I was waiting to hear.
    So, are the classic range lights brighter that the standard headlights?

    Yes mate, even the 'Classic' range are far brighter than the T4's standard setup. The 'Performance' range are bright still
    But it's not all about how bright a light source is, it's more to do with where the beam is directed and how far down the road you can project the beam. What you really want is to see the road ahead, and not light-up the entire country side!

    Personally I think the old T4 OEM oblong headlights are a thing of the past, you just don't see car headlights with the reflectors etched into the glass anymore. You just can't beat a good projector type headlight unit for low beams. Firstly, the 'cut-off' point is so distinctive and so well pronounced that visibility can never be matched when compared to the OEM headlights. Adjusted correctly your low beam should look like this. These are the Hella 'Classic' range >>

    And now the Hella 'Classic' range high beams - Straight away you can see where the beam of light is concentrated, right in the middle and further up. And much brighter >>

    Those tests were carried out without an upgraded wiring loom as I hadn't designed it yet, so the results can be even better than those in the pictures. The other thing to consider is, when you adjust your headlight units, particularly on the OEM setup where you have the H4 dual filament bulbs, you can't raise your high beam to see further down the road as this would also raise your low beams, and you will only blind oncoming traffic. With a quad headlight system you are free to adjust your headlight units independently, low beams as per legal requirements and your high beams slightly up in order to see more of the road ahead. Add to that, on a decent quad headlight system all four units can be ON at the same time when in high beam!

    Hi guys,


    Yeah, I know, I'm still at it! getting rather close now though.

    I had to redesign my headlight covers ( the transparent ones ) witch meant I had to remake the resin tooling plugs, and by simply by adding a 'swag-line' has made a missive improvement. I'm still testing PETG and getting rather good results, the clarity I'm getting is not bad, and the overall structure is quite strong as well surprisingly. As I'm testing with 2mm PETG. Next up will be the 3mm Polycarbonate. For the time being though, 2mm PETG is fine to get me to the next stage.


    Not exactly clear as in like glass, but getting there, also you'll notice that there's absolutely no distortion >>

    And a close-up of the 'swag-line', the strength that step down adds is quite surprising, and it adds a bit of 'form' to what was quite a boring shape on my previous headlight cover prototype >>

    You'll also notice in the pic that I'm still getting a little bit of 'webbing' on the vacuum formed part. I probably heated the plastic sheet a little too much on that occasion, and the tooling plug' shape doesn't help too much either, having near vertical sides on a tooling plug is never a good idea when thermoforming plastics ...................... but that can't be help, as that's the shape I need.

    Right now I'm fine tuning stuff, making all the individual parts to fit precisely together, is almost as hard as actually making the parts themselves!

    Cheers for the update Turk. I like the design with the Frosties image - It'd be pretty cool driving up the M1 at night with other motorists thinking they're being chased by a pair of Tony the Tigers.! They're Lllllllllate ..... I mean Grrrrrreat!

    Keep us posted - "hats-off award" to you for the dedication.

    Some very cool pics there chap.

    I know it would be a ball ache but is it possible to polish the clear plastic back to a good shine?
    Just thinking that the webbing could be sanded/cut down and polished up, if it is going to be an issue long term?

    Headlight covers all marked-up ready for the next stage >>

    As there's another part to go inside the assembly for the clear cover version ( in front of the headlight mounting bracket ), I need a bit more space inside the assembly. One of the issues making these parts 'universal'! All this faffing about will pay off in the end though I think. So, after measuring everything again, I re-measured everything again! ( as you do ) and came to the conclusion that 4mm has to come off the bottom of the headlight mounting brackets. That should make the brackets sit a tad further in leaving me a little more room behind the covers >>

    The next stage will be quite interesting, I can't wait for it actually, I've been 'collecting' various round containers for the past few months, supermarket shelves are a great resource for this, all sorts of different packaging! I do get stared at though ................. not the done thing measuring containers with callipers in a supermarket!

    But if I get caught and somebody asks what I'm doing, I've got my line ready .................... Just making sure it'll fit in my cupboard!

    Hi Jim, and thanks mate.


    I'm working on the eradicating the webbing all together mate, a malformed part isn't a good part in my book. As extruded plastic sheets are 'Hygroscopic', basically they are prone to absorbing moisture from the atmosphere, which causes the plastic sheet to bubble when heated. Millions of tiny microscopic bubbles in clear plastics even though not noticeable with the naked eye, dulls the clarity of the plastic.

    Simple solution ................. buy new stock! But this is purely the testing stage, so I'm using up old stock.
