    right basically.
    after testing my headlights out I've encountered a problem.

    as I predicted the main beam replacement is much brighter than the dipped beam, but the beam is focused onto one spot.

    any idea how I can scatter this so I get a wider beam?

    cheers
    I'll get some pics tomorrow

    glue a cone in the bulb.. over the top but in free space.. will reflect all the beam to the rear reflector of the light... that or just stick a tiny disk of mirror or black tape on the front of the lense..

    ahhh...i've jsut done a few tests with a house light bulb, and the lens from the headlights....and it appears the further back the bulb is....the smaller the circular beam is....so bring it closer to the lens?

    just do what minor says..... thats the correct way looool

    you dont lose light intensity lol

    come'on you never seen bulbs with caps in the end??

    the way your describing is how torchs work, which is gona be a lot of fucking about to get the correct beam of light

    i don't understand minors way... :emb:

    how can you glue a cone in free space? ....over the bulb....without enclosing the area? :wtf:

    by using a cone...
    have you really not seen bulbs with caps? go have a look at any new car they have them

    it blocks direct light, so the mirror pushes ALL the light at the same intensity out, creating a better scatter

    it happens with these type of lights

    whys the main stronger anyway? they not the same lights? look the same

    can dip the bulb into somthing like solder (altho there are bulbs that have cover capsa on them, not too hot wiht bulb technologey tbh) the new vw's actually have vw in the cap... WAY trick

    but ye, 2 bits of metal.. or swap out for capped bulb's

    you find me a picture of this cone setup please?

    1 minute....i'll take a picture of the lights so you can see how they differ.

    here...
    basically if you look the bulb for the main beam is seated much further into the headlight...so i had to extend the other dipped beam piece that i cut off a spare set of lights i had to make it fit.
    but now, the beams gone funny.....

    so where exactly am i going to glue the cone?
    to the inside of the lens? :wtf:

    ok so you want both lights on at the same time in the dipped position?

    :rofl: ahh i must be talking like a right dodo.

    i'll try explain as clear and crisp as possible.

    my main beam is focusing too much onto one spot.
    even though it has the cap on the bulb....
    i just wanted to know if there was a way i could make the beam wider so it's not onto one spot.

    rite ok one last question, hav u got a pic of the lights before you modded em?

    cos if youve moved the lense on the right light forward then your gona need to move bulb aswell

    go get a torch and wind it forward and backwards, every mm makes a difference as you will notice. Apply EXACTLY the same physics to what youve done, its hard to explain what you need to do when i havent touch them lights but physics NEVER change

    the bulbs fine :cool:
    ahhh...maybe i'll just go with the torch theory :rofl:
    only need to drop it a little close to the lens and it should be ok.
    i'll get it done tomorrow and let you know how i get on.
    but if you have any better ideas let me know please :D

    ohh btw minor....what you mean by putting a mirror disk or black tape on the lens....hows that going to make it wider?....it'll just cut a bit of the light out won't it?

    yes mate.....the picture above...the one without the cover on...thats how the lights are standard....just the reflective backing ;)

    thats the whole reason i've done this mod....so i can have it look as if i have two dipped beams...as it looks much better.....BUT the main reason being, with the cover over this bulb also it will protect the bulb from rain as i no longer have a lens on it do i as i cut it to form the new shape of the lights

    so basically before...there was no lens....nothing to direct the beam except the reflective backing...so now that i've put this lens on it's buggered up the beam....and now it shines to a point......but with the tests i carried out with the lens and a bulb....it appears if i move the bulb close to the lens it should make the beam wider....so it should work...i'll try it tomorrow :nerd:

    thanks for the help

    this is another thing you need to understand, the bulb creates light only (simple ino lol). the headlight itself creates the beam, just cos you block out the top of the bulb it still pushes all/more light out the side.

    soooo much easier to explain with diagrams etc. but im sure you'll understand, you got this far so u ent a donut.

    i knoww that yar....thats easy.....i meant if you put something onto the lens....not the bulb.....
    because if you cover a piece of the lens surely it's just restricting how much light it will let out...rather than changing the shape the beam ...other than cutting a part of it off.

    ahhh right ok well FULL beam as you no it is full light hence the BIG mirror, the dipped has a lense to direct light down not just out and forward. the full beam is a simpler technology than the dipped beam....

    basically look at both lenses and see the difference, cant really see how your gona sort it tbh cos ur using the same lenses :confused:

    but seems the torch theory and lenses are your best bet to test and adapt, personally can see it being alot bit of fucking about.....

    why not just convert so both are dipped beams? full beam is shit on my ped, prefer dipped..... would look better having both lights on at the same time and would probably be easier

    i've got no choice i have to sort it :rofl:
    i can't convert both to dipped beams, that's even more hassle than this!
    i'd have to cut out the rest of the dipped beam part off another set of lights and mould it into place on this light which will take ageees.
    than i'd have to rewire it all so they come on at the same time.
    and my dipped beams are crap :rofl: ....unless....i took the plate out...see how the beam goes then....it may be ok...and then convert the other one....
    either way...its a hell of a lot of work
    i think i'll just get these lights as much sorted as i can....and if all goes bad....i've always got spare standard lights.
