projectors....

[loud92CB7]

i got a question... i see alot of people takin the whole projector and cuttin up the headlamp to get the projector to fit... why all the cutting?

i ran across some projectors in a headlamp behind a dealership in the junk pile. tore apart the headlamp and got the projectors out... one was a h7 bulb and the other was a h1 bulb. well i really dont want anything to do with an h series bulb... im sticking with the 9006 and 9005 bulbs. so i continued to take apart the the projector the cut off shield and what not and use the lense... now this fits in the housing of a cb just fine for now. im just in the starts of my own retro fit



i already have in mind of how to adjust and makings of a shroud. but what im askin is why in the hell would u cut up a housing just to place a whole flipping projector when what everyone really wants in the the damn lense... right? i know the whole output and glare thing im just askin why all the cutting

[alkoholikwun]

my guess would be because it would sit real flush with the backend of the housing.

It's not just the lens that people want. Projectors and their lenses are like your eyes and a pair of prescription glasses...Everyone has a different prescription...Same with projectors...Different projectors, different lenses, different focal points & distances, different sharpness, etc. etc...Without the right specs, the lights will not project properly, and your output will be nothing compared to the real deal.

To do a proper retrofit you'd actually NEED the whole projector assembly...It's not just the lens that people want...If they only want the lenses, then they should just go with those rice projector headlights floating around Ebay...With your setup right now, the output probably will end up like the crappy Ebay projectors, if not worse...And about the cut-off shields, you'd need those as well.

Having said that, just keep doing what you're doing if that's what you want..I could be wrong, maybe the results will be even better than the other retrofits. But to answer your question, the reason why people cut their headlamps open is so they can fit the whole projector assembly into them properly. By assembly I mean reflector bowl, lens, and everything else in between. Hope that helps, and good luck with your project!

very well put ronald. what he said is all true.

i wouldnt do it that way if it was me because the 9006 and 9005 are meant to be bounced around alot then out the housing onto the road. where as the d2s bulbs that most projectors use are focused inside the reflector bowl for great output.

you also have ot understand that beautiful cutoff line will not be present since your not using the cutoff shield that comes with the housings and reflectors bowl.

to me your light output will not be as good as you think because its like your taking a light bulbs and placing a piece of scratched glass in front of it that is basically what your doing

I hate to tell you that you are wasting your time and what you are doing is wrong.
Like the other member said you need the whole projector, not only the lens.
The chrome inside the bowl of the projector bounces/reflects the light into the lens which magnifies the light and with the help of the metal shield in between the projector directs light into the ground/road.

To make it even worse the projector you have is a Valeo H7 high beam, not low beam, meaning that you can not even use the whole projector in your low beam because will send a very narrow beam and higher.

In order to properly fit projectors into most headlights you need to cut part of the rear of headlight.

The way you are doing it very little light will get to the lens and this little light will not go to the ground and most likely will block light and cause glare.

You should the right thing and retrofit xenon projectors in your headlights to get 3 times the light output, wider, brighter and with light cutoff.

You can try to see how is the light output now against a white wall at 25 feet to see how will look compared to the stock headlight before you keep wasting your time and effort.

first off part of your statements are shit. this is my project not your so dont tell me sumthing is wrong! u dont have parts sittin in front of u so u have no clue what i have.

well i actually havent decided on the cutoff shield... to use what came with or to make or grab sum others. and from what i can see bulbs are bulbs im not talkin the filament im talking the sizes and model (h1 h7 h4 9005 9006) they all mount the same from what i have seen.

ronald thanx for your input i actually like ur explanation and examples. you may be receiving some PMs in the future related to this.

so technically u dont need the whole projector u need the lense and the cutshield correct? the housing that holds the cut off and lense can easily be remade to fit into the cb's housing in my opinion??? being all thats left behind the cutoff is a reflective housing?(in my case)

[slick]

yes theoretically you dont need the whole projector. just the lens (which you have) the cutoff shield and something for the light to bounce off of. now if you could focus the light beam into the lens you would be ok. maybe try to make like a shroud to encase the light to only reflect into the lens that would help you out.

[loud92CB7]

im thinking i need to have a budlight tonight and make use of the empty can

[slick]

sounds like you got a good plan

[acc0rd_adicti0n]

i wanna go dumpster diving too

Almost, you also need proper spacing between the source of the light, the cut off shield, and the lens.

Focal properties of the lens dictate that spacing between the source of the light and the lens need to be just right for the sharpest reproduction of the cut off. If the spacing in the projector is not replicable in the stock housing, you could techincally use basic ray tracing to figure out how to reshape the focal radius your lens.

That's not gonna be easy for the average tuner, so either use the stock specs for the projector or play around with it. Without that spacing, the cutoff will be fuzzy at best.

gotcha thats an answer i was wanting to hear that i was worried about i got my screws and nuts tonight now all i have to do is play with the cutoff shield

You asked questions and advise and I gave it to you; you do not need to be rude.

I have been playing with hid stuff for many years, did retros in all my cars and had and have most of the projectors, ballasts and bulbs that exists, just to name a few: LS430, TL, S2000, TSX, etc...

Once again you are wasting your time and you will be lucky to get some light out of that lens going to the road and if you add the shield and put a shroud around lens holder/opening to direct light to the lens the light output from that shield is super narrow and will throw light higher and in the middle will be even higher which will cause glare to oncoming drivers. I had like 10 pairs of those Valeo H7 high beam halogen projectors and I know what I am talking about; too bad you do not appreciate a good advise.

Can't wait for the results, post pics as soon as you finish and good luck, you will need it.

Probably was better to laugh at your project, left you waste your time and let you learn from your mistakes and save my advise to somebody that appreciates a little.

[loud92CB7]

My bad I'm sorry I was a bit rude. I getba little pissed when I'm told I'm doin wrong on my own retro fit. Now with that done u said u have done retros before if so got pics? Maybe that could help inspire some ideas.

If u know so much about the projectors then u would have notice I took them apart. There isn't a cutoff right now that's sumthing I'm gonna fab up or take off another assimbly. These projectors are both out of one housing so one was a low and one was a high beam. Now the glass for both is the same it's the cutoff and bulbs that were different and that's what I'm wanting to change.

Now can sumone explain or prove what is so good about an h4 bulb? Just so I can fully understand

[accordztech]

here is my retro

if ur going to change the lens, you may have to play around with lens spacing to obtain the best focus. honestly you got it open, put at least some e46's in there, or go bad ass with tsx.

i run fx35, but now i run them at 55 watts d2s. not much in color, but the light is very bright.

h4 bulb is a high and low beam. thats the only thing great about it.
