Default Just a thought, HID thread

So I've been thinking about something, If I would install an hid kit on my 02 wrx and made a light shield on the low beam to block light to form a cutoff while using a 9006 bulb (since it will fit perfect. Take out the turn signal bulb and splice the wires into the parking lamp bulb so its still running on the 168 bulb. Then modify the connection for the turn signal housing to fit say an h1 or h7 bulb in there.

This way, low beam stays on all the time even when high beams are on, turn signal bulbs are moved over slightly to where parking lights are and the high beams will only turn on when highs are selected. something like this would not be an issue, I would just have to run the wires off the high beam relay switch in parallel so lows stay on when you switch them to high.

The only issue is making or getting that metal piece to make a cutoff and putting it in the housing, along with modifying the housing. I'm not too worried about hot spots on something like this.


I'll pry this later with an hid kit of my buddies so see if I can even make a metal piece as a sheild for it.



Does anyone think this would be a plausible yet cheap alternative to blinding people or an expensive retrofit kit?

basically make a light shield around the top of the 9006 bulb in place of the lo/hi 9007 bulb for a low beam (putting the shield there to create a cutoff like on projector HID's, put a high beam bulb up where the turn signal bulb is, and move the turn signal to the parking light bulbs. Then wire in the low and high beams so when high beams are on both low and high beams are on, not just high beams like stock.



This way one can have both low beams and high beam hid or just low beam hid with halogen highs, and have lows with a cutoff so as not to blind oncoming drivers.



Basically a sub $100 setup to make HID's more oncoming traffic friendly.

Yeaaaa, I'm pretty sure that's not how hids work.

If you put a shield on it, it won't do anything because the reflectors will still throw out crappy light. The only way around this is to do a retrofit.

what!?

Are you kidding me?
There are oem manufacturers that do put a shield around the top of hid bulbs to make them either not hot spot of have a better cutoff.


Also, if setup properly they have decent cutoff without any shield.
My buddies 96 civic for instance has a very pronounced cutoff in stock housings and has only two very minor hotspots. It can be done fairly well without a projector.

I'll be testing this idea today with an hid kit my buddy has and a little bit of trial and error.


Seems to me that the turn signal location is an H series bulb housing, so no modifying the turn signal housing!


EDIT!
Seems like I was wrong, the turn signal housing is more like a 9005 housing. and it looks like with very little trimming of a 9005 bulb it will fit in the turn signal housing, to work as the hi beam

If you want a good cutoff: The only way to do this would be to take the reflector housing from an HID car and transplant that into your housing. The time it took you to do that, you could have done a projector retrofit and get better better output than any OEM reflector hid setup.
What you're doing is work for no gain. Will you get less hotspots? Maybe I doubt it though. Will you get a better cutoff? I seriously doubt that.


I've seen plenty of Civics with HIDS and NONE of them have good cutoff. They all blind oncoming traffic. It may seem like, "oh wow, I can seen a pronounced line" But there's ****loads of scattered light above the cutoff.

But hey, you can try it out. It's your car, your time.

Hey i did this exact thing except i didnt do the cut off shield i just lowered the light really low but i had the same thing here are a few pics. Just so you all know i went to G37 Projectors.

Everything off


Everything on

By the way all of these have HID's in them

But the only problem is the high beams in the turn signals dont have much use they give you a very insignificant amount of light straight ahead but say if you needed to spot a ninja hiding in a tree then your good to go with these bad boys.

Killer,
It sounds like a great idea. Don't let NASIOC get you down. It seems like the past few years, you need pictures for these people to understand. Keep posting your results.

Spanky,
How well did the brights work using the turn signal reflectors?

They dont really work too well i mean you can notice when they turn on and everything but its not that much of a difference it still will give a small amount more of light and also it will let other motorists see that you do infact have brights.

So say your on a hilly mountain and you are going down the hill and have a steep up hill infront of you then these things are awesome you can see alot up that hill instead of waiting for you to start climbing.

I'm interested in how the shield throws HID light. I don't think modifying the bulb will help with the blinding because it will be how the reflectors project the light that controls the beam pattern and not the actual bulb itself.

The reason its blinding to have HIDs in halogen housings is because the way the reflector housing is positioned reflects extremely bright even if your main beams are lowered down like spanky said.

So... for example, even if your beams aren't directly pointed in somebody's eyes, if they use their own energy to look directly at/into the housing's reflection itself although they're outside of the main beam pattern, it is still very BRIGHT just because the HID optics are being reflected off the whole inner housing and not controlled through a true projector.

That said, I have HIDs in my 05 halogen reflector housings and have them aimed so its not terrible to oncoming traffic and haven't been flashed once since readjusting the beam so really anything is possible. Like litebrite says don't let nasioc get you down, to each his own, but just remember if it doesn't work out you'll be pissing off all the oncomers! I'm very interested in seeing what a shield could possibly accomplish in reflector housings. Hope my info helps and sorry for the rant... subscribed.

Well I have great news so far. I personally used my own hid kit I forgot I had laying around, its a 6k kit so it's slightly blue... but anyways. I'll take some pics of my ghetto ass shields tomorrow, made the first model out of tin... which I may stay with as it seems to hold up very well. The tin is cut so it projects a U over the top of the bulb so as not to reflect into the upper reflectors which the stock high beams use to reflect more light into the road.


So far it looks like a very good beam pattern... there is a very slight but still noticable amount of light that goes passed the cutoff but it is not blinding to oncoming motorists, just enough to illuminate signs. So... so far so good. One Problem I am having though is that just off to the center of the car in front of the bulbs toward the outside it is slightly dim. but I think I can combat this by bending the tin slightly up.

The car has a very pronounced cutoff when put up to a wall and driving on the interstate which is great. They are slightly brighter and bluer than stock-like silverstars, but like I said, not blinding to oncomers. Also there are NO HOT SPOTS!





SpankySuby, I was curious how did you wire the high beams into the turn signal space? and what kind of bulb are you using? I was planning on modifying a 9005 bulb to fit but if you used something different I'd love to hear it, because it seams that unlike your setup mine would help greatly with high beams up there since there is such a good cutoff. The turn signals I'm not so worried about... I can just solder the stock ones over to that so... meh.





I'm so pumped that this works this well! I'll be back in a min with a pic of it at night.




---EDIT!---
Well I messed with the driver side shield a bit and its slightly better than before but now its projecting light outward more... I'll have to mess with it a bit more tommorow when I go to my parents house. I'll have pics uploaded in 10 mins or so. you can see in the pics that the light is not evenly distributed currently, but then again the shields very close to what I want as of right now... they are still a work in progress but they seem to work well so far. The driver side was working perfectly earlier, cutout and everything... but had a big hotspot right about the cutout, yet no other light up there... I found that extremely peculiar, so I tried to bend it around a bit to get the light a bit better, but I bent it a bit too much and now its not throwing the light in an even pattern on the driver side, pass side is almost perfect though, just needs to be evened out around the edges so its not such a straight beam of light.


Pic showing light distribution, notice how the driver side is way off and scattered? Where the pass side is more even?

Pic from the side showing the horrible non existant close to the car light spread of the driver side and fairly decent pass side.

Picture showing clusterf*ck of fogs and HID's






As I have said already, this is a work in progress and will probably not be completely finished for a couple weeks, planning on making another model of shields to fix any issues with this shields and make them better looking and more permanent... mostly making it a much more pronounced cutoff so one wouldn't have to make their lights point downward. Eventually I may be open to modding others lights for a shield if I can get these working to a level where that have a pronounced cutoff and will not have hotspots. I may also work on a buddies 04 05 wrx's headlights with this idea if all goes well, so I can put it to use on either model year.

I don't understand what is going on in this thread. What is this "shield" you are creating? Just adding some kind if shield to a halogen reflector is not going to recreate the output of an HID projector. You would need to actually retrofit HID projectors into the headlights to achieve this effect. Your pics are useless too. All I see is really bad lighting pointed straight down onto the road, which is very dangerous. You will need to take some pictures of your "cutoff" up against a flat wall to show your results. I give you credit for trying something different, but this seems a little too far fetched to go anywhere.

Have you seen a D2R bulb? Its the stock bulb for a USDM STi HID. The bulb has a shield to prevent light output in certain directions from the bulb. It is basically a piece of metal wrapped around the bulb.

edit: Why does everyone need to see a wall shot? Last I checked, one typically drives on flat surfaces avoiding objects perpendicular to the ground. Not flaming the previous poster as I see this question alot and find it odd.

I just wired the high beam power into them and then ground to battery ground and then used the parking light with a relay to power the normal headlight (just for saftey) and wired the turn signal to the parking light all of the bulbs i used were out of a nissan, the highs were a 350 Z then the fogs were out of a m45 and the headlight out of a altima

A "wall shot" speaks a thousand words about a headlight setup. It immediately shows if one's headlights are aimed properly, and also gives a good idea of how much glare the lights are giving off. Not showing a wall shot in a thread like this, where the OP is specifically trying to affect the CUTOFF of his headlights, just doesn't make sense.

This picture was taken after I messed with the driver side... thus why it's so ****ed up in that picture... tonight I'll be in a garage where I'll be able to aim them and mess with the shield some more and get them how I really want them.

I live in an apt complex so I didn't have a wall for reference and there are really no good places to do such a thing around here... I'm going up to my parents house tonight to see if I can create a good cutoff with this idea.


Also, just wondering, what did you mean that pointing them more towards the road is dangerous? Do you not want to light up where you are going or what?

The trolls are coming out. It's just a matter of time until this will be fit for OT. Hopefully we can get some good information before that happens though.

You do realize that headlights are supposed to light up the road "ahead" of your car, not directly "in front" of your car. By illuminating too much of the road directly in front of your car, this makes it harder for your eyes to focus down the road where your vision needs to be. That is why your idea seems very unsafe.
