Hey yallz. I wanna wire my bimmer lights so that both the inner and outer lights act as both low beams and high beams.
For example: when I turn on the headlights to low beam, both the inner light and the outer light are on low beam. when i turn the headlights to high beam, both of the lights are on high beams.

Do I just attach both of the high and low beam wires to each of the lights just like they are on the original stock headlights or what can I do to achieve this lighting arrangement?

 

If I remember correctly the bulbs are different wattages so on low, the high beam would not be at 100%, if you just juncion the wire together. I think the best way would be to hook up two relays which would run directly from the battery (fused of course) and when on low, the first relay would kick on the brights, then when on high, the second relay would kick on the low beams. I do know that you don't simply want to junction the two hot wires together, no, no, no. I would think though, that doing this would defeat the purpose of having to even put on your bright lights. The only real thing that would happen since both lights will be on all the time, would be when put on bright, your driving lights (if you have them) will go off. Though, you could just run a low amp fuse so that the light being run off either of the relays would burn only at like 50% or so But, if I remember correctly, it is illegal to drive all the time with your brights on, you may get in trouble. Be careful!

 

i wired the inside light as my low beams and adjusted the beam down a lil it looked good but i did get a ticket for haveing my high beams on and it wasnt my high beams that were on.... the cop told me that the inside light were lit and those r supposed to be for hig beams

 

Ok.... so the 9005 and the 9006 bulbs are unlike the 9004 bulbs and cannot act as both high beams and low beams like the stock?

Are there any bulb sizes that are similar to the 9004 bulbs(ie. to make the light both high and low beam without additional relays) but are small enough to fit into the bimmer lights?

 

you cant just toss two 9004 bulbs in each of the BMW buckets? wouldnt that solve the problem? or couldnt you get some other dual filiment bulb?

 

If you notice, the socket sizes are different for the BMW bulbs, one is smaller than the other. Just the same, the bulb for the oem Nissan light is different also, just the same, it is disigned for a different KIND of socket as well. The BMW sockets twist in (which I like) instead of like the Nissan which has a cap which screws in and secures the bulb. Maybe the relay is your best bet, but I'm sure someone knows more about wiring than I do!

 

9005 and 9006 are single filament. 9004 are dual filament. 9004 compromise the beam pattern of the low beam to fit in a dual filment light. hence a separate high and low beam shines better and have better beam pattern.
u can't switch the bulb types. that will defeat the purpose of having a separate high and low beam.

to properly wire the lights in you need to split the ground wire. there's two positive wires and one negative on the 9004 socket. split the ground to high beam and low beam..wire the low beam hot wire to the outter lights and wire the high beam wire to the inner light. if u want to run all 4 at the same time then just run w/ highbeam all the time which is very annoying to other driver, other drivers will flash you, give u unfrendly gestures, cut u off, yell at u..etc etc..basically don't do it. the lights were not designed to run that way 24/7. you should've researched the lights before you got into this project.

 

So you're saying you want BOTH bulbs running all the time?

as dan said, you don't want to do that.. in fact, it's illegal. you can/will get a ticket for shining your high beams within 500feet of oncoming traffic.

the only thing I recommend doing is hooking a relay to your high beams that will shine both the high and low when you have the highs on...
when you have the low beams on, only the lows shine.
that will give you the best visibility, and still be completely legal.

As it is now, the low-beam light will turn off when you flip to high beams... basically all you're doing is making it so that the lows are always on.

 

Ok.. My original plan was to replace the 9006 bulbs with 9005 bulbs(4 9005 bulbs) which are the lower wattage bulbs I think. Then I planned to only hook up the low beam wires to each of the lights so everything would only be a low beam light. I could care less whether this is legal or not because cops are stupid anyways and pull you over for the stupidest reasons and they don't think. Anyways, the only reason I want high beams is so that I could flash my friends if I ever needed to send them a message to pull over.

 

IMO, that's about the dumbest thing I've ever heard. just leave them alone instead of increasing your chances in getting pulled over. give them a reason and they'll do it. They're not stupid, just doing their jobs.
If you want to signal your friends to pull over, you don't need brights.. buy yourself a damn cell phone and call them. everyone has one nowadays anyway.

 

i agree. you beat me to it matt.

 

hahah Matt, i was trying to post last night but the database crashed -=P. Yea dude, Butnik, you shouldn't be messin with the cops dude

 

Well, I already have a cell. Flashing is just a whole lot quiker than the phone.. that's all. And cops are indeed stupid. They're not just doing their job... otherwise ... practically every single person on the road would have been pulled over. Cops choose who they want to pull over, not because they have a sense of duty. Of course, this is a generality.... there are some good cops that make reasonable decisions. However, in my experience, cops have been useless. They're there when you don't want them to be there and they're not there when you really need help. Oh.. and here in sf, they tend to abuse their powers as well. Many times, I've seen cops turn on their lights to speed and run red lights in order to grab a bite at the local donut shop. Maybe where you guys live, the cops are better. Until I see a change, my attitude towards cops remains the same.

 

Oh and before I forget, thanks for the suggestions Chris Greg.
