Changing headlights to dual bulbs (96 brighton)

[MPtyza]

Just wanted to know how exactly to go about doing this. Ive got a project I'm working on, and I'd like to use a seperate bulb for my low and high beams. Like on the stock headlight socket, which wires are which? And is there a way to have both bulbs on at the same time for the high beams, after I convert to a dual bulb system? I've searched for information on this and came up with nothing.

first you'll need something to put them in, such as the morette style lamps (with different optics for high and low beams)

As far as which wire is which, just use a multi-meter, and see. Not too hard.

For having both on at the same time, wire in a diode between the high beam wire and low beam wire. That way, when the high beams come on, so do the lows, but when the lows are on, the highs aren't. You'll probably want to upgrade the wiring when you do this, as the high beam wire wont be able to carry the current of both bulbs. To do this, you'll probably also want a relay...

So it'll be relay, triggered by stock high beam wire, with 14guage wire going from the battery, to the high beam lights, and a diode between the high beam wire and the low beam wire.

I do have a housing in the works. As for the wiring side, I would have no idea how to wire a diode in like that. I will definately be upgrading the wiring, no doubt about that. So how exactly would I wire this all together with the relay and everything? I was going to just keep it the way it is with one filament (or bulb when I convert) on at a time, but after thinking about it for a while, I'd like to have both on as highs.

Thanks for the help

Do you know how to wire a relay? That skill will be cruicial. Here's a diagram:

The thing about this is that you could just use the stock wiring, so long as your only running one set of lights. When you start running both of them, the stock wiring will fry. What you need to do is to set up a system of 2 relays, one for the high beams, one for the low beams.

Now, if your going by the above diagram, where the switch is is where your stock wiring would connect to either relay.

Do you know what a Diode is? I assume not. A Diode allows electricity to flow only one way, like a one way valve. You want to place one of these "valves" between the 2 stock wires going to the relays, so that when the High beams come on, the diode allows both relays to trigger the lights, but when the low beams are on, the diode stops the flow, and allows only the low beams to turn on.

Hope that's simple enough? If not, you might want to read up on here about relays and diodes and wiring: http://www.bcae1.com/ (diodes are section 33 on the right side, relays are 36)
