H3C to H3 conversion

So I'm tired of paying for the expensive rare H3C bulbs for the SW20 driving/fog lights, so has anyone done the conversion to the more common and cheaper H3 globes?
I hear that its just simply running a ground/neg wire from the housing/clip to the plug and I was hoping it would be this simple on the MR2 as well. 
Thoughts?
 
Cheers
 

my auto sparkey sells them for $2 each. only ever blown one.

I've blown two, looking at HIDs for the fogs down the track as well.
I've just installed some H3 LED bulbs to try them out (they were cheap)
The light is pretty crappy, but at least the conversion has been done now.
Just ground a wire to this screw. You do need to know which of the two wires is positive though.
 

I've had good results from Phillips globes, they do seem to last well.
 
Btw for people that don't already know, sw20 driving lights as fitted to Aus del cars have a long throw narrow beam, which is why they were set to only come on with the high beam h/lights.
Unlike many Jdm cars that have fog lights with a short throw, wide beam. You can't tell the difference between the two just by looking at them in daylight. The inside reflectors are different.
Just a thought for people wondering why some fog/driving lights throw a different light.

That's quite interesting...
So the best combination for here in Australia would be the JDM fog light system (with steering) and ADM lenses. It may not be the best legally, but it would make it more useable for corners and the like.
Josh - No worries. Sounds good. The weather looks like it will be pretty miserable for a Victor run.

ADM lights would be legal if they only come on with high beam and are able to be switched off.
 
Agree, factory fogs are essentially useless, would be good rigging them up as day time running lights to make your self visible without having to pop up the lights.  But that would be illeagal, which is a shame as you could aim them correctly so as not to blind oncoming traffic and enchance your visibility.
 
Not sure it would be possible to swap the lenses (easily), it all looks glued together.

Mine have been rewired to come on with the parkers. (previous owner)
I regularly use them for this, particularly in rain, because with the LED globes in them at the moment, it really isn't putting out much light. The reason, is the reflector 'cover' distorts the light pattern of the LED...
 
The whole driving light/fog light debate is getting much harder now that daytime running lights are on the scene 'standard' in new cars. It wouldn't be hard to invert the circuit so that they come on all the time, EXCEPT with headlights. Obviously, angle and pattern would need to change though.

My experience in  Vic is that even with 20 watt globes custom fitted to the driving lights to use as daytime runners and properly wired to only come on with the ignition and off when the h/lights are on, the cops reckon they are fogs and illegal just because they are mounted in that spot.
I was pulled up and warned, absolutely no use arguing with them. You'd have to fit something ADR approved with the spec sheet in the car.
