Default Convert fog to driving lights?

I have my fog light assemblies apart and it looks like I could easliy remove the little hood that shields the lamp and creates the sharp cut off. With that removed and a 100w H3 in there - is there any reason I wouldn't have a nice set of driving lights?

I never drive in fog and use the fog/Daytime running lights as my only illuminatoin around the city, day and night.

Thougths?

If you are not changing the reflector or the lens the light will still be cast in the pattern of a foglight, except the center will be brighter because you've removed the shield. They'll be real annoying to oncoming drivers.

what about a euro light like the one inside the turn signal on the euro 944 bumpers?

IIRC, the driving lights aren't specialized for LHD/RHD, only the headlights. I think the driving lights have a flat cutoff.
A friend of mine has an 83 euro spec, I'll check his lights =)
I'm about 75% sure that the driving lights mount in the same fashion that the fog lights do. However the fog lights have slanted lenses, the driving lights have flat ones, I think....

I have 100w H4s in the turbo fog lights and they are good for just after dusk and maybe some city driving at night, but they don't have a good enough pattern for regular night driving... even with the higher wattage bulbs.

Modifying the lamps by removing the shield would change their pattern, making them blinding to oncoming drivers.

Fog lights are short range, wide pattern lights, with the shield inside the lamp to give that "flat top" pattern....which is designed to keep light from reflecting back into the drivers vision. They are not designed to have the range of headlights, therefore are designed to compliment them, not replace them, regardless of the wattage of the bulbs.

Removing the shield inside the lamp, AND changing the lens design would turn them into driving lights. I believe these lamps are Bosch, and as such, replacement lenses should be available.

Driving lights are almost the opposite - narrow pattern, long range "flood lights", designed for distance illumination.

With all lights, (other than HID) the larger the lamp, the more light and better pattern.

I came across a site where they make Turbo look alike bumpers. And mentioned that customers reduce the cost of making their cars look like turbos by using a set of Chevy silverado head lamps. they may work, this way you could keep fog and add a driving light.

Are you talking about something like these? The euro fog/driving combo lights? The PO of my old car removed the popups and installed these as a replacement. While I have no clue how I passed PA inspection, they did work very well for all purposes except back road driving at night. Here they lacked a little, but they were still almost as bright, if not as bright, as the headlights on my '99 Altima. However, I do prefer better lighting on a car that is as fast as these cars are. Oh yes, the other problem was that people told me when I would pull up behind them at night, they could not even tell I was there! The lights were too low to be seen if I was sitting behind someone at a traffic light. Thank goodness no one ever backed up when I was behind them!

Good luck finding the lenses and casings for Euro NA driving lights. (to be read: give up now, or close your bank account)

Those lights would be ok for city driving, I would NOT want to drive on a dark highway in your car.
The issue is light QUANTITY and ILLUMINATION DISTANCE, not lamp brightness.
And your comment about over-driving your lights is a very important consideration.

There is no doubt that I agree with you completely. This is why on my new 951 the popups remain, and I still may add the euro driving/fog combos. I think the best upgrade is an IceShark kit, but I have yet to have the money around to buy one.

I've seen a 951 with these installed. It looks kinda crappy, because the silverado lights needed to be angled in, relating to the 951 bumper, in order for the beam to go straight. The fit also wasn't just right, it basically looked like someone stuck the wrong light in there.........

badass, from what i have seen, it will cost you as much to buy the euro lenses as to buy the Iceshark kit. I have the fog/driving combo as well as H4 headlamps and the light still ain't great, at least on low beam, the high beams light up the countryside though.
