But can the stock fog light wiring harnest handle the higher wattage/current bulbs ?Nliiitend1 said:They have a glass lens (allowing the use of a higher wattage bulb) and a better beam pattern due to slight differences in the reflectors. They are much brighter.
Exactly. This is why you need the glass ones if you want to run a higher wattage bulb. The stock plastic ones get discolored from the heat. The added benefit of the glass ones (besides using a higher wattage bulb) is also a better beam pattern from the reflectors, which are slightly different.EuroZX3Focus said:I switched to a 50w bulb in my fogs with the stock lense, havent had a problem with it not being glass, but I would like those procarparts ones because they look so much cleaner and my stock ones are like turning yellow = (
Did you read any of the posts in this topic before you responded? The Focus's "Auxilary Lights" arent really fog light or driving lights. They're auxilary lights. They work in conjuction with your headlights to light up the road more completely and reduce dark spots in the beam pattern (mostly right in front of the car, as with foglights, though they technically are not fog lights). The glass housings of the aforementioned lights (lens and reflector) are made for a 55-watt H1 bulb. These are the lights that actually come on the European Focus. The bulb, lens and reflector are all changed with this mod, and changed for the better. No one who has done this mod has complained of WORSE lighting characteristics. Perhaps you should read the entire topic before commenting on the "efficiencies" of the mod.Geezer said:For a fog light to be functional (in fog, snow, rain etc.) you don't need or want a high wattage bulb. The idea is to cut and reduce reflection and get the light source as low to the ground as possible. A fog light beam is suppose to be broad, not go out much more than a hundred feet or so and have a sharp cutoff so no light goes upward. If you really want to light up the road in front of you, and a long way down the road you want to use driving lights. The lens and reflectors concentrate the light in medium to narrow beams of intense light. On my rally car I had three 130 watt driving lights in addition to my 55/100 watt headlights. On a clear road I could see a half mile down the road easily at speed. Throw in some dust and they became almost useless! Too much reflection! Putting higher wattage bulbs in the focus stock fog lights will only result in uncontrolled glare since the lens and reflector were designed for low wattage applications. The bulb, lense and reflector are designed to work as one element. Screwing with any one of them will result in a less efficent system.
