Is this swap for cosmetic purposes? I ask this because LED bulbs are not matched for the factory lens, and thus will not project light properly. This is the case with any LED bulb for foglights/headlights etc.
To answer your question of "what you need"........LED bulbs is all you need if your goal is to swap to an LED bulb.
Yes it is for cosmetics, but, I would want the light to project properly.
So, what options do i have in order to get rid of the yellowing of the standard fog lights?
Good (and legal) fog lamps produce white or Selective Yellow light, and use tungsten-halogen bulbs. Xenon or HID bulbs are inherently unsuitable for use in fog lamps, and blue or other-colored lights are also the wrong choice.
The fog lamps' job is to show you the edges of the road, the lane markings, and the immediate foreground. When used in combination with the headlamps, good fog lamps weight the overall beam pattern towards the foreground so that even though there may be a relatively high level of upward stray light from the headlamps causing glareback from the fog or falling rain or snow, there will be more foreground light than usual without a corresponding increase in upward stray light, giving back some of the vision you lose to precipitation.
I don't necessarily agree with everything this guy says, but this is dead on, and having driven several cars with excellent fogs, I'd say the Genesis is not one of them. I don't believe any bulb will help, so if you want a cosmetic upgrade, a 5K high power LED is fine and is pretty close to the low beam HID's. They don't do much besides look pretty, but neither did the stock bulbs. I posted pics in another thread.
Sylvania Silverstar Ultra bulbs are a little whiter and brighter. Also people have installed 5000k HID ballast and bulbs.
Er, no they aren't. They are white because they have a blue filter on the bulb, and that is also the exact reason for why they are NOT brighter. These are not overwattage bulbs so the filter only cuts light output. Not only this, but the blue tinted light is also less beneficial to your eye sight than OE-equivanlent yellow bulbs.
Your fog lights should only be on in poor wear to begin with. If you have them on on clear nights you're doing nothing except hurting your night time vision despite what you think, specifically your distance vision, which is a majority of what matters.
I do not know where you buy yours at but the two sets I have put on do not have a blue coating. You can go to Sylvania's website for more inf.Er, no they aren't.
