Just one last little post regarding color and light too (for those folks who can't seem to let go of the idea that "blue" is better): Ever wonder why shooters glasses are amber? (And not blue)?

... Selective-yellow light can improve a driver's ability to see in fog or rain or snow, but not because it 'penetrates fog better' or 'reflects less off droplets' as is commonly thought. That effect is known as Rayleigh Scattering, and is why the sky appears blue. However, it occurs only when the droplet size is equal or smaller than the wavelength of the light, which is certainly not the case with ordinary fog, rain or snow. Roadway Fog droplets are several orders of magnitude larger than visible light wavelengths—no Rayleigh Scattering.
So, why do yellow fog lamps work better? It's because of the way the human eye interacts with different colors of light. Blue and violet are very difficult for the human optical system to process correctly. They are the shortest visible wavelengths and tend to focus in front of our eyes' retinae, rather than upon it. To demonstrate this to yourself, find a dark blue store front sign or something else that's a dark, pure blue against a dark background in the absence of white light. From any appreciable distance, it's almost impossible for your eyes to see the blue lighted object as a sharply defined form...the edges blur significantly.) Blue also is a very difficult color of light to look at if it is at all intense...it stimulates the reaction we call "glare". So, culling the blue out of the spectrum lightens the optical workload and reduces glare. For more in-depth discussion of the matter, see Bullough & Rea's excellent study on the topic.
Note that I said "start" and not "just". There is literally hundreds of thousands of threads (316,757 as of this posting) packed with tonnes of information! Search through there any questions you might have and post questions that may not have been answered. That site is the closest thing you'll have to a class (that is free).
Also, to avoid being ostracised by people who hate answering questions that have been answered hundreds of times, !!PLEASE!! take advantage of the search button!! You might try terms as simple as "wiring" or "f150".
Ok, I'm done, time for lunch. On a side note, I have learned 90% of what I know over there. They cannot know everything over there, though they try. Don't get put down by the mountain of information, just take one step at a time and, before you know it, you'll be [insert step type] down the other side.
I am not sure if you can help but I have a 93 F150 and would like MUCH brighter lights, what should I go with, I also would like them to have a blue tint if I can..
yes sir. true HIDs. I have 5000k and theyre a pure white. 4300-6000k is the band where the most usable light is. 8000k is bright but has a lot of blue and the higher you go it turns to blue to purple and at like 30,000k its bright but mostly haze and only for show. and in some states its illegal to have anything over 12,000.
if your just wanting the bluish look go with 6000k if you dont mind driving with a headache and eye's that you feel like tearing out with really not more light output. if you want useable light that you can drive all night with and have impressive white light output go for 4300K. if you hve a 93 you probably have the frosted headlamps which HID's suck in, you'll blind other driver's and it wont throw much more light output down the road, your best bet woud but a set of aftermarket driving lamps and put those on your bumper, if you just want the bluish look buy halogen blue tinted bulbs. they say 30% brighter but it's actually 30% dimmer, it looks brighter because the wave length of blue light scatters much more then white, amber and red. also dont run the high wattage (100watt) halogen bulbs without going through a relay first, you will fry your harness.
^get HIDs if you really want bright. I pulled one of my HIDs out and just one headlight is way brighter than my friends 2 halogens on brights when mine is on its lows. yes its that bright.
