hey guys i need help. whats the difference between a slim ballast and a regular ballast. i am going to get 10k but i have no idea on getting the slim or regular.

bregular ballast is big n bulky and harder to hide, slim is smaller and a lot easier too hide, they do the excat samething, so just do yourself a favor and get the slim ballast. Less work to hide.. or just save up and do it right with a retrofit

Pockyy

if you must, then get the slim ballast. easier and smaller to mount to everything. i have 6K HID's with a slim and i just use double sided tape to mount it on something. lol the regular ballast is too fat to fit anywhere so just get the slim!

+1... but if you are getting a kit i highly suggest not getting 10k... If you want to do a kit get 4300-5500k. The 10k color will be purple and light output will be bad.

i had 10k before and its not that bad. i don't drive that much at night anyways. i just like it for the looks.

...agree with post that 4300k is good headlight color choice...

In my former life, was industrial color technologist, matching colors under different light sources.
"Daylight" lamps have a blue tint and are supposed to mimic the color of (indirect) light reflected from a clear (blue) sky, with no direct sunlight. These tend to have a "cold" appearance.
I didnt really study all that b4 bot my set of HIDs -- just looked at pictures in the ads. Now it makes sense.

Bot Xentec 6000k bi-xenons for hi-lo dual beam ; included was relay harness for hi-lo switching and fat ballasts.
Found the 6000k too blue for me... so researched and traded for 4300k -- like them much better. They are white and illuminate the road and white signs as white light should, not as light blue. In my town, the stock HIDs on BMWs, Infinits, Lexus, Mercedes, etc appear to be 4300k -- not blue like my orig 6000k bulbs. The 43ks are sl bluer, less yellow than stock halogens -- a good thing. These 43ks dont say, look at me look at me look at me..... yay, since dont want police to look at me. 35w are 3x brighter than halogens --wouldnt want higher wattage, defeating the lower wattage advantage -- easier on all components. One ballast was DOA -- replacement is good.
About light -- White light =all colors, all visible wavelengths. So if not white, then less light output.
And last opinion, if not white, then they are less natural, and less safe for driver and opposing traffic.
