Do we have any V40/S40 owners who replaced their factory bulbs with aftermarkets? If so, which ones did you replace and what brand did you use?

hi!<P>are you talking about the H7 headlight bulbs? if so, Daniel Stern and some others have offered a more high-efficiency H7 bulb that draws the same power, but allegedly sheds more lumens,... i haven't tried them yet myself, but find the idea interesting; just not to the tune of over $20-something/ea until i know more about them.<P><BR>cheers!<BR>e<BR><P>

One of the sad things about the aftermarket parts market is that nobody actually tests their claims, and headlights are a particularly bad area. <P>There are many aftermarket bulbs which claim improved performance, but actually DECREASE amount of available light. Not all bulbs are the same, there are some that are better than others, but seldom it will justify the cost. Stock headlights, on the other hand, must meet certain standards with that particular car.<P>One thing I think is particularly funny is the way that kids nowadays lower their cars and install all the aftermarket lights. But you usually have MUCH better light performance simply by just getting a headlight alignment after you change the geometry.

I agree with u joeflies that there are bulbs out there that just simply, are just for show and they luminate the road worse then what you started with in stock. The reason why I brought up this question, and it does not relate only to the headlight H7 bulb is that I was thinking of changing the stock ones. I'm just trying to figure if there is a remote possibility of getting true Xenon for the S40. If not, I guess a set of PIAA's would be the next best thing although they cost around $100 a set.<P>Ray<BR>

(however studies are showing that the human eye is better at picking up detail from light that is more yellow in spectrum than blue, casting doubt on whether the HID lamps are really more effective. the initial impression is that bluer light is brighter, and that the HIDs are putting out "more light" leading one to believe that there may actually be more light available, when this simply isn't true.)<P>lastly, i'd have to agree with you that many vehicles would benefit from a headlight alignment after suspension modifications. in fact, some EU countries actually require headlight aiming adjusters to compensate for variances as slight as passengers and load.<P><BR>cheers!<BR>e<BR><P>

They emmit a light that is as white as daytime light. From certain angles you may think they are bluish but that is because of the angle. You are seeing one of the colors of the white light which is blue! From certain other angles you may see yellow or even pink!<P>Yannis<BR><P>

("Now how much would you pay?") <IMG SRC="http://www.swedespeed.com/ubb/wink.gif"><P>until they can get an evenly colored beam across the entire dispersion area, they've still got a way to go. for now, they're certainly not something i'm going to be willing to pay extra for, and would happily prefer a good quality Quartz-Halogen! <IMG SRC="http://www.swedespeed.com/ubb/smile.gif"><P><BR>cheers!<BR>e<BR><P>
