Hey guys,
i have been using some 6000K Euro Dezigns xenon headlights and I love the nice white/blue colour, but they are @!#$ty for driving at night time...does anyone know how to improve this or know of any bulbs that are good for night driving as well?
Gary
this is probably irrevalant, but i used to use Sylvania SilverStar's in my snowmobile and couldn't complain..i could see about 100 yards up the trail...give them a shot..their about 18 bucks a pop..
I've always heard that the more blue tint it has, the harder it is to drive at night. I think the same goes with the higher the K, less light is on the road but I don't know for sure. I have Eurolite Super Plasma. They look better than stock but still keep a lot of white light on the road.

True the higher the K the less light it puts out.

I used to have 9000K Blue Xenon's in my LeSabre, and the view was just terrible. They were such a great blue, but you couldn't see distance with them at all basically, so I put back on my stock lights, lol
Silver Stars, not blue at all but can see everything on the road.
silver stars are my choice, I have been having more trouble seeing at night in the last couple of years when i got the new cavi I couldn't see for $#it. i got the silver stars about a month after I got the car. I will not go back, an definite improvement over stock. was that a good enough testimonial? lol
The "K" is the color temp, not how bright the light is. heres more than you ever wanted to know. its not too long though.
Color Temperature
Correlated Color Temperature (CCT)
Kelvin
(Term of photometry)
Color temperature is a simplified way to characterize the spectral properties of a light source. While in reality the color of light is determined by how much each point on the spectral curve contributes to its output, the result can still be summarized on a linear scale.
This value is useful eg. for determining the correct film in photography depending on the lighting (resp. for determining the white balance in digital photography), and for specifying the right light source types in architectural lighting design. Note, however, that light sources of the same color (metamers) can vary widely in the quality of light emitted. One may have a continuous spectrum, while the other just emits light in a few narrow bands of the spectrum. A useful way to determine the quality of a light source is its color rendering index.
Low color temperature implies warmer (more yellow/red) light while high color temperature implies a colder (more blue) light. Daylight has a rather low color temperature near dawn, and a higher one during the day. Therefore it can be useful to install an electrical lighting system that can supply cooler light to supplement daylight when needed, and fill in with warmer light at night. This also correlates with human feelings towards the warm colors of light coming from candles or an open fireplace at night.
Standard unit for color temperature is Kelvin (K).
(The kelvin unit is the basis of all temperature measurement, starting with 0 K (= -273.16° C) at the absolute zero temperature. The "size" of one kelvin is the same as that of one degree Celsius, and is defined as the fraction 1/273.16 of the thermodynamic temperature of the triple point of water, which positions 0° Celsius at 273.16 K.)
Technically, color temperature refers to the temperature to which one would have to heat a theoretical "black body" source to produce light of the same visual color.
Some typical color temperatures are:
1500 K Candlelight
2680 K 40 W incandescent lamp
3000 K 200 W incandescent lamp
3200 K Sunrise/sunset
3400 K Tungsten lamp
3400 K 1 hour from dusk/dawn
5000-4500 K Xenon lamp/light arc
5500 K Sunny daylight around noon
5500-5600 K Electronic photo flash
6500-7500 K Overcast sky
9000-12000 K Blue sky
now the guy at the counter can't lie to you about the "brightness" or "color" of the bulbs your buying. 55w bulb is a 55w bulb, the color of the light will tell you haw well you can see at night, more is not always better.
ok, well , the silver stars sound great...next question...where is the cheapest place to buy them? I am in Canada so i'll have to have them shipped here...

If I understand correctly, a light should have three things
Blue tinge
-blue is the longest wavelength and thus travels farther
Lower temperature
-less dissipated heat = more energy left for light energy
Higher wattage
-brighter
No?

less temp, less energy being used less light output

dude no u wont, im from winterpeg and they sell them everywhere here. canadian tire or parts source are ur best bets.. but dont expect to pay no 18 bucks a pop like someone said they're around 24.99 for one. or u could try to silverstar ultras which are sold in pairs and they sell for about 54.99 parts source had em on 15% off but i dunno if they still are or not.. i have both the low and highs and am very happy, had em on my old cavy too 100% better then stock.
