What color are the headlights on your ride /o/?
>>13843351
They're white halogens
Like every normal persons car
>>13843351
Stock H4 bulbs/white halogen, because I'm not a faggot.
5000k is best Kelvin
>>13843351
car is from the 1960s
so I have around 3000 kelvin
>>13843351
Stock Xenons like a none poorfag. So in the 4300-5000K range
>on your ride
This always make me cringe
>>13843386
Tell people you're going for a classic GT car look anon.

I shouldn't have kek'd but I did.
>>13843351
4500k or get off the road.
sorry i got old and can't handle the glare.
4000k I suppose, if halogen counts
8k hid with 15watt fogs that I leave on always
>>13843357
You know, most cars outside the shit-tier econo-box category come with Xenon lights. And luxury cars are starting to come with LED lights.
3000k because it is the best.
>>13844114
Halogens are still popular because they allow for single source operation that HID lamps do not.

BMW is stepping it up to FUCKING LASERS. As if HIDs, LEDs, and other high color temp lights don't burn my eyes badly enough already. This shit pisses me off.
>>13845214
Color temperatures isn't intensity and they wouldn't bother you if people could be assed to properly aim them.
Since we're talking about headlights, I just moved up North to Canada. First time driving in snow, what's the best thing to do to improve visibility without being a dick to oncoming cars.
>>13845223
This, mostly. But fucking blue lights are annoying to me.

>>13845206
.... and?
>>13845214
The new laser-headlight technology looks amazing... hoping I'll get a chance to try it out in the future
>>13845241
Get good bulbs like Philips Xtreme Vision 100s or Osram Nightbreakers and make sure your luminaires are in good condition.
>>13845223
Color temperature is a simplification of the actual emission spectrum of the light source. Halogen and incandescent bulbs have smooth, broad emission spectra. HIDs and LEDs have peaky, discontinuous spectra. For equal intensity there are less different frequencies of light. The human eye can perceive the most contrast in the green range of the spectrum. High color temperature means less green and red, more blue. high color temp lights are closer to that of the sun, so looking at such lights makes your eyes adjust closer to sunlight conditions whereas lower temperature bulbs help you retain your night vision. When dipshits drive past me with their high color temp high beams on, I'm literally blind for a second or two after they pass as my eyes readjust to the darkness.
>>13845269
Thank you, I'll look into that.
>>13843351
4300K No hihger
>>13845241
Low-beam; set your lights up properly, polish your headlight-glass, get some good bulbs (Philips Xtremevision 100/130's or the Osram Nightbreakers)
High-beams; basically the same deal, but you could also consider adding extra headlights to the car that activates together with your original high-beams
Note about the Philips; I've heard that the 100's are better than the 130's. I haven't had a chance to test them both out, but I am very happy with my 130, with my high-beams having become noticeably more powerful and longer reaching
Are your reflectors in good shape?
>>13845214
protip: "laser" head lights ARE LED (LED lasre genius) where a UV emitting LED later is beamed into a plastic block of phosphor which emits the visible light. It's a component system LED. (And the idea is about a decade old)

You don't really want to be using high beams during snowfall, anyway.

>>13845301
I just realised that I must've used 70% resizing instead of 30% for that one... will be corrected
>>13845296
>>13845305
Depends on how heavy the snowfall is I guess. I've never had the need to turn mine off, just lowered my speed slightly
>>13845319
If it's light snowfall, sure, but medium to heavy snowfall will preset many reflective particles that will blind you.
>>13845291
Thank you! Did a quick Google search and I'm finding a lot of 100 > 130, I'm also looking into the Night Breakers but it doesn't look like it's available here. Don't wanna order online because I need it immediately.
>>13845324
Tightly-grouped long-range beam that sits quite low means that on my car the snow that is high enough for me to "see" isn't really illuminated
>>13845325
Are you in the US? If you are, you're going to have to order online, anyway. Parts store are full of Sylvania garbage. Get whichever is cheaper.
>>13845344
I'm actually in Canada, not sure if that's better or worse.
>>13845353
I'm not sure what is available there. If you can get Xtreme Visions in the store, go for it.
>>13845368
Well fuck me, local Canadian Tire is full of Sylvania shit like the other guy said.

>>13845296
Indeed. And both systems suffer the same problem: you can't completely absorb and fluoresce all of the monochromatic light coming from the source, and it bleeds into the light exiting the bulb. In fact it makes up a large proportion of the total amount of light the bumb emits. This is very very blue light (~450 nm), which is only picked up by one (blue cones) of the four (blue green red cones and colorless rods) receptors in you eyes. white phosphor LEDs have a huge gap where broad spectrum lights peak out, around 500nm (green), which is the wavelength of light your eyes are MOST SENSITIVE to.
>>13845429
![human_cone_action_spectra[1].gif](https://i.imgur.com/uAuO6s3.gif "human_cone_action_spectra[1].gif")
this is the absorption spectrum for the receptors in your eyes.
note the low sensitivity in the blue region and the high overlap in the same region as the halogen / incandescent bulb emits in >>13845445
There is a reason why when europe banned incandescent bulbs there were provisions made for certain uses, like theaters. Broad spectrum light sources emulate the properties (not necessarily the color temperature) or the sun; there are more "colors" emitted, you can see more, and they just look better than semiconductor and fluorescent-based sources.
>>13843363
I disagree 0 kelvin is 0k

Sylvania halogens ftw
>>13843351
>tfw HiD blue
>muh rice
Had 3200? Led`s for exactly three days before returning them. Overpriced pieces of s***. The color wasn't so bad but the beam pattern was very blocky could see four distinct right spots when shined on my garage doors. Some of them were higher than where my high beams shine. Replaced with PIAA 5000
>>13846188
cool. how many lumens you pushing? seems like 10k +
I assume that's an led light bar not hids or something mounted on your roof
>>13846334
The round ones are doing the most work, and they're only doing 1400 lumen each. The bar is pointed at the ground and is doing less than 18000 lumen.
I put yellow headlights. Looks and works good.
>>13846188
>>13846418
Do you turn your lights off if there is incoming traffic?
>>13847634
Nope. Too much work. Fuck them, I need to see.
>>13847634
Yes, it's required by law.
Do yellow fog lights penetrate the fog better than white ones or do they just reflect less glare off the fog?
>>13848853
Does Australia have no legislation on lighting?
>>13849031
'White' and selective yellow lighting has been shown to perform pretty much the same.

Won't be a trouble - brakes are good, bearings are good, recently done a proper alignment, shocks and springs are strong, no leaks on the engine or exhaust, tires are good, lights and bulbs are all fine. Also the garage I use don't say anything on my extra headlights
The only thing I got a minus for in 2014 was a small crack in the glass on my left headlight (replaced it the day after, had a spare one laying around) and the front wheelbearings needed to be tightened a bit, which took me twenty minutes and they didn't even bother checking it when I returned

Jesus, try finding the lens profile for your camera so you can remove those appalling chromatic aberrations.
>>13843351
OEM, although I briefly had 12000K bulbs, but they exploded literally half an hour after I installed them

>>13843624
You do a lot of night rally?
One of thesse days when I quit being lazy, and quit adding things to my backlog of projects, I'm going to throw together some LED arrays and mount them on my bike. I want to see what color profiles actually provide the best visibility at a certain power output.
I think green as a tertiary light source to my OEM headlights would provide better visibility than any cool temp HIDs.
The human eye is more receptive to some wavelengths than others, and some wavelengths disperse in the atmosphere faster than others.
>>13851058
Please do not do this shit.
>>13851119
Give me one real reason why I shouldn't.
I've got plenty of forest roads in the middle of nowhere to ride around on, and I'm not replacing my headlamps.
>>13851138
>Give me one real reason why I shouldn't.
You aren't an engineer and humans can't assess how well they see.
>>13851150
>You aren't an engineer
Thats a really hilarious assumption. Especially since you think putting an array of LEDs together is difficult.
>and humans can't assess how well they see.
The most retarded statement ever made by anyone ever.
A standard test is to affix a light to set point and illuminate an object at a known distance, then take a picture with a camera using consistent manual exposure. This gives you a repeatable baseline to compare against. I'd do it indoors, but I don't have a stretch long enough to illuminate with a full scale accessory lamp.
>>13851177
>Thats a really hilarious assumption. Especially since you think putting an array of LEDs together is difficult.
The hilarious assumption here is that you think the difficulty is in putting the garbage together.
>The most retarded statement ever made by anyone ever.
Better tell that to the lighting companies that spend millions on photometry equipment.
>A standard test is to affix a light to set point and illuminate an object at a known distance, then take a picture with a camera using consistent manual exposure.

Hilarious.
Guess you got it all figured out. Enjoy creating completely useless lighting equipment that endangers you and others.
>>13851190
I never said I was going to use it around other traffic, and I never said I was going to be replacing my stock lights. I explicitly said I'd be adding a tertiary light. No matter what wavelength the light source is, adding more light will not decrease my visibility. There is no inherent danger in any of this.
Dismissing a basic visibility test, which is a industry standard, only shows that you're immaturely shitposting. You don't have any basis for your arguments, you're blindly making assumptions without having any background relevant to this. I do.
And again, if you think putting an array of LEDs together is hard then there are no words. You're just an idiot.
>telling an electrical engineer that he isn't an engineer
>>13851219
electrical engineering isn't real engineering
any real engineer knows this
>>13851226
All electrical engineers know that "real" engineers couldn't tell if something needed to be wired in parallel or series if their lives depended on it. God forbid you filter anything for EMI and put a fuse on it.
purple lights best lights
