Yellow headlights?

[deepsleep]

So I remember reading a while back that yellow light gives better contrast. One of my headlights just went out and I figured I would just replace both. I read about the 35 buck wire harness to use more watts so that sounds good. I'm constantly getting blinded by idiot civic or pickup trucks with illegally bright lights that arnt properly adjusted.

So if yellow are the best, you guys know any good yellow ones?

I dont know about the yellows but the silverstar ultra brights are kinda nice, I eventually want to go to true HID not that blue tinted ricer shit that blinds you.

I think I'll try the cheapos and do the relay thing for a little more wattage.

nathan that was a cool find , especially since i have BLUE 10,000 kelvin h.i.d's in my 87 , deepsleep i had silverstar ultras before the h.i.d's they do help and its alot better with the harness upgrade too

Where do you buy yellow sealed-beam lamps in this country? Is it even allowed in most states?

Selective yellow is the magic word. No blue in the spectrum. Blue light is quite probably the worst possible thing you could have in the headlights, other than maybe violet. The human eye can't really deal with blue light very effectively, which is why it blinds so badly. Aircraft and seagoing boats have red instrument illumination just because it doesn't screw with your night vision. I wish lighting standards were better enforced. It gets really old being blinded by some fugly blue light that glares so bad I'm driving blind for several seconds at a time.

I think legally you have to have white light, though interpretations of "white" are pretty broad. We've all seen lights ranging from pale yellow to green, blue, pink, or purple. Not sure where you'd get legitimate selective yellow lighting in a format our cars take, unless maybe someone makes a SY bulb in an H4 format, and you could convert over to H4 lenses with the yellow bulbs. I suspect you may get some noise about it from the local police though. SY light is pretty blatantly not white.

Anyway, getting outside of that, a good quality halogen bulb and a relay kit will do wonders. I still have old headlights in my car, and the relay kit made a big improvement. Voltmeter told me nearly 3 volts improvement at the lights, and I could easily see the difference in light output.

Isn't that the truth. I didn't bother with the voltmeter, but it was like a night and day difference when I jury-rigged a relay on the station wagon's headlights. Going from that to driving the Vic with mostly stock wiring was like driving in the dark. Finally getting the lights pointing in the right direction sure has helped, though.

I replaced both headlights, what a difference! I guess the power starts to go away as they get older too. Is doing the relay thing easy? How should I measure and adjust the angle of the lights?

Relay thing is a sinch: Relay Thing

The filaments in halogen headlights cook off tungsten over time and deposit it inside the bulb. If you've ever owned a halogen lamp with the tubular bulb in your house and replaced the bulb, you'll probably have noticed they're silver looking inside. Thats not because it burned out, its the filament cooking and depositing on the cooler glass. Headlights do the same thing for the same reason. That layer of tungsten inside the glass is why they get dim.

relays are fairly easy, and a worthwhile upgrade. Related, it will also keep your headlight switch from melting again. I noticed you posted pics of yours elsewhere.

x1 it really helps out as well plus you won't strain the wiring as well too
