Wanted to see what some of you thought...I know either can be dim at times depending on what it is.

I have sealed beams on my old Nissan pickup, and composites on my Corolla. The Corolla's headlights are much brighter, especially on high beam. I wish we would go back to sealed beams, however. The composites are hard to aim, and seldom are aimed. They are often too bright for oncoming traffic, and are way more expensive than they're worth. Sealed beams are inexpensive, do an adequate job, are easily changed and aimed.

I love my clear-lens composite headlights. My only complaint is that the plastic hazes over from UV exposure so replacement is almost inevitable.

i like composites because they tend to look cool

thats all, really. the car i have now is my first with composites. they do glow brighter then any sealed beams i've ever driven, but its nothing to write home about unless comparing them to my old volvo sealed beams. i drive that car at night now and can't believe how i ever got by with them. i can't see crap

i want to get me some of those blue bulb things when i get replacements, 'tho. the xenons or w/e they are called

Replacement bulbs for modern headlights are highly variable. If you buy the cheapest bulbs you can find at a discount store, they are not nearly as bright as a more expensive name brand.

Many auto parts suppliers such as AutoZone carry a composite headlight restoration kit which is like a polish. It'll make them look like new again. I've used it on some that were actually yellowed and it made them look just like new.

Those blue or rainbow bulbs aren't any brighter...that's all just for looks. That's just a coating on the halogen bulb. I actually think they are not as bright as the standard halogen.

Xenon headlamps are a completely different thing and are VERY expensive. You're vehicle has to come factory equipped with all the special wiring and such for xenon (or you buy an expensive conversion kit). They draw a lot more power, get hotter, and they don't turn on immediately (with a tiny delay like with a ballast for a fluorescent bulb)

Those must be those GD purple/blue headlights found on European cars and Cadillacs. Those d*** things nearly blind you if you don't look away!!

Well, xenons are a very pure white light that might look a bit purple at an angle, but yes, they are BLINDINGLY bright to oncoming traffic.

Xenon conversion kits have actually plummeted in price, with (great quality, hard to believe, I know) Chinese made systems readily available online. It's advisable to avoid installing them in cars without automatic headlight leveling though, as you'll easily blind whoever comes towards you, especially if you don't have projection headlights.

It's also worth mentioning that not all "bright" halogen light bulbs are merely coated for looks. The bulbs from high quality manufacturers like Phillips and Osram are filled with Xenon gas, which allows for higher intensity burn, without significantly higher temperatures. They're generally also coated with a mild blue tone because the whiter light more accurately emulate daylight, which is better for the eyes as well as giving you more visibility. Though they're not revolutionary, I've owned several different types, and they do provide noticeably better light, both in color temperature as well as intensity, the downside is that they burn out much faster and cost about twice of a standard bulb.

You're not supposed to look directly at them anyway, bud.
