are these high/low? and how long is the life span?

Yes, Hi and Low Beam. Unfortunately, I don't know how long they last as not long after replacing the bulbs I sold the car. They were much brighter than the Sylvania bulbs in the car, though.

They are high/low. No idea how long the lifespan is. I haven't had them very long.

I've had mine since April 2011. One low beam went out just today September, 2014.

They work the same as OEM with high and low. The lifespan will be less than the OEM bulbs and I have found that they are no better than the OEM's that they replaced but were a lot more money. In my opinion, they were a waste of money for my truck.

not sure. i kept them for a few months before use and they still worked fine. it seems to me that they should last for a pretty long time

They should be perfectly fine for a very long time. Ive the intact strips running on a 11-14.3 volt system and they work just fine in that range. Ive only had issues with one strip because of a crack in the rubber shell letting water into it

YOU CAN THEORETICALLY leave them on 24/7 for ten years and they will not only last but never downgrade...I could go into scientific data about it but it'd better if you go online and read because it is a very long date article...u have some very very very ofl old on my refugium that's been on all day everyday and they are as bright as the day I built then....

Ive used them 6 plus times and they still have lots of "life" left in them. As long as you dont loose the top they will last a long time.

I haven't had them installed long enough to comment on life span. My after-market daytime running lights utilize the high beam filament so it's on all the time, no premature failures yet. I do use the high beams as much as possible at night but with traffic everywhere they don't get many hours in a month on high. My Ultras have lasted for 60K and I have both of them in the zXe box as spares. High/Low? Yes, 60 watts high, 55 watts low.

Celeste, I currently own 6 of them and they are close to being 6 years old. However, I really don't anticipate they will last forever, I have read several reviews of units lasting as long as 15 years. If mine give out today, it's a cheap investment, and they work...

Candidly, I don't know. Some folks have had them last a long time; other folks have had them die within a few months. I think it is obvious that the quality control and or the quality of parts used is questionable. I have had several months of an awful picture, and the first episode of an awful picture happened when it was about 2 years old. The bad picture lasted 2-3 months.

Depends on how you [ab]use them. If you often run them all the way down, and/or run them down only 1 or 2% and back up to 100%, they may last less than a year (or only take half a charge after a while). If you seldom run them below 30%, and don't recharge until they're 90% or less, they may last 5 years or more.

HI, i am not sure how long they would last, but i had them installed for about a year now and no problems at all.

Not sure, but I have kept them up to 3 years in the original packaging and they have worked fine.

I've only had mine for about 2 months, so I can't speak for how long they last. Fortunately, no issues thus far with them.

They are good for a couple of years according to the package. I've had them on the shelf for a year without issues. Brian

Yes high & low.Very good to me as far as life span. My other truck unfortunately was totaled (dent in the door). & I bought a newer '97 Toyota Tacoma 5-spd. These easily transferred over to my Tacoma. I have been using them on it for about 3months now? They were on my other truck for about a year. Work great. They are definitely some of the whitest I have ever seen.

I bought a pair of these in late September. After about 150 miles of running something within them has given way and makes a noticeable rattling on the control (right ear) side.. They still work though, but just bear in mind that they are a consumable that will not last for years on end. Given that they are rechargeable, I figured I'd get about 18-24 solid months out of them, but sadly that may not be the case. I'll use them till they fail or if the rattling becomes overly obnoxious. I've used them in warm temps, freezing temps, light rain and snow and they work just fine. They aren't water/weatherproof, but given the physical breakdown I'll have no qualms against using them out in the elements. I bought a pair of these in late September.

Yes, they have about 6 months of life. To help you remember when you have to change the filter, the faucet comes with a small battery and has a light indicator in the base.

Yes, they are ageless!! For a small object they present efficiency, compactness and reliability!!
