OSRAM64150SV2-HCB Silverstar 2.0 H1 Halogen Headlamp Bulb, 12V, Duo Box

Let me start off by saying that having used them on our last two cars, I'm a huge fan of the Osram Night Breaker Plus 64150NBP H1 12V 55W Twin Pack of Headlight Bulbs - they really do make the standard OEM bulbs look like candles, without blinding oncoming traffic.I recently took ownership of a new car and was once again amazed at how dim the OEM headlights are!With winter well on it's way, I logged onto Amazon to order a replacement set of the usual NightBreaker Plus bulbs. While I was looking for the correct model (H1), I stumbled across these NightBreaker Unlimited bulbs.They are a little more costly than the "Plus" bulbs I was looking for, but figured I'd take a chance, thinking that as long as they were as good as the "Plus" version, they would still be infinitely better than the standard bulbs; and money well spent.Well, they arrived (very quickly) and I had them installed in minutes (check your car's manual for details of how to change the bulbs) - I couldn't resist flicking the lights on after swapping out the first of the bulbs to see if the difference was noticeable as I was expecting. It was!With the second bulb in, it was time for the road test.These things are bright! VERY bright! They seem to light up the road for miles! Street signs become visible way before there are readable and the cats-eyes light up like a runway!I can't with any certainty say whether these are brighter than the slightly cheaper "Plus" version, but I like to believe that they are (if for no other reason than to justify the added cost!)I'm also not able to comment on the longevity of them, however if they are anything like the "Plus" version, they will last at least the next two years - I'll update this review if they pop before then.In short, I you are looking for something (legal) to throw (significantly) more light on the road, particularly over the winter months, look no further!I have also since replaced both the park lights and the main (dipped) beams with:Osram Cool Blue Intense 2825HCBI-02B W5W 12V 5W Twin Blister PackandNew Osram H7 Night Breaker Unlimited with up to +110% more light, 64210NBU-02B 12V 55W, Twin Blister of Headlight Bulbsrespectively - couldn't be happier!

This bulbs are definitely good improvement, compare to standard in my Mazda 6 2003 H1. Not so priced and advertised as X-treme Power, or Night barkers, but do a quality job, can see sharper spectrum it covers, obviously made in a high standard manufacture with proper geometry (filament of the bulb and etc). This bulbs provide white light, just very slightly yellowish, but not yellow, as standards. They are do the job on the wet surface too as they are not blueish,tried. Previously used in my cars Philips X-Treme Power, Night Barkers and Chinese xenon))). Doesn't know for how long they will last compare to night barkers, but suppose should last longer, as they are not so overheated. Definitely recommend, especially for the price as I got - about 9£ for two and on each it is stamped - made in Germany.

I bought these with a pair of H7 bulbs for my SEAT Altea's main and dipped beams. The original set up was awful and I do a lot of unlit country road driving as part of my commute to and from work. I'd looked into what upgraded bulbs were best and the Osram Night Breakers seemed to be the universal victors in numerous tests.I fitted them and they give a much whiter light than "standard" bulbs and the throw might be a bit further. What is noticeable is the patchy dark and light areas at the fringes of the beam. This might be a reflector thing that the old bulbs didn't highlight, but it's something that is very obvious now. With dipped and main on together, things are much brighter than before; those pesky pedestrians and cyclists that wear black while using the dark lanes at night are more easily spotted.A word of warning though. All the sales pitches for these state that they are far better at this and that. What isn't highlighted is that this extra performance comes at the much reduced longevity of the bulbs. "The light that burns twice as bright lasts half as long".A good replacement for ordinary bulbs.

As per the H4 bulbs I bought at the same time I bought these bulbs to replace a set of Osram nightbreakers ( Up to 100% more light). I did wonder if I would see any difference and was suprised to say that I think that they are putting a better beam out than the previous bulbs. I appreciate this may be down to this pair of bulbs being better matched ( Bulb reviews in popular car magazines often show a significant difference in bulb performance down to poor build quality) but I can see a marked improvement. At this price they are great value as the normal price is about as much again. A work colleague had noted the light intensity of the previous set which appears a brilliant white and this is the same for these items. Very satisfied.

If you do a lot of night driving then these lamps are an essential upgrade for your vehicle's headlights. I've been using these on my van for a couple of years now! I drive to and from gigs most weekends where it's not unusual to be driving on dark unlit country roads in the early hours. These really do put more light on the road!But... Please be aware that these do not last as long as standard brightness lamps. The filaments burn a lot hotter than usual hence the whiter and brighter light, much like that of a traditional halogen projector lamp. But I'm sure you will agree the extra brightness is worth the small sacrifice in more frequent replacements. Yes, I am a nerd! The difference is well worth it!For best results, always replace in pairs after the first lamp fails (usually the near side on my van, the access behind the headlight isn't great for the fat sausage fingers of a forty something wedding DJ!) as after the first fails, the other won't be far behind! Fit these and brighten up your night drives!
