OSRAM NIGHT BREAKER LASER H4, halogen headlamp, h4 bulb, 64193NBL-HCB, 12 V passenger car, duobox (2 units)

Short review - excellent quality and easy install without touching the glass element. Nice crisp white light that look great though my St220 halogen HID headlamps giving the bluey glow. Gave me extra distance and slightly wider spread too. Nothing to write home about but noticeable for sure. Wouldn't go back to standard bulbs. They kick in quickly though I imagine some of that is to do with your headlamp set up and ballast igniters maybe? Have lasted me at least a year so far and no sign of glow fade yet

I was a bit dubious at first, purchasing anything other than OEM bulbs or from Halfords, but after reading far too many reviews online I decided to take the plunge - I'm glad I did.The Nigh Breakers from OSRAM stick up to their reputation, after replacing them I could see noticably further on the road and felt a lot safer driving as a result. Comparing the Amazon price to the equivalent own brand or OEM bulbs from Halfords, the fact they're speced to only last half the time didn't phase me either, if I'm getting double the light for the same price as in Halfords, I'm on to a winner.I was weighing up between the Bosch and decided on these, I would certainly just go for it, you won't regret it.

Excellent bulbs. I have a little Daewoo Matiz which has very old light plastic that I have to polish up once in a while to make it clear again. It helps to have more powerful lamps in now, much brighter and crisper than the other Osram and generic bulbs I previously used. My car's lights are definitely dimmer than the average car on the road as I'm constantly being dazzled by them, but at least now if I drive on a country road it's a bit less nightmarish and the light is whiter and easier to adjust to than the yellow I had before.

Great value for these 'Night Breaker' bulbs, which happen to be very well named. I got these to replace the bulbs in my 18-year-old Mazda Bongo Japanese import day van. The plastic headlight lenses yellow with age, and even after refurbing the headlights aren't the greatest on the road (certainly not compared with more modern vehicles). These arrived next day on Prime, and I was happy to pay a couple of quid more than some parts factors sell them as it saved a journey or paying similar with delivery but without the same no-nonsense returns you get using Amazon Prime if something is wrong. Anyway, fitted these in 10 minutes including having a cup of coffee half way through and can now not only see the road ahead a lot better on my 5 am drives to work, but any other early birds on the road can see me coming as well...

Bought these for my daughter who is a relatively new driver and does not like night driving as her standard lights are poor.Fitted these and pleased to say she has found the lights better, with the beam going further, judging from her increased night driving on her tracker, would say they have made a difference ( from a parent point of view perhaps should have left the old bulbs in ...lol)Not been fitted that long so do not know how well they would last.From my own personal experience (over several different brands )found you get what you pay for with bulbs and the higher performance ones tend to be more fragile and don't last as long perhaps as they burn hotter?Now fitted these to my other daughters car, again reported improvement in light coverageWould recomend

Good quality bulb and very bright. Not cheap but worth it. My go to bulb and I fit them in every car I keep for any length of time.

I installed these bulbs in my Honda CRV. It's an old car (2002) that I use for my daily commute which involves lots of unlit country lanes in Hertfordshire. The factory bulbs were dreadful and while researching better bulbs I found myself in Halfords. They had their own brand bulbs on sale for £4 each so I thought I would give them a try. They were an improvement over the factory bulbs, whiter and a bit brighter. I then decided to buy Osram Night Breaker Laser bulbs thinking I would get a further improvement. I have to say that the difference between the cheap Halfords and these Osram bulbs is negligible. Yes slightly brighter (my guess 10% at most). I will be trying some LED bulbs next.

I replace my headlight bulbs every winter as they degrade (not fail) after about a year as they are overdriven to get the maximum amount of light out if them. These are very good and give a good light and colour. I've used all of the major manufacturers high output bulbs and I can't tell the difference, they all work and last about as long as each other, but these are very keenly priced, I think Halfords want about 3 times more for the same bulbs!
