Always have spare lamps:It is strongly recommended to equip yourself with an emergency box or spare lamps in order to always have the right lamp at hand in case of failure of one of them. This ensures safety and compliance with legislation. |
Respect basic precautionsTouching the glass of the bulb with your fingers may shorten its life. When replacing the bulb, use gloves or a soft cloth to handle the bulb. - Be careful of the risk of burns if you change a bulb that has just worked. The gloves will be your ally |
Remember to change your lamps in pairs:Since the lifespan of two identical lamps is extremely similar, it will not take long for your second lamp to stop working. Your safety will be compromised. Whether you change your lamps yourself or by a professional, it is more convenient and economical to change both lamps at the same time. |

There was a problem filtering reviews right now. Please try again later.
These bulbs from now on are my favourite until something exceptional comes up.
So if you are like me unsure of what to buy as the market is flooded with hundred of bulbs look no further.
Pros: Perfect beam cut off, Very bright, beam range 75 -80 m and bulbs are cheap.
Cons: Cannot say anything till yet, may be the packaging is not that fancy in comparison to other bulbs.
I would highly recommend these bulbs.
There was no discernible beam pattern, instead of which both headlight simply gave out splodges of random light which illuminated no further than about 4 or 5 metres from the car.
I know that it wasn't caused by a problem with either my headlamp assemblies or electrical system because once I stopped and replaced both bulbs with another make, the headlights performed as expected.
The 2 photographs (snapshots from my dashcam taken on 2 subsequent nights at the same location) show the difference between these bulbs and the Osram bulbs I replaced them with.

These have replaced a pair of
Osram Nightbreaker lasers which have a very short life span.
Sooo... in the same car, these prove to be much brighter with a longer beam. I would however dispute the claim of a white light. They are pretty standard in my opinion.
I can’t vouch for longevity as I’ve only just fitted them. This is where I’ve also seen complaints in other reviews. No high performance aftermarket bulb will last as long as a standard one. It’s a bit like complaining that a Ferrari uses more petrol than a Ford Fiesta. There has to be a compromise somewhere if more performance is demanded.

Slightly less yellow than my old tired Philips H7 bulbs (kept as spares).
No strange light distribution that can happen with super-budget no-name bulbs.
Slightly better lighting of road, but probably no different to new basic Philips H7's.
Cannot comment on life / longevity yet.
Bought these after 2 disastrous purchases of so-called 'best buys' lauded by a certain weekly car magazine.
Despite being half the cost and 'only' +90's - These are very bright or maybe the light is just going where it's supposed to when compared to +130's and +150's I have been using.
I've been using these for the last 6 months which is aleady 6 times longer already than the more expensive others!
Will buy again when needed... :-)
They are well and safety packed. They have really bright and strong and white light beam and difference in color is visible comparing to the light below them. I have them for few weeks and works with no issues, hopefully they will last for long long time. For this price I think it’s one of the best choices.
