## Questions & Answers

**Q: Is it really 150% or 50% brighter? (this is question to philips I think)**
A: The measure of brightness is probably marketing BS. What you're looking for isn't really peak lumens but what's called a figure of merit measurement. This sticks the bulb in a typical reflector and measures how much light goes where you want it to go. You might have a really bright beam but if it's illuminating the wrong place then it's bloody useless. The interaction with the reflector depends on a few things (such as that lovely silvery bit on the end which will reflect and block light). I really dunno what they have based their measurement on but you can be damned sure it'll be in completely ideal conditions when magical fairies happen to be farting in the direction of the northern lights or something. From quantitative testing in experimental conditions I can say these are the best using FOM and using the reflector employed during testing. Osram's top of the range bulbs came a very close second and probably within the margin for error of the testing. Compared to the FOM measures of an OEM bulb (various makes, they're all various levels of shite) the result for this was some 3 or 4 times higher. Basically this is brighter overall (which means you MUST ensure your dipped beams are aimed right - easy to do with a wall or using the car in front in stopped traffic and the little adjuster in the cockpit) and put more light where it needs to be on the road. You will be able to see the outline of the projection of the reflector with these things (i.e. a spike on the left hand side to illuminate road signs and then dropping down where it hits oncoming traffic so as not to blind them) which you have no chance of seeing with stock bulbs unless you have HIDs. On the subject of HID - I fitted a HID kit (an expensive one, not crap) to my motorcycle and after technical issues I removed it and replaced it with one of these high end bulbs. The end result was 90% of the efficacy for about 20% of the cost. Hope this helps.

**Q: are these bulbs main/dip in one bulb**
A: Yes the bulbs are main and dip in one bulb. They are a whiter light than original. Certainly brighter.

**Q: Are these bulbs UK road legal**
A: No, these are not legal, if you want a light upgrade, go to a main dealer and ask about a xenon light upgrade. Car lights are special designed for a certain bulb, upgrading a bulb is dangerous as it can cause unnecessary glare to on coming vehicles. Which is why Mot centres do not pass these upgrades.

**Q: How long should they last? I fit them in april and one bulb has already blown**
A: Bulb life will be compromised if it is soiled  when fitted. Make sure the next bulb is spotless and dont touch it with you fingers

## Customer Reviews

### ⭐⭐⭐⭐⭐ The best bulbs I have used.
*by S***N on 4 October 2020*

I replaced the bulbs in my other car last year with these and should have done the same with the Focus. The lights were perfectly adequate but then 1 bulb went and I just bought an ordinary bulb from the garage and didn’t really notice any difference. Then some weeks later the other dip went so I replaced that as the first. It was then I realised how the light output had deteriorated. So now I’m on the same as the other car and can see at night again. I never get flashed as they are set right and must have a decent cut off. I’m expecting the longevity to be good because Phillips a good make.

### ⭐⭐⭐⭐⭐ Please read before purchasing!
*by K***T on 14 January 2017*

This is probably the first time I am writing a product review. I am passionate about cars and safety is one aspect I do admire. Therefore, I decided to change the standard headlamps to these Philip racing vision ones which are 150% brighter and totally road legal. They certainly give the car a very good look especially pleased me even though I had high expectations. The bulbs are 55W and totally legal. They don't have that much difference on normal street lighted roads. However, if you travelling on darker roads or on poorly lit roads this does wonders. Overall, don't be mistaken that you will see more powerful lights. They are more brighter with the same intensity and they reach out further and have better clarity on darker roads as the light is more on the whiter tone. This will help all customers to understand this product better and manage their expectations which would otherwise lead to negative reviews for a great product.

### ⭐⭐⭐⭐ LONG TERM REVIEW: Works great, until it doesnt...
*by S***. on 30 September 2022*

LONG TERM REVIEW:Bought a 2 pack of these bulbs in early 2019, to replace a nearside bulb. The light is good, a bright white (rather than the OEM fit warm(er) white), and visibility is good.However, yesterday the bulb stopped work (the filament has split). Happily, with the remaining bulb from the multipack I could replace it. But in that time, the bulb on the offside has continued to work perfectly - which I assume is the factory fit bulb.So, the bulb is great, but the longevity could be improved. Whether the 'racing' design of it makes a difference to longevity or not, I'm not sure.
