Rated 3.7 out of 5 by 24 reviewers.Rated 4 out of 5 by Oldfella59 Good product These bulbs were bought to replace the ones in my Mini Cooper Clubman,which were ok,but lacking in density directly on the road in front.The new Halfords bulbs filled this area in very well.And the BOGOF deal at the time made this a great purchase.Now bought a set of H7 for the wife's 12 year old Mini. 26 January 2016Rated 4 out of 5 by BrenUK First Impression I am writing this review because a number of reviewers claimed they were no brighter than ordinary bulbs. Well they are certainly brighter than my previous bulbs. Other reviewers may have had very bright bulbs before changing them but didn't realise it, OR, they don't understand the subject rating of brightness. Twice the physical light output does not translate to twice the subjective assessment of brightness. Unfortunately, the English language does not provide an adequate vocabulary for this and "twice as bright" has been made serve for twice as much light. Strictly they should have claimed "up to twice the light output" Most people are familiar with sound: Twice the sound level means twice the energy measured in Watts and related as a 3dB increase. If you play your stereo system in mono mode so that both speakers are producing the same sound and then compare how loud it sounds with 2 speakers running to how loud it sounds with 1 speaker running you will have halved the acoustic power but it will not sound half as loud. One dB change when listening to music is just about noticeable in a controlled laboratory-style environment (otherwise very quiet room) whereas in a practical situation (say a busy café) 3dB is barely noticeable. Subjectively, people tend to say twice as loud for a 10dB increase, which is ten times the power output. Technically, this is a logarithmic scale and is typical also for subject response to lighting levels. Night driving on an unlit country road is equivalent to being in a quiet room. Also remember that light (an sound levels) fall off as the square of the distance. The light level is halved when you increase range by 41% Most people are able to continue driving normally (illegally) if they lose one headlight but the range for equivalent illumination levels drops by ~29% to ~71% of the previous range. I hope the negative reviews about longevity are exaggerated. If these bulbs last less then 2 years I will update/complain. 10 December 2015Rated 2 out of 5 by rondo69 Short Life Span These bulbs do an adequate but not brilliant job. I am on my 6th replacement Halfords Ultra Brilliance side light bulb on my Volvo since April 2013. Before anyone makes a comment about touching the bulb glass, I haven't. In fact the first two were actually fitted by Halfords. These are just poor quality and you can see from the other reviews that I am not alone in saying this. I have noted when these last 2 failed (both within the last few weeks) and will add another review when the next one fails. But I will not buy the same again, in fact I should have bought another make last time. A great shame Halfords. 30 November 2015Rated 3 out of 5 by MCMc01 Bright but not very long lasting. These bulbs are brighter than standard bulbs although for the price I would expect them to last longer. Less than 9 months and they've blown already. Was told by a staff member that they have no real warranty on them. 06 November 2015Rated 4 out of 5 by scirious2 Mixed feelings... These are no doubt brighter than standard lamps but they're not as good value for money as Osram Night Breaker Unlimited lamps which may be obtained for less money. However those reviewers who claim no improvement over standard lamps must be trolls as the difference is obvious. As to their longevity....time will tell. But increased intrnal (envelope) temperatures generally mean shorter life. 16 January 2014Rated 5 out of 5 by FUSSYGUY MY JEEP LOVES THEM EVEN THOUGH JEEP CHEROKEE HEADLAMPS ARE 7" DIAMETER THEIR OUTPUT IS VAGUE AND YELLOWISH. SO, TODAY I FITTED A PAIR OF HBU472UB. TESTS TONIGHT CONFIRMED THESE ARE REALLY BRIGHT AND OPTICALLY WELL CONTROLLED. THEY THROW THAT WHITE XENON COLOUR. (DIVERS USE XENON LAMPS) THANKS TO THE LADY STAFF MEMBER AT STEVENAGE FOR SUGGESTING THEM. FUSSYGUY. 24 October 2013Rated 5 out of 5 by chappo49 Ultra Brilliance Bulbs Replaced these in my daughters 1999 Peugout and now the unlit road ahead is lit up with white light rather than a dim yellowish light. Much safer all round. 11 October 2013Rated 4 out of 5 by Aladdin786 Ultra Brilliance Car Bulb Much brighter than normal headlights - brill! not quite 120% but without a doubt much much brighter. 06 March 2013
