Philips Ultinon Access LED car headlight bulb (H4), ultra-compact direct-fit, 80%, 6.000K, set of 2

Ok first thing to say is that nowhere did it say these are Canbus error free so I was expecting a fault to show.... and it did...On my car that is no big deal. Start the car, error msg "low beam failure" pops up.. press the "ok" button on the stalk and its gone. No engine management light at any time and a one second fix. At some point I will probably buy the philips canbus corrector but at around £30 Im in no rush.Next the important part. Performance. Very very easy to fit.. bulbs have instant start up when switched on. The beam pattern is identical to the nightbreaker bulbs they replaced as far as I see. My car has projector headlights. The beam spread is more even and solid to my eyes. Driving with them is an altogether better experience over halogens. They light up road signs without the reflected glare of halogens. They illuminate the road in a more effective way for me. They dont appear "brighter"than halogens on the road surface but the white beam colour is far better at picking out what you need to see in my opinion. Its easier on the eyes.The cut off on the beam is spot on and no way a problem for oncoming drivers.My headlights look great and these bulbs have transformed my car to looking more modern and clean. If they last the 1500 hours promised they are well worth the money over nightbreakers. I shall be buying the H9 for main beams next. Yes I know they are not "road legal" in the UK .. and if they were in anyway inferior to halogens or posed a problem for blinding other drivers they would go. They dont.. they work brilliantly.. they are better than halogen and for me represent a safer drive. I will switch them out at MOT time.I have not driven them in rain or snow as yet but expect they will deliver the same quality performance.

It's a minefield trying to upgrade to LED bulbs, so many choices from a flood to the market of horrible quality items, I thought it was important to get a brand name. I dont know why this doesn't average 5 star, but from what ive read people are upset that they aren't road legal technically in the UK, or, I can only assume they are installing them the wrong way (there is a right and wrong way)To that, the LED diodes need to be face left and right, NOT up and down. You want the beam to be spread, which should be obvious.No, they aren't certified in the UK, but for how easy they are to install, if youre that concerned, swap out to standard halogens come MOT time.The performance; they actually transformed a MK3 Fabia with projector headlights, from being so poor at night on standard bulbs that I didnt want to drive at night, to being nearly as good as a 2019 A6 and 2024 Kamiq we also run, both of these cars have factory LED headlights, and while I wasn't expecting this, these Philips LED's are comparable to those. Maybe not quite as sharp of a beam cut-off, but the throw of light is nearly as good.No error messages either, I wasn't expecting that either. I thought id have to plug in VCDS or similar to permanently remove the error, but there are none, at least in our Fabia, so im assuming any VW group car of a similar era would be okay also.The fitting is just the same as a normal bulb, no bulkier. These are also really good value, I just cant speak for their longevity or reliability, only time will tell. They do seem very well made, so the signs are good.

Nice, easy fixing and good brightness 👍

These, LED-HL Ultinon Access - for HB3 or HB4 lights. Don't! Just DO NOT.This is about specific fit HB3/HB4. My review can't work for any other fitting because each fitting is, very obviously, different in design and material and, who knows, might fit perfectly.HB lamp types are the L-shaped bayonet types. I bought a pair for a 2000 Toyota which has both HB3 and HB4 lights in lamp unit, as in, main and dipped beams require separate bulbs.Each bulb is assembled from two separate pieces, bayonet collar and bulb assembly.The collar is supposed to 'lock' to the lamp unit and then the whole thing bayonets into the fitting as one piece, like a regular filament bulb - in desperation I did try the pieces separately. The locking collar, a stressed piece, is made of a very nice, incredibly soft, flexible plastic. It does not lock in because it bends round the lock lugs that are supposed to be the 'locks'. The lugs look a bit small.I never managed to 'lock click' and confirm correct fitment.My best success was to have bulb stay in limply. Mostly I could wiggle it out.I could spin bulb round and round, lock collar zipping past locking lugs.The old bulb are back in.I don't think I did anything wrong - if so then a usable manual might have set me right.I don't see how this was ever sold.The eco-instructions are just as insulting. None in the box of course.No need to consult paper instructions whilst working on a car, good thinking that.I eco-downloaded the eco-instructions and found them as useless as the bulbs themselves.It's just a wishfully thinking brochure about what might be happening to some imaginary bulb THAT FITS.This review is specific to the fitting. I bought same brand, different series for H7/H18 and those look usable [I can't say more than that as I ran out of daylight doing battle with a light bulb. And losing]

Brilliant upgrade from h7 halogens on a 2006 range rover sport. Make a noticeable difference in light output, very clean and bright, but won't dazzle other drivers.Wish more mainstream companies would so them.Only negative is they are very expensive, unless you can get them during a sale or with a promotional voucher...planning on upgrading the high beam to them too 👍Highly recommend either way 👍
