Philips Ultinon Access LED car headlight bulb (H1), ultra-compact direct-fit, 80%, 6.000K, set of 2

Was initially skeptical given the general negativity on retrofit LED headlight bulbs. Turns out they work brilliantly on a 2017 Renault Zoe ZE40, notorious for pathetically dim halogen headlights despite being a relatively new EV. These H7 bulbs work great in the car's projector headlight housings, throwing out crisp white light that actually lights up the road ahead. My projector lenses also keep the factory beam patterns so I do not blind oncoming traffic. Installation is dead simple. Literally plug & play in replacement of the original H7 halogen bulbs with no modifications or workarounds needed at all. Downside to these keeping the H7 bulb shape/size is that they do not get as bright as the other LED bulbs that are physically larger and sometimes come with bulky heatsinks. But from 2 months' use (Oct - Nov), I found them to be perfectly adequate for general road use. My car does not have any canbus or electrical system checks for its exterior bulbs so bulb errors is not a problem for me, and I cannot comment on these bulbs' error prevention or canbus circumvention ability.

I'm surprised by the difference these LEDs make compared to high-end bulbs. The light is really bright and cool. They fit perfectly, and they have the exact same dimensions as regular H7 bulbs. My best purchase of all time. You can really see the difference. Worth every penny.

Fantastic upgrade for the car. I’ve replaced the original bulbs for these bulbs on 3 separate cars now and it’s been the best upgrade I’ve done to them, they slot straight into the original bulbs holder. They are made from metal and very well made. They have a nice bright white light, and they are still going a year later so well worth the money. Not quite as bright as the LEDs you get on factory built cars with LED lights, but far far brighter than any halogen, so a good upgrade to a new car with little hassle or installing. It has made driving at night much more pleasant.

Easy direct replacement of original lamp, good light out put, far better than stock but with excellent beam pattern and a much better colour temperature than filament lamps. Despite being slightly larger, they fitted my units with no issue. Would highly recommend as an upgrade to very modern looking and function lighting to any older lamp type units. I have OBD lamp failer detection on my vehicle and no errors after 6 weeks of use. I have also used the H4 units with the same success.

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]

Would be a 5 but for .... CAN-Bus Issue The Upgrade: I recently upgraded the H7 dipped beam halogen bulbs on my 2005 Porsche 997.1 to the new Philips Ultinon Access LED bulbs (H7). * Purchase Context: Although a pricier option, these were bought on the basis of being a direct plug-and-play replacement for halogens. I noted that Philips markets some of its LED retrofits (like the Pro6000 series) as being road-approved for use in Germany (ABG approval), indicating a focus on compatibility/ safe beam performance. Performance (The Good News): The light output is excellent, offering a modern, cool white (6000K) look and significantly improving night visibility * The LED light pattern is exactly the same as the halogen bulb. This means oncoming vehicles are not blinded by the dipped beam, (the bain of night time driving,) while light penetrates much further down the road. Compatibility (The Catch ): The onboard computer OBD is throwing a "Check L dipped beam" and "R dipped beam" warning on the dashboard. This is a classic CAN-Bus error - the highly efficient LED bulbs (approx. 16W) draw significantly less power than the original halogens (approx. 55W). Diagnostic Detail (The "Why"): Warning only triggered when: * Turn the key to the 'ON' (Accessory) position. * Switch headlights ON (before the engine is running). Engine Running then Switch headlights ON (No Warning): Once the engine is started, the system enters normal operating mode. The continuous monitoring of the headlight circuits is reduced or disabled. The LED's current draw is within a broader acceptable range, and fault message is suppressed. In short, the Porsche's OBD is sensitive to the low power draw during its pre-running circuit check. The Solution: Purchase and install a set of H7 LED CAN-Bus Control Units / Load Resistors on both dipped beam circuits. These will add the necessary resistance to fool the sensitive pre-ignition diagnostic check current draw equates same to halogen. Or, Get in a habit starting that 3.6 litre flat-six engine **before** putting headlights on. ;-)

Best headlight bulbs I’ve ever had. Very bright. Way better visibility. No issues whatsoever. Happy days.

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.
