PHILIPS Ultinon Pro3100 LED car signalling bulb (W16W white)

I used these as a replacement for the frankly woeful reversing bulb in a 2014 SEAT Leon FR (5F).You only need one bulb and it’s a 5 minute job. It did not fling up any error message on my dash but I would suggest coding via OBD Eleven or VCDS to LED bulbs just to be sure.Overall difference is both very noticeable at night and during the day,with visibility substantially increased over the OEM alternative. I used to have to rely on my LED tails to know where I was.For the price, ease of fitting, performance and lack of error message I can’t recommend these bulbs enough.

Used these to replace W5W lamps on my motorbike. There are many unbranded/unknown brand LED W5W versions available but they are variable quality and don't last well, don't fit or give poor colour performance. These Philips lamps are much higher quality, as you would expect from a major lighting brand. They fit very nicely and provide very good light output and colour. Life expectancy is yet to be known but I am confident that they will last much longer than the cheaper types.

Bought these as an upgrade for my wife's Scirocco. Lood good in the drl housings, however they show on the dashboard as having 2 blown bulbs even though they are working. I have replaced a lot of her other bulbs with LEDs and not come across this problem

Not compatibile with Hyundai Getz and BMW E87. Hyperflash in both cars. I just waste my money.

I bought those as one of the, day time running lights (DRL) stopped working. Glad I went with those they are nice and bright the picture does not show the true brightness of the light output. They are fitted to a vauxhall zafira tourer 15 plat. I would definitely recommend those to anyone looking for a new DRL and its a nice little upgrade in terms of the light been a crisp white. Another top product by Phillips. I will update the review once I find the longevity out to match the current 5stars.

The bulbs are of decent build quality, good colour and brightness. The bulbs themselves work ok but you get the dash indicator arrow hyper flashing when you apply the indicator. I believe these have not been updated to work with canbus in modern cars, may work ok on older cars. Ok value for money if they work and they fit without any issues.

I bought in the hope of a slightly brighter indicator light, and it achieves that. Not too bright to be silly, just that extra edge.What I hadn’t appreciated though was the additional benefit of a more distinct signal. Seeing a standard incandescent bulb side-by-side to this LED highlighted that the incandescent bulb doesn’t actually quite go out. The filament gets hot and the brief moment the power is off doesn’t give it chance to fully cool to nothing. The LED on the other hand is instantly on then off, making a more distinct, and hopefully noticeable, signal.Do note though that on some cars, my 2014 RAV4 included, you will need to increase the resistance in the signal circuit otherwise you will experience fast flashing, hyper flashing. That is just because the LEDs draw less current than their incandescent equivalent and you need to add a resistor to mimic the original load. I went for the Osram LED driving 21 watt version as a respected brand. Whilst I only changed the rear indicator bulbs for LEDs I add the resistors to the front indicator wiring as it was easier to access and allowed me to mount the resistors onto readily available metal brackets in the engine bay (that they need as they get hot!).I’m very impressed! I’ve got other Philips LEDs in other lights around the car and they’ve lasted years, so I’m confident that these will do the same.Well done Philips, another great addition to car safety.

Easy to fit plug and play

Para matrícula..Luz blanca de calidadNo muy potentes

Très belles ampoules led, s'adapte parfaitement, aucun soucis de fonctionnement.

Usate come stop e posizione per il mio scooter, lavorano molto bene. La luce emessa é buona e ben visibile a lunga distanza. Per ora a tre mesi dal montaggio sono ancora perfettamente funzionanti.Spedizione puntuale come sempre.

Erreur canbus

They provide good light but cause canbus issues.
