PHILIPSUltinon Pro3100 LED T10 car signalling bulb (W5W), 6.500K cool white

Ordered these for a 2011 Freelander 2 front and rear indicators. Perfect fit, very nicely made, and a good level of brightness without being blinding, but the bulbs flash at a very high rate when signalling. I believe the legal limit for the UK MoT is between 60 to 120 flashes per minute. These flash at at least the 120 max limit. To be fair, the listing says they will work 'with most vehicles', so perhaps they might be worth a try on your car as long was you are prepared to return them if not.

Work well. Nice and bright light. Will see if they last longer than the cheap ones.

Decent set of bulbs. I only really neede the one as it was for a motorcycle tail-light but they come in pairs, predominately for cars! Fairly bright but not so bright as to dazzle following vehicles. The brake light lamp being the brighter (obviously). I fitted it to an old classic Suzuki SB200 which is a 12V system but with a fairly small battery so I wanted to upgrade to brighter bulbs with less current draw. This seems to do the job adequately. Cleatly these are more expensive then typical bulbs but if they last longer, it’ll be worth the cost. Vibration kills most old bulbs on a vintage bike so hopefully an LED version should stay the course.

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.

Failed after 7 months.

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.

Great product, i could have gone to halfords and gotten a set and i did. They broke. So i went for these and haven't looked back. Ill be buying again for another position in my car. Great quality, nice light output colour that matches there led headlight bulbs, due to them being reliable good value for money,

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.
