Review: Simple et performant - Très efficace, je recommande
Review: Very good ‘bulbs’ - 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.

### ⭐⭐⭐ Adaptateurs Canbus non fourni
*by X***F on 8 September 2025*

Je recommande l'article pour sa qualité de fabrication. Le seul bémol : l'article n'est pas livré avec des résistances/adaptateurs Canbus anti erreurs - hyperflash.
