OSRAM LED Premium Retrofit PR21/5W Interior Lighting - 1557R-02B, 12 V, Double Blister, 1 Unit

After going through numerous brands, heatsink variations, emitter type/amount of W5W bulbs I decided to pay a little more to see if I could finally find a set that don't die after a few months.After owning multiple OSRAM emitter flashlights these seemed like a good gamble, and it paid off as they're still going strong over a year later!They're a crisp white too rather than a lot of the very blue/green tinted led you can get.

Les LEDs clignotent lorsque de l'allumage de nuitLes deux stops sont OK lorsque l'on freineNe fonctionne donc pas sur ma C3 CAN Bus (ne fonctionnera donc pas sur les automobiles PSA en CAN Bus)

Niente da dire e onestamente non comprendo altre recensioni sul prodotto. Comunque, il prodotto è ottimo, la luminosità è pari alle alogene, il cambio dalla luminosità bassa (posizione) alla luminosità forte (stop) è perfetta e il colore rosso evita problemi con l'intensità naturale dei led.La resa è ottimizzata per gruppi ottici con parabola, quindi attenzione, perchè se di parabola riflettente non ci fosse traccia, allora queste lampadine non andrebbero per nulla bene. Nulla da dire poi per la qualità che è la solita Osram e quindi ineccepibile (garanzia di affidabilità e durata).

Tired of spending money on cheaper LED bulbs to replace the double filament P21/5W that work as both tail and brake lights on my car (1998 Audi A6 TDi), I was feeling I was going to have to return to filament bulbs as none would work properly. Some wouldn't change brightness as I pressed the brake pedal, others worked in reverse (super bright as tail lights, then dimmed as I pressed the brake pedal - not installed backwards, as the locating pins on P21/5W only allow one position).So, getting these was a sort of last resort. They're pretty pricey, VERY pricey for my budget. But I felt I had to give it a go before quitting on LED for tail/brake lights foverer.Well, very happy to report that these DO WORK as intended! The standard tail light mode is perfectly bright, not too much, not too less. and it fills the inner shape of the tail light without any shadowed areas.Then as I press the brake pedal, INSTANT bright light! So much better that filament bulbs, and the instant change in brightness not only looks better and more modern, but make it mode visible to anyone seeing it. Furthermore, the fractions of second gained in reaction time for those following you can mean the difference between getting rear ended or proceeding wittout an incident.The bulbs themselves are very heavy, much more that I expected. Looks like they're mostly made of very thick solid metal. Probably has something to do with proper cooling for longevity.Another thing is these are advertised as not being fit for on road driving, which is rather strange. They're bulbs that perform exactly as they should with no extra super bright light that could eve endanger anyone. I suspect not even once has a car failed an MOT for having these installed. They're well within standard brightness. The brake setting IS brighter than normal by about 50%, but that is an advantage rather than a problem.

Acquistate per sostituire la lampada dello stop originale della mia Clio III del 2007. NON sono Canbus ma sul mio modello senza controlli non ha segnato alcun problema! Acquisto consigliato!
