OSRAM LEDriving® SL, ≜ W21W, Red, LED signal lamps, Off-road only, non ECE, Double Blister

The Osram W21/5W LED bulbs are excellent! They provide bright and clear light, significantly improving visibility. Easy to install, energy-efficient, and long-lasting, they’re a perfect upgrade from standard bulbs. Highly recommended for anyone looking to enhance their car’s lighting.

They have a similar brightness level to standard halogen bulbs while looking more modern, and should hopefully last much longer. One minor issue though is that they didn't work at first, until I used a screwdriver to bend the metal contacts in the bulb holder to make a better connection. They've worked flawlessly since. My car doesn't have CANBUS detection so I don't have to worry about that, but looking at other reviews it seems they would trigger errors if it did.

I'm at a loss to understand how these can be quite so bad. I have bought a lot of Osram bulbs and they're generally great quality. Something seriously amiss with these ones however. The 5W "tail" performance is shown in the photos. You'll see I took the bulbs out of the fitting for one photo as when in the fitting it looked like it's not actually lit.The comparison pic shows the normal incandescents on the left and the LEDs on the right. These were taken on the same manual camera settings. Both are much brighter than in reality. I could have adjusted to look more like reality, but I didn't want to alter the photos. So although the incandescents look just a bit brighter, in practice the difference is much greater as shown by the shot with one of each bulb type in the same light fitting (incandescent left, LED right).The other issue is that the 21W circuit (i.e. the "stop"/brake light part) was very intermittent. This was due to the bulb base being slimmer than a standard incandescent. They're basicaly a bit loose in the fitting and the brake light circuit contact was not intermittent. It might be possible (although not easy) to bend out the bulb holder contacts a bitto make them a more snug fit, but I didn't want to risk breaking the bulb holders and it shouldn't be necessary.They may be OK in some applications and it's possible other bulb holders might suit them better, but I can't recommend for a stop and tail light. I was looking for a brighter light and faster reaction for the brake light. While it does light faster (when I can get it to light at all), both the tail light and the brake light are dimmer than incandescents and so plain dangerous.

Took a chance on these as nowhere in sales description is canbus mentioned... but pleasantly surprised to see on back of packaging it says Canbus compatible... and they are.. well for a Volvo C30 anyway. The bulbs are very nice. Not too bright (photo exaggerates effect) and a classy upgrade thats looks pretty much OEM. So pleased with these am now going to try the Osram 21w led version for my reversing lights which need an upgrade. Hoping they last as long as Osram say.

Great product, works as expected in my 2017 Trafic X82 for DRL's. No Canbus issues.The light is nice, bright and white

Technically perfect, CANBUS compatible so no errors on dash. However not greatest for my use scenario - I have used them for wing mirror indicators in Volvo V70 III and it is not the brightest I have to say.Light looks more focused and not dissolved through reflective surfaces of the indicator, which kinda makes sense with them being LED.

Ótimo produto, ótimo brilho.Instalado em um UP TSI 2019.Não acusa erro e não precisa instalar canceler.Recomendo!

Arkadaşlar CANBUS sistemli bir aracınız varsa uymuyor haberiniz olsun. VW grubu araçlarda çalışmıyor. Lakin ambalajlama, kargo süreci ve ürün kalitesi mükemmel.
