I have them installed in my license plate, dashboard, and reverse lights in my 98 Toyota Corolla. I love them. **Q: Are these canbus free error?** A: There are very limited can bus leds if you use these for a blinker you would still have to add a resistor if you plan on using these lights in your car such as a dome light they will be fine can bus is used mostly on exterior lights blinker, tail light, running/parking lights. Hope this helps. **Q: Is this considered as a T10 also?** A: Yes it is T10. **Q: how many lumens?** A: Osram and Sylvania does not label their product led lighting with a lumen information--only wattage amount. The 194 and/or168 led light was placed in the interior fixture of a vehicle. It was guess work as to how much this light would produce. This light is a white-blue (5000K) that is almost twice as bright as the original incandescent light bulb. This light worked for my interior lighting. Lumens on the packaging would be of benefit. Manufacture engineers are aware of heat build up in the light which can shorten the life of the light against the light output of bulb. Heat is a killer for led bulb electronics. Thus, very high lumen lights can have a short life with a lot of heat retention. ## Frequently Bought Together - OSRAM LED Premium Retrofit W2.1x9.5d, LED-W5W, interior lighting, 2850CW-02B, cool white, 12 V passenger car, double blister (2 Unit) - OSRAM LEDriving® HL Gen2, ≜H4, LED High/Low Beam Lamps, Off-road only, non ECE, Folding Carton box (2 units), white --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/1894056-osram-led-premium-retrofit-w2-1x9-5d-led-w5w-interior](https://www.desertcart.jp/products/1894056-osram-led-premium-retrofit-w2-1x9-5d-led-w5w-interior) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-03*
