I was initially slightly wary about paying £15 quid for a couple of LEDs, especially as they are only to replace my sidelights; I have no regrets. The finish of these lights are good quality. Unlike the bulk made China bulbs you can get left right and centre on both desertcart and Ebay, this offering from OSRAM feels well made. They are fully plastic, and there is a transparent but frosted covering over the LED chip itself to disperse the light produced. Installation was a breeze with polarity not being an issue thanks to the design. For me at least, the installation consisted of literally a straight replacement from halogen to LED. No errors or warnings of any kind - they just work. The colour of the light from these lights is great too. They aren't yellow, but they're not pure white either - a nice balance between the two. There also doesn't seem to be any blueish tinge which made me happy, as I don't like that. They are a huge improvement over my old halogens which were basically a waste of time. I've had a test drive behind my partner in a separate vehicle and there is no glare at all, just better presence on the road. For me these LEDs have changed my barely visible halogen sidelights into what are essentially very useful manual DRLs. I highly recommend them to anyone looking to replace their halogen sidelights. Review: a massive improvement. Not "boy racer" at all. - Works really well, transforming my weedy Orange, distinctly 1990's style, bulbs in to a much more modern style. The colour is White and doesn't look like the Blue ones used on cheap lowered BMW's with overly bassy stereos. The bulb emits much more light than standard and could be perceived as safer as a result. My only problem was, I had just these side lights on, In my garage, at dusk and I absent mindedly mistook the high emittance for the headlights. I drove off without my headlights on but the light was so bright no-one noticed. Fitting these, depending on your application, can be awkward because the bulb is so small, it is easy to accidentally touch the bulb. Just wipe the bulb with meths if you do, the oils from your hand can shorten the life dramatically. ## Features - Up to 100% more light than a standard bulb - 6000K Cool White Daylight colour appearance - Up to 80% more environmentally friendly than standard bulbs - Latest optical diffuser material gives the best light performance - Update your bulbs and add some brilliance to your car ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0088XET0S | | Auto Part Position | Inner | | Automotive Fit Type | Vehicle Specific Fit | | Best Sellers Rank | 170,375 in Automotive ( See Top 100 in Automotive ) 864 in Automotive Turn Signal Bulbs | | Brand | OSRAM | | Brand Name | OSRAM | | Color Temperature | 6800 Kelvin | | Colour | white | | Colour temperature | 6800 Kelvin | | Customer Reviews | 4.6 out of 5 stars 2,530 Reviews | | Fit Type | Vehicle Specific Fit | | Global Trade Identification Number | 04008321657657 | | Item Type Name | OSRAM light bulb | | Item Weight | 0.02 Kilograms | | Item package quantity | 1 | | Light Source Type | LED | | Light source type | LED | | Manufacturer | OSRAM | | Manufacturer Part Number | 2850CW-02B | | Model Number | 2850CW-02B | | Number of Items | 2 | | OEM Equivalent Part Number | OSRAM LEDriving LED Retrofit W2.1x9.5d per illuminazione interna 2850CW-02B Cool White 6000K 80 minor consumo di energia - in Blister doppio | | Package Quantity | 1 | | Part Interchange Info | 501 | | Specific Uses For Product | Interior Light | | Specific uses for product | Interior Light | | Unit Count | 2.0 count | | Voltage | 12 Volts | | Wattage | 1 watts | ## Product Details - **Brand:** OSRAM - **Specific uses for product:** Interior Light - **Item package quantity:** 1 - **Colour:** white - **Auto part position:** Inner ## Images ![OSRAM LED Premium Retrofit W2.1x9.5d, LED-W5W, interior lighting, 2850CW-02B, cool white, 12 V passenger car, double blister (2 Unit) - Image 1](https://m.media-amazon.com/images/I/71+Z1xvFyAL.jpg) ![OSRAM LED Premium Retrofit W2.1x9.5d, LED-W5W, interior lighting, 2850CW-02B, cool white, 12 V passenger car, double blister (2 Unit) - Image 2](https://m.media-amazon.com/images/I/618UIdZKutL.jpg) ![OSRAM LED Premium Retrofit W2.1x9.5d, LED-W5W, interior lighting, 2850CW-02B, cool white, 12 V passenger car, double blister (2 Unit) - Image 3](https://m.media-amazon.com/images/I/61P+i+NzPZL.jpg) ![OSRAM LED Premium Retrofit W2.1x9.5d, LED-W5W, interior lighting, 2850CW-02B, cool white, 12 V passenger car, double blister (2 Unit) - Image 4](https://m.media-amazon.com/images/I/611kjQRchzL.jpg) ## Questions & Answers **Q: what bulb do they replace on the car?** A: These bulbs will replace the following applications: 168, 194, and also 921 with some minor modifications. 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect replacement for my old halogen sidelights. *by G***R on 10 January 2016* (Ford Focus Mk2) These are some good bits of kit from OSRAM.

These are well made, cast a nice bright and diffuse light, are very efficient, run cool, and should last for years. Good replacement for 5W interior lamps if you want a brighter looking whiter light. The 4000K doesn't quite reveal the colour balance - it's not quite a neutral 4000K. It has hints of pinks and other colours in the mix, but overall a pleasing white-ish colour. For (unauthorised) use as sidelights they wont quite match the (also slightly coloured) appearance of 4300K original equipment HID headlamps, but they're closer than anything else I've seen and would look much nicer than using regular filament lamps, blue vision type coated filament lamps, or any of the other not-strictly legal LEDs that are usually way too yellow at 3000K or way two blue/violet 5000-7000K. They may not meet Construction and Use Legislation but would be unlikely to fail an MOT as things stand. ## 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.tn/products/47907393-osram-led-premium-retrofit-w2-1x9-5d-led-w5w-interior](https://www.desertcart.tn/products/47907393-osram-led-premium-retrofit-w2-1x9-5d-led-w5w-interior) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-02*
