Maybe a year from now I can, but I honestly expect to last several years, not just one. As for ease of installation, well that is more a reflection on the vehicle manufacturer than it is the bulb manufacturer. Remove 4 phillips head screws, remove the third brake light lense cover, and there's you bulb. Pop out the old, pop in the new, and put it all back together again. The bulb is much brighter than a conventional bulb, and requires less power to do so. I also like the flashing effect. It flashes a few times then goes to solid and stays solid until you release the brakes. Once you apply the brakes again, the process repeats. The whole reason third brake lights came into existence was to get drivers attention, and alert them you were slowing down or stopping. Now that they have been out 20-30 years, drivers are getting complacent again. This light flashing brightly a few times before going solid red helps get their attention again. I don't want anybody hitting me from the rear, or any direction for that matter. I think these bulbs are a great safety addition to my truck. If it helps prevent one accident, then it was worth the price...and I might add that these two packs of bulbs were pretty cheap to begin with. I hear they are illegal in some states, so you might want to check your local laws before you buy if you want. Me personally I don't care if they are legal or illegal... I am using them anyway. if some cop decides to write me a ticket for having them installed...well I'll take it, but they will remain. I like these bulbs and they serve a good purpose. ### ⭐⭐⭐⭐⭐ Increased Visibility *by on Reviewed in the United States February 16, 2024* Increased Visibility: The FANTELI 912 921 LED Bulb significantly enhances visibility, especially as a third brake center high mount stop light.

I highly recommend it for anyone prioritizing safety and visibility while driving, particularly at night ### ⭐⭐⭐⭐⭐ Perfect, ultra-bright safety upgrade for my 2014 Ram 1500! *by on Reviewed in the United States June 23, 2026* ​I bought this FANTELI LED bulb to replace a burned-out factory high-mount third brake light on my 2014 Ram 1500, and it is a nice upgrade.It is bright and way more noticeable than the incandescent filament bulb it replaced. Because the light itself emits a brilliant red (instead of the white of the old bulb shining through a red lens), the color is a much deeper and richer red.​It provides great eye-catching safety; when you first hit the brakes, it rapidly flashes three times before staying solid. It instantly grabs the attention of drivers behind you, alerting them that you're stopping.​One thing to keep in mind for Ram owners: the truck's "bulb out" warning system does not recognize the low power draw of the LED light on its own. To fix this and clear the dash error, I had to order and install a Diode Dynamics inline plug-and-play resistor.​The bulb itself is a direct replacement for the stock 921 bulb. Combined with the inline Resistor it is a nice modern upgrade. ## Frequently Bought Together - FANTELI 912 921 LED Bulb, Strobe Flashing 3rd Third Brake Center High Mount Stop Light, 300% Brighter Non-Polarity T15 906 904 902 W16W Brilliant Red - FANTELI 3157 LED Bulb Flashing Brake Lights, 300% Brighter 3156 3047 3057 3457 4157 4057 Plug and Play Strobe Blinking LED Stop Tail Lights, Brilliant Red - AUXITO 912 921 LED Bulb for Backup Light Reverse Lights High Power 2835 15-SMD Chipsets Error Free T15 906 922 W16W Bulbs, 6000K White Daytime Running Lights (Upgraded, Pack of 2) --- ## 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.fi/products/346808861-921-2835-21-red](https://www.desertcart.fi/products/346808861-921-2835-21-red) --- *Product available on Desertcart Finland* *Store origin: FI* *Last updated: 2026-08-28*
