After failing a state inspection on my 2004 Jeep Wrangler due to a bad 3rd brake light, I made a quick trip to Advance Auto to pick up this Sylvania Part No. 921 ST bulb. It was difficult trying to find the right part number I needed from their website. So, I double checked at the counter. It was quick and easy to replace using a Torx T15. The cavity of the brake light was filled with water. I dried out everything, replaced the bulb and passed the state inspection! Many thanks to Advance Auto!!

An Ok Bulb, but may die within a month

The bulb looked and worked well, but within two months it was dead. Luckily I have one more of them, but I have to hope that one doesn't die so quickily. Read complete review

The bulb looked and worked well, but within two months it was dead. Luckily I have one more of them, but I have to hope that one doesn't die so quickily.
I am using it in my third brake light and made sure there wasn't any fingerprints on the bulb or any water inside that could have caused any problems.

I hope you have better luck than me if you try this bulb. Only a 30 day warranty this item so I guess it is "Buyer Beware."

I installed these lights in place of my OE bulbs in my 2011 Nissan Altima. Good fit, increase in brightness and visibility. They have a brighter white looks. Cheaper alternative to LED lights and still provide a similar look.

Comments about Sylvania 921 SilverStar Mini Bulb, Pack of 2:

One of the first things I did with new Highlander was to replace the stock back up bulbs with these. Very cool color,and as a added bonus, they are way brighter than the stock 921 bulbs that came with vehicle. Have put these bulbs in both of my cars and will continue to do so as needed.

          • Q:

            Placing this in a car's plastic backup light fixture with a plastic lense in close proximity. How is the heat production versus a standard blub and does it present any concerns on damage to the plastic fixture?

              A:

              Heat output should be minimal as long as this bulb is correct for the vehicle’s backup light fitment.

            Will this be the replacement bulb for the front corner and rear corner bulbs? And I am looking for the replacement bulbs for the tag lamps as well.
