Question: I need 921 12V W16W bulb for my 2006 Hyundai Sonata brake light. Would this work on my car?
Document: So, this is my third model of Silver Star light bulbs.As others (1156 and 1157) I do recommend it.They do not look blue when lit up. They are crispier and slightly stronger than regular type.The only further upgrade would be putting a halogen...I used them in my two cars and both work great.As I previously said: to see full difference (between regular and Silver Star) - start the engine.
They work great and put out a good amount of light, but aren't as white as I thought. They are still very yellowish like any other bulb.
What can I say? These work perfect. The hardest part was getting the old bulb out. These fit very well and the light is brighter than the original equipment. This is another product that it pays to order a few extra.
Excellent OEM replacement bulb. Most automotive applications include Osram/Sylvania products, so the fitment is usually dead on.Make sure you check to see if you need the 912 or 921 as they are the same size, but use different electrical draw ratings. If you use one in place of the other, you risk diminishing the life of the bulb.
I was hoping to improve my reverse light output for better sight. So, I purchased this item in hopes of doing so. I have used Syvania headlight bulbs before and they are great.This time not so much, I guess I was just expecting too much from a little bulb. If you want to replace an old bulb or one that goes out, this is a great choice, if you need more light output, don't expect much from this one.
Replaced 1 back-up light on my car;  While the bulb doesn't appear to be dramatically brighter when viewed by itself, when you view it side by side with a standard bulb--there is a vast difference. The difference is not so much being dramatically brighter, but it is a much whiter light and does illuminate more clearly.
I've bought two packages of these bulbs to replace the cargo and 3rd brake lights in my 2004 F150. These replacements are MUCH brighter than stock. One of my friends even commented how much brighter they were compared to his truck. That's a great compliment to this bulb, because who even notices cargo light bulbs? Buy these. You will be extremely pleased with their performance. They are extremely WHITE. NO blue tint.
No complaints, installed the bulbs and they worked fine. Would buy again. Only thing is that I only needed one bulb and they make you buy 2.
I would buy these againI replaced an original bulb on a 2003 Lexus ES300.It seemed to be a bit brighter than the remaining original, but not noticeable.I was planning on replacing both reverse bulbs, but now will hold on to the other new one since they look very similar when lit.
If you care what the visual effect of the bulb is on your car--plan to replace these in pairs; the difference is very apparent. good product.
