10 Pcs Super Bright 921 912 T15 W16W Backup Reverse Light Bulbs Canbus Error Free For Brake Stop Cargo Backup Lights High Power 2835 21SMD 6000K Pure White

so far, all worked - I have two complaints if these are used in RV applications for replacement lighting...1 - they are uncomfortably "white/white/close to bluish" - I will be looking for replacements - they are just too uncomfortable for me2 - they are not as bright as the 921 types I removed - had they been equivalent or brighter I might have been able to better tolerate the 6000K+ "white" glowon edit 6/26/2018: well, I've now spent some "extended" time with these installed. They're are still too "blue'ish" for my tastes, BUT, I did get to where I really didn't notice them. I'm also not sure they are dimmer than the 921's they replaced. I installed some of these in my sister-in-laws RV a couple of days ago, and they were definitely brighter than the lamps they replaced. I still look for a replacement, (based on emitted hue) but I am ordering more for spares and to finish out my sister-in-law's RV - I think my original opinion was based more on my reaction to the color. They sure are working "reliably"

So far work great, I bought these when it had no reviews, looks like its a good product. I will update if it fails. Well madeWorks on Tundra 2015 on cargo lights plus third brake light & both rear blinkers, but need to do something about the hyper flash.

I bought these for a 2nd time.. They are a great upgrade for older vehicles where incandescent or halogen bulbs came as original.. They have a bright white light which is what you want a dark parking lot..

Would not recommend. Only use these on the weekends in our camper, Several bulbs are burned out or fell apart. Only installed them in the middle of May this year. Lights started off bright White and now after a few weekends they are blue. Don't waste your money.

I've been replacing all the 921 regular bulbs in our RV with these. What a amazing difference in light output. More than double the light. These bulbs don't hot like the old bulbs, thus making the AC system work much better. Plus they don't use 1/10th the power, so your battery will last so much longer if you are dry camping.

These are extremely bright n very well made lights however they won't fit in most housings that use this bulb.

I have to replace about every (3) months. They are very bright and work beautifully until then. 50/50 whether I would recommend.

I have to fill out paperwork in my truck every night and swapping out my dome lights with these has made a HUGE difference.
