Easy to install and great replacement
These replaced my old style halogen bulbs which were dingy and yellowed. These are super bright and of great assistance while backing up anywhere. Extremely visible to others and I get lots of compliments on my truck. First pic is the new and second pic is the old. You may want to replace your flashers to the newer non hyperflash relays because these will cause hyperflash which isn’t a big deal. The newer LED relays are about $4-$5 each.

Very worthwhie upgrade!
Wish I had replaced the standard bulbs in my backup lights long ago. It lights up bright enough for me to back my pickup along a gravel driveway at night. With the OEM lights you cannot tell the difference between gravel and grass. Also did not show a bulb error on my 2011 RAM 2500.

Great led lights
I ordered those lights to replace the cargo lights on my ford maverick, it came with less everywhere except the cargo lights.. this lights made a huge difference, so much brighter and white compared to the yellowish lights I replaced.

Good and brighter replacement for 921 halogen bulbs, just not as bright as I would like.
SLIGHTLY brighter than new Sylvania Halogen 921 long life bulbs, BUT NOT the 300% advertised, more like 20% brighter - thus the 4 stars. These only have 9 LED's per bulb, where similar but brighter bulbs typically have 15 LED's of the same size. No errors, no flicker, & where every other brand I've tried, fails to maintain cruise control if used in the 3rd brake light on my 2010 HHR, these bulbs from LasFit DO WORK with my 2010 HHR, maintaining cruise control functionality!!! I've used other LasFit LED bulbs, with a set of 3157 switchbacks purchased Nov 2022 still going strong for my rear brake / turn signals! I would recommend these if you're looking to switch from halogen to LED, overall, they are a good buy. All of the other LasFit LED bulbs I have tried, greatly outshine their halogen counterparts very noticeably, and even outshine some competing brands that claim bigger numbers.... While these are brighter and stay cooler than the halogen bulbs they replaced, it's really a shame that these aren't a lot brighter.

Used in the cargo light of my 2002 Ram 1500. They fit perfectly, and are super bright, you could almost sit on the tailgate and read the fine print books. Also replaced the high mounted brake light while I was at it with the red version of this bulb. Also a great bulb. Will see what the life span is now. Would buy again.
