These are much brighter than the original factory bulbs. Easy to install but I did find out that they are positive - negative specific. I first installed and the bulb didn't work. Tried it on the other light socket and it didn't work. Tried another bulb and it worked. Hmmm? Then turned around and the other one worked. Seems they need to be oriented correctly to function. So if they don't work for you, flip around and try the other way.

Had this in the dome light of my car for several years now, never had a problem, shines bright to this day.

First off, the bulbs work, they just don't fit the 2002 tacoma without modification. One end needs to be crimped flat to fit into a slot on one side of the terminals. You can make it work but, I would rather just have the correct replacement.UPDATEThese lights will only work correctly with the key on, otherwise they are very din and will flicker. To solve this you have to add a resistor to match the draw of the original bulb.

These are much brighter than the OEM lights. I also like the white light, rather than the yellow of the OEM lights.I originally ordered these just to replace the burned out ones. I like them so much that I bought more to replace all of the interior lights. I just finished installing them and it is great. I can actually read a printed page under these lights pretty easily even with my aged tired eyes. I can't say the same with the OEM lights.Though it fit my Honda Odyssey just fine, they are wider than standard bulbs. So make sure you have the extra space for them to fit. You can guess from the picture of them being wider than standard bulbs whether it will fit your car.

These are awesome man. These these lights are insanely bright. They’re like headlights for reverse. I mean, I couldn’t see anything backing up now I can see everything.

Purchased these for our 2018 Rav4 XLE for the back dome light. They are to big and do not fit correctly despite being listed as the correct size.
