Review on Yorkim DE3022 LED Bulb 31mm Festoon LED Bulb - White Super Bright CANBUS 10-SMD 4014 Chipsets - 3175 LED Bulb, DE3175 LED Bulb, 3022 LED - Car Interior Dome Map Lights - Pack of 4 by Luis Norman

I installed these on my 2013 Tacoma and I like them much better than the original bulbs. they are significantly lighter. (It's hard to tell the difference in the photos but see the attached images.) I like the whiter color they give off compared to the OEM bulbs. Measure your bulbs first, I was in a hurry and bought the 31mm first because I read online that Taco used this. (I read that online so it must be true) Well they were too small (maybe 31mm was for a 1st or 3rd gen taco). I went back and measured a standard 578 bulb (2nd generation) and it was about 38mm from the flat plane of the bulb. I re-ordered the 41/42 LEDs to even out the pointed ends and they fit perfectly. (The 41 also has 6 more LEDs. So bonus.) The rounded ends of the LEDs are smaller, but they fit snugly into the case and are pretty secure too. I have also attached some other images that may help others as a visual guide. I'll have to see how long they last, but they come in packs of four so I have spares.
