AutoLite Led Festoon Bulbs 31mm 1.22" DE3175 DE3021 DE3022, Automotive Interior Car Light Bulbs, White 6000K with CANBUS Error Free, Best for Led Dome Map Light (31mm 1.22" Led Festoon Bulb)

Good

I replaced my incandescent bulbs in my Pontoon Navigation Lights with these, and what a difference!! Super bright in comparison. My original bulbs dimly lit the Nav lights up, and if you stepped off to the side, you could barely make out that the lights were on. These on the other hand, light up the plastic lens, even in bright sunlight, from any forward angle. When putting them, make sure the heat sink on the back is facing rearward. Check your lights before putting the cover back on to make sure the polarity is correct.

I bought this for the dome light in my 1980 Corvette, which has a like new lens cover. Regular bulbs get really hot and discolor the lens cover, so I thought this would be a good replacement. It works great and hardly gets warm. I can leave the door open for hours when I am working on the car without worry about draining the battery. I have only had it a month, so I cant comment on longevity, but so far, so good.

At first I was getting annoyed with the lights in the back not coming on, but then I realized the prongs holding the lights were spaced out. After gently pinching the prongs, the lights were more snuck and work perfectly! Very happy with them. Great value!

Replaced the incandescent bulb in the boot light of my Ioniq5 due to the bulb being dimmer than I would like. This bulb fits fine and is much brighter than the stock light. They also fit in the sun visor lamps but I think those might be too bright for use at night.

Ok, this is the correct size for my FJ Cruiser, it just does not fit properly. I know why they give you 4 for a vehicle that only needs 2, because you will bend/break 2 trying to get them into the proper place..That being said, after you jam the things into about the proper place and snap the cover back on, they work great, much more light over stock lighting.

Noticed a slight flicker especially warming up. Other than that it works really great! Looks cool!!

Put them in my 2012 Nissan frontier, lights the cab up pretty good.
