Not bright enough,
Verified Purchase(What's this?)
I bought these to replace 3457NAK front turn signal bulbs, but these aren't bright enough. 3457's are rated at 502 lumens, I'd say the brightness of these LEDs are about 25% of the filament bulb... so it would be visible at night, but in bright sunlight they wash out too much. It would have been nice to know the rated lumen output of these bulbs prior to buying them.
Some other reviewers commented that the color was too deep; the ones I received were pretty close to the picture. In any case, since they're too dim, I'm not using them on my car.
UPDATE: I posted a picture that shows how bright this bulb is compared to the original filament bulb as well as a competitive product. These probably put out about 70-80 lumens, much less than a 3157 or 3457 bulb.

Because these are 3157 replacements not 3457.. Try those and see what happens

3157 is specified to product 402 lumens, these LED bulbs aren't even that bright, not even close. See the comparison picture I added to the product image gallery. I compared it to another LED bulb, which produces 140 lumens of brightness, this product is even less than that.
