So I finally replaced my LED fog bulb on my 2019 with a 3000k bulb. Now, I haven't seen anyone else offer a replacement since it's not a traditional bulb until I came across Junack. They offer a direct replacement in either 6000k white or 3000k yellow. Both advertised as brighter than the OEM one. Now previously, I did 3x layers of Lamin-X on the fog housing but it could not get me that deep, golden, jdm look. That's the problem when you shine a white LED light through a yellow film. In the before and after pics, you can see the difference in yellow. I'm sure without the film, it would still be nice and golden but I plan to keep the film as 1) it will protect the housing and 2) it gives it a nice look when the lights are off Also, you can see what the stock fog bulbs look like below Posted via the PriusChat mobile app.
There isn't a bulb number on it. It's not a traditional bulb and a specific LED. hybridpit has the same one here : LED fog Lamp Bulb for Toyota Prius 2020 - 2024 It's pricey but I love the end result Posted via the PriusChat mobile app.
