One of my lights went out. The company said they no longer made the yellow ones, so they refunded me 100%. I bought these replacements. They're smaller, inexpensive, look pretty good, and extremely bright. $27, so if a rock takes one out I'll just buy another set.
Edit (3-4-23) I'm using these as marker lights to be seen by other drivers during the day, not to increase my ability to see at night.
No way I can run them at night without blinding other drivers and in the daytime they're borderline obnoxious- which is perfect. These can be switched from white, yellow, both. I only have a one-way switch, so I didn't wire the white in. I think with both on they'd be nuclear.
