Review: ⭐️⭐️⭐️⭐️⭐ Awesome reverse lights — bright, solid build, great upgrade - Perfect for reverse lights — gives my car serious brightness while backing up Solid construction — feels durable, not cheap or flimsy Fits snugly and installs cleanly, no wiggle or loose fit No bulk — looks seamless, almost like OEM Great value — works so well there’s truly no need to buy something more expensive If you’re looking for a strong, affordable upgrade to your reverse lights, this is it.
Review: Absurdly bright. - Absurdly bright. Like, really, really bright. Installed in the cargo light sockets on a 2003 Tundra. Lights up the bed, driveway, parking lot, etc. at night. All the guys in the weekly MTB group groan when I turn on the lights after the ride and blow out everyone's night vision. My only complaint is that they have started to flicker, which my technician buddies indicate is likely the bulbs failing. However I got about four years out of the pair, so still pretty satisfied with my purchase.
