These things are insanely bright and have survived two ice storms and triple-digit summers. The only negative is the price, but it's a great product so I can justify it as GTR lighting is top tier. Installed in a 2010 F-150 King Ranch with aftermarket taillights. ### ⭐⭐ Does not work with sealed light housing. *by B***D on December 9, 2024* Lights are probably great, but they do not work with the 2024 GMC Sierra. The housing is sealed. ### ⭐⭐⭐⭐⭐ MUCHA ILUMINACION *by L***R on October 25, 2023* Investigué muchísimo antes de comprar, los materiales de fabricación son excelentes, el patrón de iluminación es lo que los destaca del resto de las opciones ya que iluminan a 360" e integra la lupa delantera (15 chips en total) que lo hace el complemento ideal, quedaron instalados en un ford Fiesta 2011 mk7.Saludos desde Argentina! ## Frequently Bought Together - GTR Lighting LED Bulbs, 921 / T15 Ultra Reverse Light Bulbs(1 pair), Worlds Brightest Plug and Play Back up Lights, Pure White, Error Free.
