These bad boys are bright! When I'm backing into parking spaces that have faded lines these lights really help in situations like that.
I ordered several lights to upgrade my 2004 F150 from F150LEDs including the rear turn signal /tail lights, the backup lights, dome and gear shifter lights, front turn signals and the side marker lights. I had not problem installing them after watching some of their installation videos. One of the videos was a out of focus for a portion, but the directions were accurate so I was able to install them fine. I did have to flip some of the bulbs around to get the polarity correct, but that was described in the video so I knew what to do. All of the lights are working great and have greatly improved the lighting for my ol' girl. I would recommend F150LEDs!
Plug and play 10 x better light.
