they are parking and signal lights, every RAM owner has to take a second look when I pass by with these on, I saw it somewhere on the internet on a custom ram their were only four fixed red lights on each side. I did six, and I can change there color. the directionals are also sequential, the tow-haul mirrors also blink as well as stay lit. After all that I just had to install the cab lights seeing that 1500 don't come with them, the whole truck inside and out are all LED,s Couldn't help myself. Got hit head on some 30 years ago.....wasn't good!! So now I want you to see me comin. Thanks again for the compliment! As I said your truck also look great well taken care of. I love seeing that.
