Awesome! I'm actually working on the same thing this week as i extended the bumper for a deck. I went with
similar lights. They actually have an orange blinker integrated, but i went with two for more visibility. I'm just going to surface mount them in the dip with some holes. I thought about putting guards or something to protect them, but i think they'll be fine for now. The slots look real nice!
I'm working on a trailer plug as well and determined i need a converter to join the blinker and brake lights into one wire. Ill wire
this before my plug junction box to handle that.
What are you doing for reverse lights? I haven't found exactly what i'm doing yet.
