I don't know what you like,...everyone is different.
All anyone can do is make suggestions,...but that is based on each persons preferences....you may not like what they like.
I think you truck looks perfect just the way it is.....but obviously,.. you forgot to get a "Mod bug flu shot"......so leaving it the way it is...probably isn't going to happen.....lol
To give you my best "opinion" on what to do next,..I would need a bunch of info.
do you tow,..and how much
how much are you willing to spend
why do you need more lights...are you in the woods at night?
what is the end result of how you want it to look.
do you like chrome
do you race
do you off-road
do you enter it in shows
do you want the biggest tires you can possibly fit
do you work out of the bed alot
I can think of about a million more questions,....but ultimately,..it's what you prefer.
