I did mine last month. 4" LEDs with 1" white LEDs for reverse. I put my reverse lights above & to the inside of the LEDs. I used light bolts for tag lights.
I went last week to get my state inspection & 2 of the shop guys were standing behind the Jeep discussing how the "aftermarket reverse lights" would blind any drivers behind me where I had them mounted. They said they were inappropriate & should be pointed downwards as not to blind said drivers behind me. I couldn't help but laugh when I told them that if I was blinding a driver behind me with my reverse lights, he had a HELL of a lot more to worry about than the lights.
I guess that kind of embarrassed & pissed them off because they told me I failed due to lack of tag lights. I got out & stuck my finger under one of the light bolts & showed him that, in fact, I had tag lights.
Needless to say, I passed the inspection but didn't make any new friends that day.
