Trail-Gear Weld-On Light Tabs are CNC formed from 1/8" thick 1010 steel, coped for 1 1/2" or 1 3/4" O.D. tubing, and have a 1/2" sized bolt hole. Weld-on light tabs are shipped unpainted and are sold in pairs.
These tabs also make great generic weld-on tabs for things like seats, seatbelts, or just about anything else you want to mount onto a piece of tubing.
