Using you weld-on tab outline it with black felt pen
Weld it on, then paint
Note where I cut off the bumper ends
Great fit, looks good
Thin line for clearance
Bought a set of PIAA driving lights. These puppies are NICE! They have been setting on the shelf for nearly 2 years and I got around to welding them onto my front bumper today...finally.
Grind down some paint in the area you want
1) First thing I did was to clean some paint off my selected spot for the lights
2) Then take a black felt tip and outline where the light tab is to sit
3) Weld it up
4) Apply paint
5) Hook up electrics and drive
Time to attach brackets: about 30 min
Tools: Welder, angle grinder
Cost: Mostly up to you on your choice of light, but I grabbed these PiAA's on a close out at half price, I paid about $160 for the pair.
While I was at it I also clipped off the extensions on my front bumper as you might notice in the last 3 pics.
