You'll need:
- Bathroom grab bar ($25 at your local hardware store)
- Hardware (nuts, bolts, fasteners) to mount bar on bumper
- Bed liner paint spray can ($8)
- Auxiliary lights
You can use some fine sandpaper such as 800 or higher, at the end of the day this is going to be a pretty important part, as would adding a primer, since this will sit in front of your bumper and would therefore be in contact with small projectiles.
The second thing you need to do is to place the bar on top of the bumper cover, to figure out where to drill your holes.
Then you'll need to remove the bumper cover, drill the holes. Note: the bumper cover is a little filmsy, you might want to consider reinforcing with a flat metal bar which will sit in between the cover and the bumper mounts.
Then you want to place your auxiliary lights on your mount (off of the car) so that you can drill your holes.You'll want to make sure that your holes go through the bar level, otherwise your lights will be tilted.
You can then add your bumper cover back on the bumper, then bolt on your bar and then the lights. Wire everything up and you should be good to go.
