For the DIY'ers, Get a countersink bit,1/8 x 3/4 piece of flat stock. Cut 2 at 8" long, take one and hold it in place on the down bracket of bike.Then mark your two holes, 3 inch on center.Use countersink bit in drill or drill press.Use countersunk flat socket head cap screws & Nyloc nuts for a 2014 Street Glide. For the 2014 Electra glide ultra/limited that plan on using saddlebag filler strip kit, use flat head allen bolts 1/4-20 x 1".[The filler strip has two fixed nuts on them]. <SEE PICS> Under $10.00 bucks,and 20 minuets.

 

I don't think this can really be considered "cheaper" because you're spending $10. The way they come from CD doesn't require buying anything else. It's a great mod and all, but honestly, the tape that is on the rod is really sufficient for putting on the fascia like recommended. I haven't had any issues at all with mine. Nice work though.

 

And what are they lighting up mounted that way??

Maybe it's just the way the picture is posted but it looks like the lights are mounted to be seen from the side of the bike. Or maybe it's just to many spirits drank over the last several days!!!!!!!

 

Looks like the pics are rotated counter clockwise, which can screw with your perception - that's the tail housing at the top/left of the pic.
By cheaper, I assume he means as opposed to buying PVC 1/4-round and 3M automotive emblem tape which can run around $15.00 by the time you get them home. (this method keeps you from sticking the rods to your paint by mounting the 1/4-round inside the fender flares and the rods to the 1/4-round.)
