Hello David,
The Lucas Style Tail Light came from Amazon and it was only like $11.00.
https://www.amazon.com/gp/product/B00230GLD0/ref=oh_aui_detailpage_o09_s00?ie...The tail light uses about the same bulb as the stock bulb #1157, but since it does not have the elaborate reflector system as the factory light it wasn't quite bright enough. I bought a SuperBrite LED Bulb.

If you are going to mount it the same as I did you will need to make a bracket for it. The threaded posts on the Lucas Light are just slightly wider apart then the width of the license plate bracket. I used 1/8" x 1 1/2" aluminum from the hardware store, I think Home Depot. The bracket is simple enough, you need something to fasten the Lucas Light to and then fasten the bracket to the existing license plate bracket.
I drilled and tapped the Suzuki License Plate Bracket with an 8/32 tap and used Low Allen Head bolts to fasten it. You will need to make a ground wire for the new taillight as it only has 2 wires and the license plate bracket is rubber mounted to the fender.
I wish I would have taken some pictures.
Somewhere on The Forum a guy posted a really neat cross that he fabricated to cover the holes in the fender from the original factory tail light. I am thinking it may have been the guy with The Purple Passion bike.
