Starting a new business

One of the most satisfying (to me) cosmetic add-ons I've made is a 140 ci badge. Not sure why, as most people under 50 in Oz don't really know what a ci is. But I do (I was born in the 50s) and I reckon a 153 ci badge would be really good. Who'd know? And we could get an urban myth started.
 
Can you make one that is blank and comes with magnetic numbers. so just in case I come across someone who has a bigger one, I can upgrade on the fly?
 
It needs to be chromed, streeeeetched, lowered, and be back-lit in flashing LEDs that change colors.

Once you get these made, I will trade a pint of blinker fluid packed in dyno room air for 10 of them.
 
Say Daryl, don't limit yourself to motorcycles. You are into guitars as well so how about a badge I could put on my cheap Garrison G10 that says Gibson or Martin?? The possibilities are endless!!
