I wouldnt use red lenses. Its actually illegal on bikes to have red turn signals. Running/brake lights must be red, signals amber(i think thats federal regs, but it may just be PA). I installed a turn signal kit from
www.electricalconnection.com on my Rebel before I sold it for my Savage and I just installed another on the Savage. Very worth the $50. You want p/n 01315 if you have a Savage before '03. After '03 its p/n 01318. All the wires are easily accesible under the front seat.
