You can get a Kuryakyn Run-Turn-Brake module, for around $30, maybe less, or a deluxe Kury RTB with chromed bezels and red lenses for $40-something. The brake & turns all flash 3 times, then go solid in 'brake' mode. If you just buy the module alone, you will need to do something with your amber lenses, possibly like Renegade Rick did and get a small can of Testor's Candy Apple Red translucent paint, and spray the lenses lightly for color. They do the job!
