The front brake light switch on late Lemans and early Cal III with Brembo master cylinder costs about $15 from Guzzi. Radio Shack has the same switch for less than $3, and you don't have to ride around for two weeks with no brakelight while waiting for the Guzzi part to come in. Take the old one in and ask for a Micro Switch to match.You'll have to solder on the wires from the old switch and remove a small metal strip which apparently is an actuating lever--it pulls right out.
