The ELFA (Electronic Left Foot Accelerator) system by Veigel allows for optional use of a left foot accelerator. It features a key or push button switch to select between the left foot pedal or standard right foot pedal. The system defaults to the standard right foot pedal on startup for safety. The Veigeltronic Accelerator Switch was designed to not interfere with the vehicle's accelerator signal. The left foot pedal is manufactured by a major OEM supplier to ensure quality. Vehicle specific kits include a pre-formed pedal bracket to integrate the left foot pedal.
