In the last few years, there have been multiple hand controls released that offer multiple vehicle controls built right into the gas/brake lever. Using only one hand, you can operate the gas, brake, turn signals, wipers, heater, windows, and more! These multi-function controls integrate directly into your vehicle's computer without the need to add additional mechanical levers. These integrated controls are available on many hand control models. Please give us a call for specific applications for your needs and vehicle type.
