Please, put an odometer into SRV. It already have lights indicator and low and high beam, stop and reverse lights. Horn is not needed - we have turret, but odometer would be very useful in many types of activities on planets (srv races or other challenges) or as guide (for example: go 3500 meters, bearing 90 from this wreck and you will find hidden material cache). This odometer does not need total meter for a SRV. Two trip meters (A and B) with option of resetting them at any time during a ride would be ok.
