| (2)  The municipal officers or a municipal official  | 
| designated by the municipal officers, with the approval  | 
| of the fire chief, may authorize an active member of a  | 
| municipal or volunteer fire department to use a  | 
flashing red signal light not more than 5 inches in  | 
diameter siren and any combination of flashing red,  | 
white and amber lights on a vehicle.  The light lights  | 
| and siren may be displayed but may be used only while  | 
| the member is en route to or at the scene of a fire or  | 
other emergency.  The light must be mounted as near as  | 
practicable above the registration plate on the front  | 
of the vehicle or on the dashboard.  The lights may be  | 
| mounted on the roof, rear deck, front grille or  | 
| dashboard of the vehicle.  A light mounted on the  | 
| dashboard must be shielded so that the emitted light  | 
| does not interfere with the operator's vision. |
