Dodge 18681 Viper - Manual (Page 193)

License Plate Light
Twist off sockets counter-clockwise and pull out bulbs.
Replace as required.
Headlight Aiming
The headlights on your new Viper were aimed at the
factory. The factory setting was made at a no load setting.
A great increase in weight will change the aiming and it
may be necessary to readjust the headlights if you
typically carry an excessive amount of weight in the
trunk or otherwise suspect misalignment.
