For example, remove or change hats.

At night it is difficult for surveillants to be sure they are following the
The subject's vehicle can be better kept in sight if it is
distinctive. If the chance presents itself, attach a piece of reflector tape
to the rear of the vehicle.
The surveillant's vehicle should also receive some attention. The dome light
should be disconnected so that the light will not show when a door is opened.
One of the headlights and the license plate light can be wired to permit them
to be turned on or off independently. This will permit a change in the traffic
