Set the look-ahead extra aspects for the most recently defined style (defined using the define_style property).<br />
This property only makes a difference when the "limit train lookahead to signal aspect" game setting is enabled.<br />
This limits the signal aspect which the hypothetical train driver can "read" from the signal without affecting signal aspect propagation to other signals, or variable <span class="code">extra_callback_info2</span>.<br />
Example values could include: 1 for traditional banner repeater signals, or 0 for shunt signals.<br />
The value is clamped to be less than or equal to the value set in the <span class="code">extra_aspects</span> property.
