<h4 id="signals_style_lookahead_extra_aspects">Set custom signal style train look-ahead extra aspects (mappable property: signals_style_lookahead_extra_aspects)</h4>
<p>This applies to the most recent custom signal style defined using the <a href="#signals_define_style">signals_define_style</a> 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 0x18.<br />
Example values could include: 1 for traditional banner repeater signals, or 0 for shunt signals.</p>
<p>The property length is 1 byte. The value is clamped to be less than or equal to the value set in the <a href="#signals_extra_aspects">signals_extra_aspects</a> property.<br />

<h4 id="signals_no_default_style">Set whether custom signal sprites should not be used for the default signal style (mappable property: signals_no_default_style)</h4>
<p>This applies to <a href="#a3signals_custom_signal_sprites">Action 2/3 Signals (Feature 0E) custom signal sprites</a> for this GRF.<br />
When enabled, this GRF is not used for the default signal style, it is only used for custom signal styles defined with <a href="#signals_define_style">signals_define_style</a>.</p>
