Set your "Headlight" to LargeGreen (position 01, I believe)
Set other lights to Slowsmallgreen
Consuls (And me) : Use Blue Colours
Set your "Headlight" to LargeBlue (position 01, I believe)
Set other lights to Slowsmallblue
If you are not on this list, you are only a Warrior, and CAN NOT change your ship lights:
Format : Rank: Name (Forum Name)
Mandalore : Billy Bishop (Dieter Schprokets)
Consul: Diana Blane (Malexa)
Consul : Sagittarii (Casero)
Consul : Dha Piruna (Flo)
Consul : Ge'tel Gratua (Lanakov)
Consul : Briikase Uj'Alayi (Sassafras)
each set of changes only costs one million credits. So, you type /pimpship and edit 100 lights, and it costs the same as typing /pimpship and buying 1 light.
Uh, one little note about not changing the lights - if you're using any Stingers, they have all blue lights by default, and some other ships might as well.
Perhaps it'd be better to have all Warriors use a specific different color, just to avoid that?
