Firehouse Sign
Calls attention to the presence of a nearby fire station, so drivers are alert to the possibility of emergency vehicles suddenly entering the roadway.
Low-poly, 128×128 textures, and shares a common specular map with my newer (and upcoming) road sign assets if you use the Loading Screen Mod.
All my signs are props, so you need to use More Beautification mod to place them. They show up in the general props category (the park bench icon).
