There are no graphics currently for underground LED signals. Are they sufficiently different in appearance as to warrant different graphics (i.e. such that the difference would show in the size of graphics in Pak128.Britain)? (And, if so, can you link to pictures showing the difference?) If not, one might just re-use the same graphics but call them LED signals and give them a lower maintenance cost.
Also, this is a pakset question, so I am moving this topic to the pakset discussion board. Please take care to post in the correct subforums in future.
