I have 5 K-line 21" Amtrak superliners. On one of the cars the red marker lights on both sides of the car do not light. I have not yet investigated the problem. They appear to be very small red colored bulbs. If I convert the car to LED lighting, what size and shape LED might fit in the space now occupied by the bulbs. Would I then be able to attach them to one of GRJ's lighting strip boards along with the white LED lighting strip?
Thank you,
Ron
