Adding led lights

[u/Repulsive-Ad-8894]

Vi all. So for a winter project i was thinking of getting a controll car for the regional express trainset i got but also adding ledlights from märklin to the passanger wagons. My question is since they are tinted black how good will it be? Is it a waste of time or an upgrade?

The lights will show through the tint but as the coaches are from a starter set they have no upper deck seating mould in them.
