Wolfie,
Sorry for the delay. I'm not sure where you mean? But I can say that tape won't be part of the finished product. Thanks.
The location of the guns out on the wingtips originally caused me to go with fiber optics but after breaking one here and there during handling I rethought that decision.
Rebuilt every gun so that an LED would become part of the gun itself.
With wiring being bulkier than fiber I also had to reroute connectivity.
But eventually even without light block applied it far outshines what fiber could transfer.
And there are four in blue and four in green.
