Hello everyone, I'm new here, and really appreciate everything I've learned so far. I working on my speedometer, everything works, but the little colored lens, (for amp oil, and high beam) that are taped onto the back of the gauge have fallen off. What the best way to re-attach them? I don't think clear shipping tape will hold for very long, and Gorilla glue say not to use it on certain plastics. BTW - awesome website!
