Nav Light Removal for Replacement

[Isham]

I am going to install the Whelen Nav/Strobes.  Removed the screw on one of the existing nav light lens today just to see what I needed to pull off -- the old nav light lens is stuck hard to the wingtip.  I pulled by hand but it does not budge.  Must be installed with some kind of sealer around the edge.

Any suggestions on how to get these off without damaging anything?

There is silicone sealer completely under the light. I have used a utility knife blade, and a thin putty knife before. I have also used some twisted Kevlar thread pulled back and forth like a saw to cut through the silicone before. Just be slow and patient so you don't do any damage.

Like Tom suggested. Use a thin blade puddy knife and work your way from the narrow end forward. Going around from top to bottom edges.

If you don't have Kevlar thread in your toolbox, perhaps several strands of dental floss would work?

I, for one . . . really appreciate it.

I also agree. Lots of great ideas. Thanks

It might, but I have never tried it. I did use some braided fishing line once.

Dental floss breaks easily. Fishing wire is your best bet. Wrap the end around dowel rods for leverage.
