Need repair or replace advice Fenix L1T

I bought several Costco package deals of the Leatherman Blast and Leatherman LGX200 (Fenix L1T). I gave them for gifts. I found out that one of the flashlights doesn't work. I tested it myself disassembling and replacing parts with my working one. It appears that it is the head that is defective. These are all gone at Costco so I can't exchange it. I see we can send it to Leatherman and they will send a replacement but will probably be a different model. These fit the holster that holds the Blast and are great little utility lights. My question is there anything that I might try to get this light to work? Can I contact Fenix and just get a replacement head? Any suggestions.

Thanks for any help.
