Ztron lab tail light

I bought the tail light some time ago and I decided to check it before installing. I can't get it to go. It appears to be dead. The company is not in business anymore and replacing it with same is not an option. Does anyone know of a suitable replacement for the Ztron tail light. The Ztron position and side strobes are brilliant.

I had planned on Ztron as well but when I couldn't get them anymore i went with FlyLeds. Glad I did, I love them. Had to change a little wiring but nothing major.
