Spyder Taillight help

So, I have these Spyder Taillights on my 2015 Pro:

The reverse bulb is incandescent, even though they were sold as LEDs. The light output in reverse is terrible. Anybody know what LED replacement bulb would work in these taillights and where I could purchase some?

 

Id like to see these mounted in your truck if you have a pic? I been looking at those myself! should be able to pull the reverse bulb out and read the number on the base of it and cross check it to an LED bulb though. I'm sure someone can chime in as to what it is though.

 

Thank you sir!
