10 tail lights, WOW! that is a lot of lights. Are you also talking about clearance lights? As, stated, if talking about tail and sop lights, you will need to check your flasher unit to make sure it can do LED. If not you will have to change or install 50 OHM resisters in line. I had two simple two prong flasher units, was very cheap to replace. I now have front and rear LED parking and turn/stop lights. LED lights will use less current draw in case you need to leave parking or emergency lights on for extended period. As far as clearance lights, there is nothing special needed to install new complete assemblies. I personally did not replace my clearance light with new ones, but simply ordered LED bulbs, since my lenses were still in good shape. Much cheaper way of turning clearance lights into LED. If you want to just change the bulbs on the clearance lights, if the number is 193, just simply do a search on EBAY.
As far as your tail/stop/turn lights, I would look for the part number and do a search for LED replacements. Good luck with your project.
