Hi Are taillights STL8RGB and STL9RGB a set of the same manufacturers lights? One is driver side and other is passenger side... Do they come with butt/ heat shrink connectors? If no, what PN works in this application? Is it a good idea to place another piece of heat shrink over these for more water protection on my jet ski trailer. PN =?

Hello Dave,
Yes, the Combination LED Trailer Tail Light - Submersible - 6 Function - 11 Diodes - Passenger Side # STL8RGB is the better half to the Combination LED Trailer Tail Light - Submersible - 7 Function - 14 Diodes - Driver Side # STL9RGB.
The lights use 20 gauge wire, so you will need a pack of the Deka Heat Shrink Butt Connector - 22-18 Gauge - Nylon Insulation - Red - Qty 5 # DW05743-5. When I rewired my boat trailer I went ahead and put Primary Wire Heat-Shrinkable Tubing - 14-10 Gauge - Black - 3/16" Diameter - 6" - Qty 25 # DW05449 over the butt connectors as well. It gives me peace of mind having the extra layer on marine applications.
If you do not have a heat gun, the Trades Pro Dual Range Heat Gun w/ Nozzles - 5-Piece # ALL836717 works great!
Do you have a specific lake you like to go out on? I fish some local Bass tournaments here in Missouri out on the Lake of the Ozarks and Mark Twain Lake.

Hey Dave, Did you have a chance to try out the heat shrink tubing and connectors on your jet ski trailer? I'm curious if the extra layer of protection gave you the peace of mind you were looking for. Your experience could really help others considering similar upgrades!
