Question:
Iam looking to replace an Optrinics boat trailer light passenger side with a model number ST-36 RH. It has a three prong plug. I realize you have a one LED substitute in STL0066RBG. But do you have anything that is not LED that will replace the ST-36 RH with a three prong plug or even one that gets hard wired?

Expert Reply:
Hey Jeff, you could use the part # ST17RB for the driver side and the part # ST16RB for the passenger side. These are both three wire assemblies with incandescent bulbs like you are wanting. You'd just need to cut off the 3 prong connectors you have and hardwire them like it sounds like you already knew you'd have to.
