Any Other Parts Needed When Replacing Incandescent Trailer Lights With LED Lights

Question:

I have oval trailer lights that use a grommet to hold them in. The number on them is ST1P2. They look like your ST70RB. Are the STL22RB led lights a direct replacement? I want brighter lights. I read that LEDs sometimes dont work because they have the wrong resistance and may flash too quickly, hence needing extra resistors or flash controllers.

You will want to measure your existing oval lights to make sure they will match up to the dimensions on the Optronics lights.

The Optronics LED Trailer Stop/Turn/Tail Light, part # STL22RB, will work as a LED replacement for the Optronics Oval Trailer Stop/Turn/Tail Light, part # ST70RB. They would both fit in the Optronics Rubber Grommet for 6-1/2 Inch Oval Trailer Tail Lights, part # A70GB. They would use an industry standard 3-prong plug like the Optronics Straight 3-Wire Pigtail for Sealed Trailer Stop/Turn/Tail Lights, part # A45PB.

On most vehicles the LED lights will NOT cause a hyperflash situation where the lights will fast flash similar to what your factory signal light does when the bulb is about to burn out. The only way to know if it will cause that situation on your vehicle is when the LED lights are installed. If that situation happens you will need to wire in the Putco LED Light Bulb Load-Resistor Kit, part # P230004C, to each light socket that has an LED bulb and flashes.
