Could Dual Trailer Parking/Turn Signal Light # ST52AA Replace a Single Filament Light on Tractor

Published 10/26/2016

Question:

My tractor has flasher lights on it like the ST52AA the lights have 2 wires with a single filament bulb . I assume one wire is a ground, this is a new tractor and I don,t want to buy one from the dealer. All the lights I am finding has 2 wires with a two filament bulb. Do you have a light to replace this.

The part # ST52AA has a dual filament bulb that has two brightness levels. One is dimmer for running lights and the other is brighter for stop/turn lights.

The two wires of this light are for the two brightness levels. What you could do though is run the ground wire of your tractor's wiring to the mounting stud of the light and the power wire of the tractor to either wire depending on how bright you want the light to be.
