Question:

Im looking to install some kind of LED light on the back of my older horse trailer. I want something that ties in with my running lights at night but also has an on off switch. Is there a way to that with this light or can you recommend something else.

Expert Reply:

You could certainly use Opti-Brite LED work light # TLL48FB on your horse trailer and put it on a switch but having it wired into the running light circuit could have some unintended issues. Specifically, if you forgot to turn the switch off and drove away with the light still on you would blind driver's behind you! If the trailer has a battery I recommend wiring the light to it directly via a switch.

But if you want to go ahead and wire it in line with the running lights then all you will need is an on/off switch. My go-to switch for this is # PK34513. You would tee in the power wire to the running light circuit. The other wire would go to the light power wire. The second wire on the light is the ground wire. When the running lights are on you would just flip the switch to turn on the work light.
