Trailer light breakers

[Brad Townsend]

I was wondering if anyone was familiar with the breakers for the trailer lights. I have an 88 Newell the trailer breakers are located in the right rear outside compartment. Seems that the running lights on the trailer keeps blowing after I reset the breaker. Not sure if it is in the breaker switch or where the wires connect, perhaps a relay, size is abour 1 x 2 with about 5 or 6 blades at the bottom.
Any help would be appreciated. Place for parts also.
Thanks
