This does not have anything to do with your trailer problem, but keep in mind that a 7 year old battery is living on borowed time.

Not so fast there Chester!!!

From the OP's discription, I kinda suspect a shorting condition on the trailer or at the flat-four connector at speeds above 50 due to ill fitted lights or wiring flappin' in the breeze!!!

Any short will blow the fuses for the lights.No such thing to have a short and not blow a fuse.

unless it was installed without a fuse, and it is very very common, that's why you check, don't take anything for granted absolutely nothing, the one time you do is the one time you learn a very very important lesson.
