Default Low Beams turn off

I have been having a problem since June, this has happened 4 times since then that the low beams just turn off.
2 weeks ago we were in Florida, and driving down the road and the low beams just turned off, so we pulled
over and all the fuses seemed to be great, and we got back on the road and tuned the high beams on and about
20 min in the ride we checked to see if the low beams were working and they were. The next day we were
leaving Florida and the TB would not start, so someone jumped us off, and we went and got a new battery
and everything seemed to be ok, until last nite, riding down the road and the low beams shut off again??

Has anyone had any problems with their TB doing that. Someone said it could be the
High/Low beam switch or the relay??? Does anyone know if this is something I can
do, or the dealership.

Thanks
Jim

did you have the alternator checked to make sure it was putting out the proper voltage?

We had the alternator checked at O'Reillys and he said it was giving out the correct voltage and etc.

Thanks
