Not boats but.......

I had some fog lights installed on the back of my truck to help when launching boat at night, pulling trailers, etc. I had a reputable guy do it, and no problems noted. Last night I flicked the switch, and although the lights come on, I can hear ( and feel) the relay popping/clicking. I have not noticed this before. Do I need to take this back and let him replace/fix something?
Just never had to deal with this before.
Thanks
Tom

yes i would take it back to him he should take care of it for you
