Dumb question about trailer lights..

I'd fill it with a flush rubber firewall plug .... probably be cheaper than JB Weld

 

Or NOT, as the case may be......LOL

 

I would suppose they would. Maybe add alittle silicone to seal it in... I found these after a quick search. https://www.fastenal.com/products/details/0712301

 

Just a thought but Grote used to make 2 and 3 inch round reflectors with their own sticky tape. Whichever one covers the holes

 

Get some aircraft aluminum duck take. We called it 500 mph fix it. In the military.

 

Stop by a welding shop, have them punch out some aluminum discs, and just weld them over the holes. Do it right the first time and never worry about that again. Stay away from any putty or fillers, will fail sooner or later. Or swap all the lights over to LED's, should last longer than your time behind the wheel.

 

The discs aren't a bad idea. Make it look better than putty or worn out tape.

 

All the time your wasting fretting about those lights you could have fixed them properly for less money. Sheesh
