Dumb question about trailer lights..

so I recently bought an end dump. It's a dinasour, a 1985 Raven aluminum. It's in over all good condition for its age, but has given me fits recently with some lighting issues. The thing has an insane amount of lights, probably over to 30 on each side. I'm constantly having to change them out and it sucks. I guess my question is, is there a legal way to eliminate and permanently cover up some of those lights? My old Travis aluminum end dump only had three amber lights on each side and it was awesome. Did some searching and couldn't find anything. Maybe that's a hint that this is a dumb question so forgive me for my ignorance.

not a great angle but if you zoom in you can see there is a total of 36 lights on the side. If I could take them off and just leave a few so it will be legal, that would be sweet. I don't really want to roll down the road with 33 empty light holes, so I searched if there was such a thing as a light hole cover and nothing really seemed to exist. Any ideas would be greatly appreciated!

 

Would I just leave the hole open? Would you happen to know how many I have to leave for it to legal? This is in Texas if it makes a difference.
