2013 Hyundai Elantra - Lights burn out

Are you obtaining the replacement parts from the same place? If so try a different vendor. Sometimes a vendor will get a stock of bulbs which are all defective. I’ve had that happen. It’s also possible your alternator isn’t working correctly. If you have the know-how, measure the battery when the engine is running, right after the first start of the day. It should measure 13.5 - 15 volts. What do you get? If it is the actual bulb filament that is failing, this doesn’t sound like a battery, wire, or connector problem to me.
