Possible premature headlight/connector burnout Ford Focus SE 2013.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Yeah, wiring the headlights together is about as good an idea as using duct tape to fix a leaky radiator—tempting, but bound to cause bigger problems. If both bulbs keep burning out, you likely have voltage spikes, poor grounding, or excessive heat at the connectors. Start by checking the alternator output—if it’s overcharging (above 14.8V), it could be frying the bulbs. Also, inspect the headlight grounds—a weak ground can cause resistance, leading to overheating. If the connectors look melted or discolored again, you might need a new headlight harness.
