The bulbs are non-replacable on these, Ford forces you to buy a whole new housing when one burns out lol (thanks Ford)... Luckily they
should last 50k hours.
I've seen aftermarket headlights that have heating elements built into the lens before... But I don't believe I've seen any for broncos AND they're usually over 1k.. way too rich for my blood. Especially considering most aftermarket lights only have a 1 or 2 year warranty
Some sort of set of lights on the bumper would be my best.. and seemingly only option.. but id want to go with LEDs.. so I'd have to look high and low for some that get hot enough to work in a snowstorm.
I've had hella 700ff's before on a prior vehicle.. and the damn things got hot enough where they would crack the lenses when it was snowing lol.
Living in the North can be annoying
