Replaced both low beams in my truck, even though only had failed. That’s what the General suggested. Pulling the air box to get the passenger side was really easy. Not difficult on the driver side although pulling the accessory battery to get the driver side one was a bit heavy to lift. While I pulled the air box to get to the blown one on the passenger side I replaced the the air filter. The air filter was dirty as heck, I guess it’s been a few years since I’ve replaced that.

Technically it’s called a “combination” H11 bulb, even though it’s only a low beam, with one filament as it’s driven at a lower voltage during the daytime to serve as daytime running lights. Kind of a clever idea – under running a bulb can serve that secondary purpose of daytime running lights while avoiding having a whole second light bulb assembly.
