What's the 2019 Ford f550 headlight bulb size?

Your heavy duty 2019 Ford F-550 is going to use an H13 sized headlight bulb. If You're going with the old style halogens, the cost for a dual pack is around $27, and serves as Your fog light, too. Singles run about $16, so it's actually cheaper going with the two-for in this case. If this is Your first time replacing the headlights in Your truck, here's an overview of what You'll need to do. You've got to release the spring clips with a screwdriver to remove the grill. Once You've got it out of the way, You'll remove the housing, which is head in place with four bolts: 1 at the top, two on the sides and one on the bottom. Once You've got those out, You can just pull the headlight housing straight out, and then simply unscrew the previous light and screw the new one in, and reverse the tear down You just did, after which You can go forth and shine on!
